Pilot scale cofermentation of the xylose and hexose fractions of spent sulfite pulping liquor using recombinant strains or saccharomyces cerevisiae
Creators: name: Guild, Jeffrey Joseph
Publisher: name: University of British Columbia
Year: 2009

description: At the Tembec sulfite pulp mill, an existing ethanol fermentation facility currently ferments the hexose sugars from spent sulfite liquor (SSL) to ethanol using an industrial strain of Saccharomyces cerevisiae. While this industrial yeast strain achieves high fermentation efficiency on the hexose fraction, it is incapable of fermenting the pentose fraction (primarily comprised of xylose) present in the SSL. The plant Saccharomyces strain exhibits high ethanol tolerance, fast fermentation rates, fermentation at low pH, and resistance to inhibitory substances. Natural xylose-fermenting yeasts such as P. stipitis exhibit high ethanol yield on xylose, however, fermentation rates are slow, and tolerance towards inhibitors in SSL is low. A recombinant strain possessing both the advantageous characteristics of S. cerevisiae and the xylose-fermenting capability of P. stipitis could significantly increase the efficiency of ethanol production from lignocellulosic hydrolysate. Xylose fermentation would have a large impact on the economics of ethanol production in the facility. Tembec Inc. could increase the production of high-quality industrial ethanol by approximately 30% if the xylose present in softwood and hardwood SSL were cofermented with hexose sugars. Xylose-fermenting recombinant Saccharomyces yeasts (plasmid-bearing and chromosomal transformants of robust industrial yeast strains) were constructed by Prof. N. Ho, Purdue University, and tested on xylose-rich SSL at pilot scale. The pilot fermentation plant is an automated 1/1000-scale emulation of the full-scale fermentation operation at Tembec and operates continuously in complete yeast recycle mode under typical industrial (aseptic) conditions. While up to 100% of the xylose present was consumed in extended pilot trials with the plasmid-bearing strain (LNH32), no appreciable increase in ethanol yield over the current plant strain was demonstrated. The fermentation efficiency of LNH32 was comparable to results with the plant yeast strain, despite the fact that LNH32 utilized only 50% of the galactose. Incomplete fermentation of galactose by the LNH32 would seem to explain the lack of increased ethanol production, and due to xylose fermentation by the strain, a 15% increase in fermentation efficiency (based on available hexose sugars) would be realized over the plant yeast strain if LNH32 were capable of fermenting galactose. Finally, in laboratory trials with LNH-ST, a stable xylose-fermenting chromosomal transformant of a galactose-positive host strain, a 20% increase in ethanol yield over the parental strain and plant yeast strain was obtained in both hardwood and softwood spent sulfite liquors.

description: The Pyrenees is a collisional orogen built by inversion of an immature rift system during convergence of the Iberian and European plates from Late Cretaceous to late Cenozoic. The full mountain belt consists of the pro-foreland southern Pyrenees and the retro-foreland northern Pyrenees, where the inverted lower Cretaceous rift system is mainly preserved. Due to low overall convergence and absence of oceanic subduction, this orogen preserves one of the best geological records of early orogenesis, the transition from early convergence to main collision and the transition from collision to post-convergence. During these transitional periods major changes in orogen behavior reflect evolving lithospheric processes and tectonic drivers. Contributions by the OROGEN project have shed new light on these critical periods, on the evolution of the orogen as a whole, and in particular on the early convergence stage. By integrating results of OROGEN with those of other recent collaborative projects in the Pyrenean domain (e.g., PYRAMID, PYROPE, RGF-Pyrénées), this paper offers a synthesis of current knowledge and debate on the evolution of this immature orogen as recorded in the synorogenic basins and fold and thrust belts of both the upper European and lower Iberian plates. Expanding insight on the role of salt tectonics at local to regional scales is summarised and discussed. Uncertainties involved in data compilation across a whole orogen using different datasets are discussed, for example for deriving shortening values and distribution.
Comparison of the presence of ZIKV in Aedes sps. mosquitoes and ZIKV serum positives in humans between New Jersey, Florida, and Puerto Rico from 2015-2019

description: Across the course of time, finding ways to control insects and the destructive effects that they can cause has been a challenge for humankind. Diseases like the Zika virus canbe transmitted to humans via two common mosquitoes, Aedes aegypti (Linnaeus) and Aedes albopictus (Skuse); which are found in New Jersey, Florida, and Puerto Rico, Aedes mosquitoes facilitated the movement of the ZIKV pathogen from one tropical part of the world, Africa, to another, South America, later moving north to tropical US regions. This study included an analysis of Aedes aegypti and Aedes albopictus mosquitoes to determine if the virus has the capacity to survive in New Jersey, Florida, and Puerto Rico. The incidence of ZIKV in three different United States temperature zones were compared todetermine differences in the infection rate of ZIKV. This study explored ZIKV, its global movement and how the media affected the average person’s view of their risk of contracting this viral pathogen. Thus, requests for ZIKV testing of self-identified at-risk individuals were evaluated. Because ZIKV can cause a severe birth defect syndrome, the World Health Organization, declared ZIKV as a global pandemic in February 2016. The pandemic resulted in infants born with deformity across South America, the Caribbean and United States, including Florida and Puerto Rico.

description: The paper has reported the growth of vegetable sector in relation with technology mission, extent and determinants of marketed surplus and price spread of vegetables in the Kashmir valley. A substantial increase in the area and production of vegetables has been observed under Mini-Mission-II scheme of Technology Mission. At the farm level, vegetables have been observed to occupy an important place in the cropping pattern. The intensity of cropping in the study area has become more than 250 per cent due to multiple cropping of vegetable crops. On an average, producers’ marketed surplus has been found more than 92 per cent of the total production of selected vegetables. The estimates of regression function have revealed that the production, area under improved varieties, net price received by producers and education level are the significant and positive determinants of marketed surplus, while spoilage at farm level and consumption have shown a negative contribution. The price spread of vegetables with respect to various marketing channels has indicated that the producers’ share has an inverse relationship with the number of intermediaries. The net price received by the producers is relatively higher in the channels in which the produce is directly sold to the consumers or retailers. Across different vegetables, producers could receive higher absolute net returns in tomato, followed by brinjal and cauliflower in all the channels. The study has suggested that the coverage of technology mission should be expanded to other niche areas of vegetable cultivation. The study has also highlighted the needed effective measures to reduce marketing losses at various stages. Study has emphasized on the strengthening of institutions, establishment of processing units and development of market infrastructure in the area.

description: The cosmological electroweak phase transition can be strongly first order in extended particle physics models. To accurately predict the speed and shape of the bubble walls during such a transition, Boltzmann equations for the CP-even fluid perturbations must be solved. We point out that the equations usually adopted lead to unphysical behavior of the perturbations, for walls traveling close to or above the speed of sound in the plasma. This is an artifact that can be overcome by more carefully truncating the full Boltzmann equation. We present an improved set of fluid equations, suitable for studying the dynamics of both subsonic and supersonic walls, of interest for gravitational wave production and electroweak baryogenesis.

description: In India, annual production of pulses ranges from 11 Mt to 15 Mt, with yield of about 600 kg/ha. Due to the wide gap between supply and demand, import of pulses has increased from 0.38 Mt in 1993 to 2.82 Mt in 2008. Lentil is an important rabi pulse crop with a production of 0.85-0.95 Mt in India, after gram. The study has used both secondary and primary data collected from on-farm demonstrations and farmers’ fields to examine the ways to enhance the domestic supply of lentil. The study has found that there is a scope of increasing area under lentil during the rabi season, as its cost per hectare is less with higher net returns than the competing crops like wheat, gram and mustard in water-deficit and resource-poor conditions. There are large returns for adoption of disease management (80 per cent increase in net return), and improved small-seeded varieties (about 40 per cent increase in net return) in lentil. The study has found that lentil-based cropping systems are profitable and also have high water productivity, hence are suitable for mostly un-exploited rice-fallows under water-deficit conditions. Even though marketed surplus ratios have increased in recent years, there is a post-harvest loss to the extent of 7 per cent of production which needs to be curtailed to increase overall supply for final consumption. There is a case for larger institutional and policy support for pulse crops, keeping visible effects of pulse crops in increasing yield of subsequent crops in crop rotations.

description: Momentum resolved magneto-tunnelling spectroscopy is performed at a single sharp quantum Hall edge. We directly probe the structure of individual integer quantum Hall (QH) edge modes, and find that an epitaxially overgrown cleaved edge realizes the sharp edge limit, where the Chklovskii picture relevant for soft etched or gated edges is no longer valid. The Fermi wavevector in the probe quantum well probes the real-space position of the QH edge modes, and reveals inter-channel distances smaller than both the magnetic length and the Bohr radius. We quantitatively describe the lineshape of principal conductance peaks and deduce an edge filling factor from their position consistent with the bulk value. We observe features in the dispersion which are attributed to fluctuations in the ground energy of the quantum Hall system.

description: Short gamma-ray bursts (sGRBs) are generally thought to result from the merger of two neutron stars or the merger of a neutron star with a black hole. It is becoming standard practise to model these mergers with hydrodynamical simulations that employ equations of state that are derived, for example, for determining the behaviour of matter in core-collapse supernovae (CCSNe), and which therefore make use of the assumption that the matter is hot and in nuclear statistical equilibrium (NSE). In this Letter we draw attention to the fact that the hydrodynamical timescale (roughly the gravitational timescale of the neutron star) may be several orders of magnitude shorter than the timescale on which such equilibrium can be re-established in the tidal debris ejected during a sGRB, and that on the initial decompression timescales the unshocked tidal ejecta may remain sufficiently cool that the employed equations of state are not appropriate for modelling the dynamics of this part of the flow. On timescales short compared with the timescale on which NSE can be (re)established, the equation of state can remain relatively stiff and thus the stream of tidal debris can remain narrow and vulnerable to gravitational instability, as has recently been suggested. These findings suggest that estimates of the type and abundances of heavy elements formed in short gamma-ray bursts need to be revisited. We suggest that the most direct method of testing the physical and dynamical properties of tidal ejecta in sGRBs will come from modelling of their light curves, which provides the cleanest source of information on the system dynamics.

description: India is the largest producer and consumer of pulses in the world accounting for about 25 per cent of global production, 27 per cent of global consumption and about 33 per cent of the world’s area under pulses. However, compared to cereals like wheat and paddy, the growth rate of area and production of pulses is negligible and there exists wide variability in their yield in different states of country. The study has explored the growth and dynamics of production and consumption of major pulses in different states of India and has made a comparative evaluation of key economic factors affecting their production. Pulses have exhibited a grim picture in their production performance both spatially and temporally. Area substitution coupled with the biased revenue terms of trade has shown preference of cereals and oilseeds over pulses. However, pulses have been found to be preferred over coarse grains. Further, a structural shift in production performance of pulses-producing states not only validates the lack of spatial and temporal stability in their production performance but also throws light on the hidden potential of minor states in pulses production for long-term sustainability of pulse production.

description: Periodontal diseases are collection of several pathological conditions characterized by degeneration of gums, periodontal ligaments, alveolar bone, dental cementum, and migration of epithelium leading to the formation of periodontal pockets. Metastatic spread, metastatic injury, and metastatic inﬂammation are the three basic pathways linking oral infections to secondary systemic diseases. Metastatic spread of infection may occur from oral cavity to systemic circulation due to transient bacteremia. The study emphasizes on discussion about potential risk factors. Therefore, it is important to understand all possible risk-factors if morbidity and mortality due to this disease are to be reduced. Oral infection may represent a significant risk factor for systemic diseases, and hence the control of oral disease is essential for the prevention and management of these systemic conditions.

description: Albert Einstein postulated the equivalence of energy and mass, developed the theory of special relativity, explained the photoelectric effect, and described Brownian motion in five papers, all published in 1905, 100 years ago. With these papers, Einstein provided the framework for understanding modern astrophysical phenomena. Conversely, astrophysical observations provide one of the most effective means for testing Einstein's theories. Here, I review astrophysical advances precipitated by Einstein's insights, including gravitational redshifts, gravitational lensing, gravitational waves, the Lense-Thirring effect, and modern cosmology. A complete understanding of cosmology, from the earliest moments to the ultimate fate of the universe, will require developments in physics beyond Einstein, to a unified theory of gravity and quantum physics.

description: The study has been undertaken with the objectives of finding the extent of land degradation and its determinants in the mountainous regions of Himachal Pradesh by dividing the state into four zones. Multistage random sampling technique has been adopted to select the sample farmers from each zone. Logit analysis has been carried out to find the probability of different factors affecting land degradation. The factors whose effect on land degradation has been reported are: total owned land, land fragmentation, family labour, non-farm income, farm income, migration, leasing-out of land and education level of members in a household. The study has suggested some measures to minimize land degradation and consequently increase production and income levels in this difficult terrain of the country.

description: The specific heat of superfluid $^{3}$He, disordered by a silica aerogel, is found to have a sharp discontinuity marking the thermodynamic transition to superfluidity at a temperature reduced from that of bulk $^{3}$He. The magnitude of the discontinuity is also suppressed. This disorder effect can be understood from the Ginzburg-Landau theory which takes into account elastic quasiparticle scattering suppressing both the transition temperature and the amplitude of the order parameter. We infer that the limiting temperature dependence of the specific heat is linear at low temperatures in the disordered superfluid state, consistent with predictions of gapless excitations everywhere on the Fermi surface.

description: During butt welding of structural steels, an inhomogeneous material state across the weld occurs that has a detrimental influence on fatigue strength. In the presented study, the identification of Lemaitre Chaboche elastoviscoplastic model parameters is shown. The identification was conducted for base material, heat affected zone and filler material of submerged arc butt welded 1.8813 (S355MLO) structural steel. The derived constitutive model was integrated into a finite element simulation of the deep rolling process, which has not been investigated before for the post treatment of welded joints. Mechanical process loads were derived, giving first explanations of the deformation behavior.

description: The study conducted in the districts of Sonepat and Gurgaon in Haryana during the year 2003-04, has analysed the cost, returns and break-even point of mushroom production on different categories of farms, and has investigated the existing marketing system along with marketing cost, margins and marketing efficiency. Simple tabular analysis, benefit-cost analysis, break-even level, price spread and marketing efficiency have been used to draw the inference. The study has revealed that (i) the fixed capital investment is more than double in large and medium farms as compared to the small farms, (ii) the use of compost has a positive relationship with the farm size, (iii) there exists a positive relationship between mushroom production and farm size, (iv) large farmers have lowest cost of mushroom production as compared to small and medium farms due to efficient utilization of fixed farm resources, (v) the producer share in consumer rupee is highest in channel-IV, followed by channels II, III and I, respectively. The channel-I is the least efficient due to the existence of more middlemen. The study has suggested that (a) mushroom cultivation being capital-intensive, the financial assistance through institutional agencies at cheaper interest rate would be the desirable entity, (b) mushroom being a highly perishable crop and prone to high temperature, marketing infrastructures such as cold storage facilities are of immense importance. Similarly, suitable arrangements are needed by the canning/processing units for the management of surplus mushroom.

description: The study has analysed the technical efficiency in wheat production across different regions of the Punjab state. It is based on the cross sectional data collected from a random sample of 564 farm households comprising 58, 318, and 188 households from semi-hilly, central and south-western regions for the year 2005-06. The mean technical efficiency of wheat production has been found as 87 per cent, 94 per cent, 86 per cent and 87 per cent in semi-hilly, central, south-western and Punjab state as a whole, respectively. The results signify that farmers of the central region do not have much scope to increase productivity of wheat through technical efficiency improvement under the existing conditions of input-use and technology. In the semi-hilly and south-western regions, the yield of wheat can be improved to the extent of 13 per cent and 15 per cent, respectively through adoption of better practices of technology. Across different regions, wheat area has contributed positively and significantly, the coefficient being highest and only significant variable for the central region. The coefficient of expenditure on insecticides and pesticides has been found significant for the semi-hilly region, demanding boost in the expenditure on insecticides and pesticides to increase wheat production in this region. The coefficient of fertilizer nutrients has been observed positive and significant for the semi-hilly and south-western regions, indicating that there is scope for increasing production of wheat by enhancing the use of fertilizers in these regions. Further, the technical efficiencies are positively and significantly related to age, education and experience of a farmer and percentage area under the crop.

description: Entanglement has been termed a critical resource for quantum information processing and is thought to be the reason that certain quantum algorithms, such as Shor's factoring algorithm, can achieve exponentially better performance than their classical counterparts. The nature of this resource is still not fully understood: here we use numerical simulation to investigate how entanglement between register qubits varies as Shor's algorithm is run on a quantum computer. The shifting patterns in the entanglement are found to relate to the choice of basis for the quantum Fourier transform.

description: Successful aerial manipulation largely depends on how effectively a controller can tackle the coupling dynamic forces between the aerial vehicle and the manipulator. However, this control problem has remained largely unsolved as the existing control approaches either require precise knowledge of the aerial vehicle/manipulator inertial couplings, or neglect the state-dependent uncertainties especially arising during the interaction phase. This work proposes an adaptive control solution to overcome this long standing control challenge without any a priori knowledge of the coupling dynamic terms. Additionally, in contrast to the existing adaptive control solutions, the proposed control framework is modular, that is, it allows independent tuning of the adaptive gains for the vehicle position sub-dynamics, the vehicle attitude sub-dynamics, and the manipulator sub-dynamics. Stability of the closed loop under the proposed scheme is derived analytically, and real-time experiments validate the effectiveness of the proposed scheme over the state-of-the-art approaches.

description: Some metrological means, such as Shack-Hartmann, deflectometry sensors or fringe projection profilometry, measure the shape of an optical surface indirectly from slope measurements. Zonal shape reconstruction, a method to reconstruct shape with a high number of degrees of freedom, is used for all of these applications. It has risen in interest with the use of deflectometers for the acquisition of high resolution slope data for optical manufacturing, especially because shape reconstruction is limiting in terms of shape estimation error. Zonal reconstruction methods all rely on the choice of a data formation model, a basis on which the shape will be decomposed, and an estimator. In this paper, we first study the canonical Fried and Southwell models of the literature and analyze their limitations. We show that modeling the slope measurement by a point-wise derivative as they both do can induce a bias on the shape estimation, and that the bases on which the shape is decomposed are imposed because of this assumption. In the second part of this paper, we propose to build an unbiased model of the data formation, without constraints on the choice of the decomposition basis. We then compare these models to the canonical models of Fried and Southwell. Lastly, we perform a regularized MAP reconstruction, and compare the performance in terms of total shape error of this method to the state of the art for the Southwell and Fried models, first by simulation, then on experimental data. We demonstrate that the suggested method outperforms the canonical models in terms of total shape reconstruction error on a deflectometry measurement of the high-frequency content of a freeform mirror.

description: This SOP covers procedures for formatting, naming, and organizing 2D functional tissue unit (FTU) illustrations in Adobe Illustrator and linking their anatomical structures and cell types to relevant entities in the ASCT+B table.

The overall process of mapping FTU illustrations to ASCT+B tables involves the following steps:

selecting a 2D FTU illustration,

setting up the basic file structure,

separating cells by type to correspond with the ASCT+B table; and 

creating an SVG file and a crosswalk table.

The primary audience for this SOP is Indiana University project personnel who are creating crosswalk tables for FTUs in the Human Reference Atlas. Those who would like to understand how these crosswalk tables are constructed may also find this SOP of interest. This SOP assumes a basic working knowledge of Adobe Illustrator.

Scale-up of the perforated bipole trickle bed electrochemical reactor for the generation of alkaline peroxide
Creators: name: Gupta, Neeraj
Publisher: name: University of British Columbia
Year: 2009

description: Conventional electrochemical reactors generating alkaline hydrogen peroxide by electro-reduction of oxygen use three-dimensional electrodes in mono-polar cell stacks that operate near atmospheric pressure. The available commercial electrochemical process (eg. the Dow-Huron trickle-bed cathode) is limited to a current density of about 1 kA m-², while other systems under development (eg. the Kvaerner-Chemetics gas diffusion cathode) run at current density up to about 2 kA m-². This relatively low current density results in a high capital cost that limits the use of the electrochemical process as an alternative to the commercial thermochemical process that obtains hydrogen peroxide by the auto-oxidation of anthraquinols. The limitations to the current density in the electrochemical processes operating near atmospheric pressure are largely due to oxygen mass transfer constraints. To increase the oxygen mass transfer rate work has been done at UBC with a bipolar electrochemical reactor that runs at 800-1200 kPa. As opposed to other systems the UBC process uses a relatively simple cell configuration in which a single electrolyte flows with oxygen gas in a graphite felt cathode, sandwiched between a microporous diaphragm and a bipolar electrode plate. To compete with the commercial thermochemical process such an electrochemical reactor should operate with good current efficiency and low voltage (e.g. > 80 %, < 3 Volt) at current densities above 3 kA m-². The anodic generation of oxygen in the UBC system at current density above ca. 2 kA m-² is a problem as it inhibits the passage of current and compromises the performance of the reactor. To circumvent this problem of anode resistance experimental work was done on a perforated bipole electrochemical reactor that allows oxygen disengagement on the anodes through the perforations into the adjacent cathode bed. These perforations also allow current by-pass that translates in to a loss in current efficiency. As a guide to the development and scale-up of this system a two-cell bipolar electrochemical reactor was modelled with trickle-bed cathodes and the current by-pass through the perforated bipole accounted for. The predictions of this model were compared to the performance of a bench scale reactor operating at current density up to 5 kA m-² and used to optimize the bipole configuration. The reactor was eventually scaled-up from small scale (120 mm length by 25mm width and superficial electrode area 30e-4 m² ) to medium scale (630 mm length by 40 mm width and superficial electrode area 200e-4 m2) for two cells. The current efficiency for peroxide generation on the two-cell medium scale reactor was very encouraging (~ 80% at 5 kA m-²) and the voltages obtained were also in the desired range (~ 3.2 V per cell at 5 kA m-²).

description: For idealized (spherical, smooth) dark matter halos described by single-parameter density profiles (such as the NFW profile) there exists a one-to-one mapping between the energy of the halo and the scale radius of its density profile. The energy therefore uniquely determines the concentration parameter of such halos. We exploit this fact to predict the concentrations of dark matter halos via a random walk in halo energy space. Given a full merger tree for a halo, the total internal energy of each halo in that tree is determined by summing the internal and orbital energies of progenitor halos. We show that, when calibrated, this model can accurately reproduce the mean of the concentration--mass relation measured in N-body simulations, and reproduces more of the scatter in that relation than previous models. We further test this model by examining both the autocorrelation of scale radii across time, and the correlations between halo concentration and spin, and comparing to results measured from cosmological N-body simulations. In both cases we find that our model closely matches the N-body results. Our model is implemented within the open source Galacticus toolkit.

description: Citations play a vital role in understanding the impact of scientific literature. Generally, citations are analyzed quantitatively whereas qualitative analysis of citations can reveal deeper insights into the impact of a scientific artifact in the community. Therefore, citation impact analysis (which includes sentiment and intent classification) enables us to quantify the quality of the citations which can eventually assist us in the estimation of ranking and impact. The contribution of this paper is two-fold. First, we benchmark the well-known language models like BERT and ALBERT along with several popular networks for both tasks of sentiment and intent classification. Second, we provide ImpactCite, which is XLNet-based method for citation impact analysis. All evaluations are performed on a set of publicly available citation analysis datasets. Evaluation results reveal that ImpactCite achieves a new state-of-the-art performance for both citation intent and sentiment classification by outperforming the existing approaches by 3.44% and 1.33% in F1-score. Therefore, we emphasize ImpactCite (XLNet-based solution) for both tasks to better understand the impact of a citation. Additional efforts have been performed to come up with CSC-Clean corpus, which is a clean and reliable dataset for citation sentiment classification.

description: Semiconductor quantum-dot spin qubits are a promising platform for quantum computation, because they are scalable and possess long coherence times. In order to realize this full potential, however, high-fidelity information transfer mechanisms are required for quantum error correction and efficient algorithms. Here, we present evidence of adiabatic quantum-state transfer in a chain of semiconductor quantum-dot electron spins. By adiabatically modifying exchange couplings, we transfer single- and two-spin states between distant electrons in less than 127 ns. We also show that this method can be cascaded for spin-state transfer in long spin chains. Based on simulations, we estimate that the probability to correctly transfer single-spin eigenstates and two-spin singlet states can exceed 0.95 for the experimental parameters studied here. In the future, state and process tomography will be required to verify the transfer of arbitrary single qubit states with a fidelity exceeding the classical bound. Adiabatic quantum-state transfer is robust to noise and pulse-timing errors. This method will be useful for initialization, state distribution, and readout in large spin-qubit arrays for gate-based quantum computing. It also opens up the possibility of universal adiabatic quantum computing in semiconductor quantum-dot spin qubits.

description: Understanding the complex phase diagram of cuprate superconductors is an outstanding challenge. The most actively studied questions surround the nature of the pseudogap and strange metal states and their relationship to superconductivity. In contrast, there is general agreement that the low energy physics of the Mott insulating parent state is well captured by a two-dimensional spin $S$ = 1/2 antiferromagnetic (AFM) Heisenberg model. However, recent observations of a large thermal Hall conductivity in several parent cuprates appear to defy this simple model and suggest proximity to a magneto-chiral state that breaks all mirror planes perpendicular to the CuO$_2$ layers. Here we use optical second harmonic generation to directly resolve the point group symmetries of the model parent cuprate Sr$_2$CuO$_2$Cl$_2$. We report evidence of an order parameter $Φ$ that breaks all perpendicular mirror planes and is consistent with a magneto-chiral state in zero magnetic field. Although $Φ$ is clearly coupled to the AFM order parameter, we are unable to realize its time-reversed partner ($-Φ$) by thermal cycling through the AFM transition temperature ($T_{\textrm{N}}$ $\approx$ 260 K) or by sampling different spatial locations. This suggests that $Φ$ onsets above $T_{\textrm{N}}$ and may be relevant to the mechanism of pseudogap formation.
