title: Microbiome analysis and random forest algorithm-aided identification of the diacetyl-producing microorganisms in the stacking fermentation stage of <i>Maotai-</i>flavor liquor production

description: Diacetyl imparts a characteristic buttery aroma to foods and beverages. However, when present at high levels in <i>Maotai</i>-flavor liquor, it generates an undesirable buttery off-odor. The aim of this study was to identify the diacetyl-producing microorganisms in <i>Maotai</i>-flavor liquor with an ultimate aim to develop methods that could reduce diacetyl production. To explore the microbial origin of diacetyl in <i>Maotai</i>-flavor liquor, the off-odor intensity and diacetyl content of stacking fermented grains, which are used in the production of <i>Maotai</i>-flavor liquor, were evaluated. Then, 16S rRNA V3-V4 high-throughput sequencing and the random forest algorithm were combined to analyze the potential diacetyl producers. The featured selection results indicated that <i>Lactobacillus</i> was the major diacetyl contributor in the fermented grains, followed by <i>Staphylococcus, Weissella, Pediococcus</i>, and <i>Klebsiella</i>. To verify this, 123 lactic acid bacteria (LAB) isolates were selected from the high diacetyl off-odor group samples, and the genus <i>Lactobacillus</i> accounted for more than 90% of the identified isolates. The results of our study showed that <i>L. plantarum, L. pentosus</i>, and <i>L. fermentum</i> were the major diacetyl-producing microorganisms (&gt;90 mg/L). Moreover, the fermentation characteristics of the high-yield strain, <i>L. plantarum</i> MTL-09, showed that temperature and pH had strong effects on diacetyl production, which may offer a strategy for inhibiting the off-odor by controlling the pH or temperature during fermentation. The methods may also be useful for identification of key microorganisms for fermented foods and alcoholic beverages.

title: Austrian Crystallographic Diffraction Consortium

description: The Austrian Crystallographic Diffraction Consortium (ACDC) BAG aims at supporting several macromolecular structural biology groups across Austria (in total 20 research groups at 9 institutions in 4 cities). We employ mainly the technique of X-ray crystallography to characterize macromolecular biological complexes, but also solution scattering approaches are frequently used to characterize dynamic assemblies. Approval of this BAG will be essential for researchers in all our groups to carry out their structural studies on various health-related and basic research-oriented topics, which are targeted at characterizing large molecular assemblies or proteins currently under-represented in the PDB, including membrane proteins. Corresponding high-resolution diffraction data are only obtainable through the use of synchrotron radiation sources. Thus regular synchrotron access is highly desirable to maintain a competitive advantage in our individual research fields.

title: Molecular machines in energy transduction, cellular signaling and defense processes

description: Since this BAG is composed of seven different working groups from three different locations (university of Cologne, university of Bochum, university of Düsseldorf), the projects for this proposal are of rather heterogeneous nature. Nonetheless, we are focusing on 5 main topics:
1.) proteins involved in transport processes, transporters or channels, either embedded in the membrane or acting in the cytosol (e.g. ABC transporters, fusion proteins, regulators)
2.) proteins involved in the immune system, pathogen invasion or defense/resistance processes (dehydratases, toxins, binding proteins)
3.) proteins involved or associated with diseases like cancer or developmental disorders (e.g. protein kinase, toxins, antibodies)
4.) enzymes of putative industrial use to encounter increasing environmental pollution (e.g. transaminases, estereases)
5.) proteins involved in light harvesting, photosynthesis (C3/C4 pathways) and chromophore binding proteins (e.g. synthases, photosensor domains)

title: Shedding light on the microbial dark matter with photons from Synchrotron radiation: structural biology of mesocosms by an explorative pipel

description: The microbial world is constantly shaping the planet by governing the carbon, nitrogen, and sulfur cycles. While recent developments in ¿omics¿ opened a window of the complexity of this world, it is still problematic to attribute a function to a gene product or predict enzymatic reactions simply from its sequence. Then, how can enzymes be studied from uncultivated microbes? In this proposal, we are using an explorative approach to open a new field: the structural elucidation of catabolic enzymes from microbial mesocosms. We will study two models, an anaerobic bioreactor containing a methane-degrading consortium, and a microbial community from wastewater treatment. As a proof of concept, we recently isolated, crystallized, and structurally characterized the methane-generating enzyme from an archaeon living in this activated sludge. Now, we will go beyond and isolate more enzymes of catabolic pathways from these "microbial dark matter", playing a key role in the carbon cycle.

title: SAXS studies of radiation damages induced in protein complexes with Cu(II) and Zn(II) cations

description: The aim of this research project is to determine the influence of synchrotron radiation on the induction of radiation damage in selected model protein structures in the presence of copper, zinc and other divalent metal ions. Human serum albumin (HSA) and human cystatin C (HCC) were selected as model systems, which were previously examined using X-ray absorption spectroscopy (XAS) in complexes mainly with Cu(II) and Zn(II) cations. The analysis using the bioSAXS technique will determine potential structural changes and correlates them with radiation damages visible in XAS studies.

title: Supported lipid bilayers (SLBs) challenged by nano-ions

description: Nano-ions such as polyoxometalates (POMs), boron clusters and hydrophobic ions, are nanometric ionic molecules with unique architecture and super-chaotropic properties. Despite nano-ions promising membrane-targeting ability, direct evidence of the proposed mechanism based on the formation and desorption of POM-lipid assemblies is lacking. Following our SANS study of interactions between nano-ions with mixed 1,2-dioleoyl-sn-glycero-3-phosphocholine (DOPC)/ 1,2-dioleoyl-3-trimethylammonium-propane (DOTAP) at ISIS Larmor, and XRR study at Diamond I07 of the nano-ion interactions with the DOPC/DOTAP Langmuir monolayer at the air-water interface, we propose a comprehensive XRR study to examine in detail the structural changes of supported lipid bilayers (SLBs) mediated by nano-ions, as a function of lipid composition, type of nano-ions, concentrations, and temperature. This will enable Dr Wlodek to successfully complete her H2020 Marie Curie Fellowship project.

title: Synthesis of novel superhard B-C-N materials under high pressure and high temperature

description: The possibility to synthesize superhard materials from the light elements B, C, and N has attracted significant attention during the last century. Indeed, these elements can form multiple short and strong covalent bonds, thereby often displaying very high shear and bulk moduli (B0), both essential for achieving superhardness (Hv&gt;40 GPa). The experimental studies have investigated only a small fraction of the chemical phase space—largely restricted to the binary systems—and pressure space, most often limited below 30 GPa. Therefore, the aim of this proposal is to investigate the B-C-N system up to pressures and temperatures of 130 GPa and 3000 K, in an effort to produce novel solids with remarkable properties. The new compounds’ crystal structure, along with their stability range and bulk modulus, will be determined using single-crystal X-ray diffraction of polycrystalline samples. This proposal directly builds on top of our recent successes with the C-N system.

title: Unraveling the Role of Secondary Phases in Optical Behavior of Hybrid Semiconductor Nanowire Architectures

description: Hybrid semiconductor nanowire architectures are crucial building blocks for novel optoelectronic nanodevices. Recently, we have demonstrated the critical role of secondary phases in the optical response of Zn doped Sn1-xGexO2 crystallites on Zn2GeO4 nanowires. In particular, our findings suggest a connection between the Zn impurities, the formation of a secondary phase and the asymmetrically distributed UV emission. However, a full understanding of the origin of this phase segregation is still lacking. This proposal aims to use scanning X-ray diffraction microscopy at the ID01 beamline to analyze the secondary phase formation and the strain distribution in these hybrid architectures in order to clarify the mechanisms behind the radiative transitions in these hybrid architectures

title: High-Entropy Hydride Prepared by Direct Conversion of Cantor Alloy under High-pressure High-temperature

description: We are going to explore reactions of fcc–CoCrFeNiMn high-entropy alloy (co-called Cantor alloy) with hydrogen under high-pressure and especially high-temperature to access high-entropy hydrides. According to our previous laser heating LVP experiments, Cantor alloy does not form hydride at room temperature under compression with hydrogen. Further heating results in the formation fcc–CoCrFeNiMnH high-entropy hydride. In situ data under moderate temperatures will allow us to build complete P–T–x phase diagrams and find conditions to transform high-entropy alloys into high-entropy hydrides.

title: Metal Organic Frameworks for CO2 capture: understanding the role of defective sites and pores functionalization with a combined structural a

description: Defective sites in metal-organic frameworks (MOFs) have a great impact on the performance of CO2 capture, the mechanism of which changes depending on the type and nature of these defects found at the metal sites. However, a detailed mechanistic, structural, and electronic understanding of the adsorption-desorption process over defective sites in amine-functionalized MOFs, known in the literature as highly performing CO2 capture porous materials, is lacking. Here we propose a combined in situ hard-X-ray XAS and XRD study targeting metal sites and MOFs pores to gain a structural and electronic understanding of CO2 adsorption over defective sites on a series of amino-tagged Fe(III) pyrazolate-based MOFs. We expect our spectroscopic and structural results to unveil the stages of CO2 capture over defective sites and functionalized pores with unprecedented structural detail, thereby paving the way for the rational design of improved MOF materials for CO2 adsorption and separation.
