Utilization of vetiver grass containing metals as lignocellulosic raw materials for bioethanol production

Abstract This study deals with bioethanol production from vetiver leaves contaminated with heavy metal ions, Al(iii) and Ni(ii). The effects of these ions on the growth of Neurospora intermedia and the production of bioethanol from vetiver leaves were investigated. The bioethanol production was carried out by a simultaneous saccharification and fermentation (SSF) method in submerged culture using N. intermedia. The SSF was operated micro-aerobically for 72 h. In order to enhance the bioethanol production, fermentation was anaerobically continued for more 72 h. The growth of N. intermedia was not affected by the presence of Al in a concentration range of 5–80 ppm. However, the growth rate of N. intermedia increased when the culture medium also contained 1 ppm Ni(ii). The highest growth rate (0.031 h−1) was achieved when the culture medium contained 10 ppm Al(iii) and 1 ppm Ni(ii). The higher the Al(iii) concentration contained in the culture medium, the lower the bioethanol yield. On the other hand, the presence of 1 ppm Ni(ii) in the medium along with Al(iii) increased the bioethanol yield. Vetiver leaves contaminated with 10 ppm Al(iii) and 1 ppm Ni(ii) can potentially be used as a substrate for bioethanol production.

Isolation and evaluation of xylose-fermenting thermotolerant yeasts for bioethanol production

Abstract Three thermotolerant yeasts capable of producing more than 7 g/L of ethanol from 30 g/L xylose were isolated. Molecular identification using ribosomal DNA internal transcribed spacer showed that isolates Pa27 and Pi131 were strains of Pichia kudriavzevii while Ma9 was a strain of Candida tropicalis. Under optimal conditions, Pa27, Ma9 and Pi131 produced maximum ethanol yields (g ethanol/g xylose) of 0.35 ± 0.002, 0.35 ± 0.007 and 0.39 ± 0.002, respectively. At a fermentation temperature of 42 °C, the maximum ethanol yields (g ethanol/g xylose) were 0.21 ± 0.005, 0.22 ± 0.005 and 0.23 ± 0.006 after 96 hours for Pa27, Ma9 and Pi131, respectively. The isolates co-fermented glucose and xylose to ethanol, and the presence of a small amount of glucose improved the xylose utilization rate. Pa27 was the best strain for fermentation of a mixture of xylose and glucose. At the optimum ratio of glucose to xylose (4:6 to 5:5), ethanol yield by Pa27 decreased from 0.43 to 0.35 when the temperature was increased from 30 to 42 °C. It is notable that even at 42 °C, all the three isolates fermented a mixture of xylose and glucose with ethanol yields higher than 0.33 g ethanol/g sugar.
Post-Harvest Warehouse Management for Actinidia arguta Fruits

It is well-recognized that storage practices can widely infl uence the quality of fruits in the post-harvest chain [Wang et al., 2015]. The research plays an important role, especially for new fruit cultivars, including Actinidia arguta (Siebold et Zucc.) Planch. ex Miq. Among fresh and perishable fruits, the baby kiwifruits are consumed without peeling, similarly to berries. Due to the rapid transformation to softening, skin wrinkling, water loss and fruit decay [Latocha et al., 2014], baby kiwifruits require effi cient storage tools in the supply chain management [Giuggioli et al., 2017; White et al., 2005]. When compared to other Actinidiaceae (A. deliciosa, and A. chinensis), the baby kiwifruit can be stored for a shorter period of time, namely for 1–2 months at 0°C [Baudino et al., 2017; Lim et al., 2016; Strik & Hummer, 2006]. Previous studies have attempted to identify the best method for increasing the shelf-life, by utilizing 1-methylcyclopropene (1-MCP) [Wang et al., 2015], edible coating [Fisk et al., 2008; Kaya et al., 2016] or by identifying the optimal harvest date for improving storability [Oh et al., 2017]. According to the current social and economic scenarios, the driver of the innovation and the key point to improve the performance of all preserving techniques is the sustainability requirement to satisfy the competitiveness asset of the supply chain. In addition, it is reported that some storage methods involving the management of the atmosphere in the storage room (controlled atmosphere) are more expensive when compared to other tools [Wang et al., 2015]. The warehouse storage represents a critical point in the fresh fruit supply chain
Empowering Aboriginal Families as Their Children’s First Teachers of Cultural Knowledge, Languages and Identity at Galiwin’ku FaFT Playgroup

Embracing and embedding the rich cultural knowledge, languages, concepts and skills that Aboriginal families and children bring to playgroup is key to empowering families as their children’s first teachers and strengthening young children’s self-esteem, pride, confidence and identities. In this article, we share our story of how we have explored and upheld the strengths of Yolŋu identity, cultural knowledge and language in the Galiwin’ku Families as First Teachers (FaFT) playgroup early educational program. We highlight the ways we have supported mothers to embed gesture, sign language, Yolngu Matha language conventions, Yolŋu kinship, clan concepts and dance into their daily interactions with their children at FaFT. We reflect on what has empowered mothers to feel agentic in their children’s learning in these playgroups and to build strong Yolŋu identities in young children and argue that playgroup is a vital educational platform through which to deliver culturally meaningful early learning experiences for Aboriginal children prior to preschool.
Secondary Cytoreductive Surgery in Platinum-Sensitive Recurrent Ovarian Cancer: A Meta-Analysis

PURPOSE The survival impact of secondary cytoreductive surgery in patients with platinum-sensitive recurrent ovarian cancer was studied. METHODS We identified published studies from 1983 to 2021 following our inclusion criteria from MEDLINE, EMBASE, and Cochrane library. To integrate the effect size of single-arm studies, meta-analysis was performed using death rate as a primary outcome. The effect of complete cytoreduction and optimal cytoreduction on survival was evaluated using meta-regression. The pooled death rate was presented with a 95% CI. The publication bias was evaluated with the funnel plot and Egger's test, and sensitivity analysis was performed. To overcome missing death rates, the linear regression model was performed on log-transformed median overall survival (OS) time using study size as a weight. RESULTS Thirty-six studies with 2,805 patients reporting death rates were used for this meta-analysis of the 80 eligible studies. There was strong heterogeneity, with the P value of the Cochrane Q test of < 0.0001 and Higgins's I2 statistics of 86%; thus, we considered a random effect model. The pooled death rate was 44.2% (95% CI, 39.0 to 49.5), and both the complete and optimal cytoreductions were associated with better survival outcomes as significant moderators in the meta-regression model (P < .001 and P = .005, respectively). Although 14 studies were located outside the funnel plot, Egger's test indicated no publication bias (P = .327). A sensitivity analysis excluding 14 studies showed similar results. In the linear regression model on the basis of 57 studies, the median OS time increased by 8.97% and 7.04% when the complete and optimal cytoreduction proportion increased by 10%, respectively, after adjusting other variables. CONCLUSION Secondary cytoreductive surgery, resulting in maximal tumor resection, significantly prolongs OS in platinum-sensitive recurrent ovarian cancer. This study is to evaluate the survival impact of secondary cytoreductive surgery in patients with platinum-sensitive recurrent ovarian cancer. It contains 36 studies for meta-analysis and 57 studies for meta-regression and, to our knowledge, is the largest to date. In the meta-analysis, the complete cytoreductions were associated with better survival outcomes. In the linear regression model, the median overall survival time increased by 8.97% when the proportion of complete cytoreduction increased by 10%. Secondary cytoreductive surgery with maximal tumor resection increased significantly overall survival in platinum-sensitive recurrent ovarian cancer.
Are Political Factors More Relevant Than Economic Factors in Firm-Level Renewable Energy Technology Export? Evidence from Path Analysis

Renewable energy technology (RET) firms are key economic entities in the export of RET-related products and components, in which RET firms’ exports are affected largely by policy and market. Nonetheless, the effects of policy and market factors on RET firm-level export have never received attention from researchers. This study aims to fill the gap by taking a political economy approach to establish a structural equation model to analyze the path of political-economic factor-firms’ market orientation-based export. This study reveals that RET firms’ market-orientation-based export enhancement depends entirely on political forces. Particularly, two government intervention instruments, environmental policy and export promotion policy, were highlighted. However, the effects of renewable energy policies on the exports of RET firms through market orientation are negative and statistically significant. This study proves that the effects of inter-firm competition and market attractiveness on RET firms’ exports through their market orientation are negative and statistically significant and insignificant, respectively. Further, this study demonstrates that RET firms’ market orientation has a significant positive effect on their export performance. We conclude that in order to improve RET-related policy effectiveness and efficiency, it will be useful to consider firms’ heterogeneity in response to external factors. Additionally, a full mediation model in the academic investigation of the effects of various external factors, including public policies and market factors, on firm-level export, and the implementation of firm-level export-induced policy, taking into account firms’ managerial interpretations to external factors, should be considered.
Determination of Some Selected Heavy Metals in Water, Oreochromis niloticus and Labeobarbus intermedius Samples from Abaya and Chamo Lakes

The fish organs and water was collected from three sampling sites of Lakes Chamo and Abaya. A procedure consuming 12 mL mixture of HNO 3 -H 2 O 2 for gill, kidney, liver and 1:2.5 mL mixture of HNO 3 -HCl for water samples for digestion of was developed. Concentrations of six metals in water and their accumulation in the edible tissue of Tilapia (Oreochromis niloticus) and Barbus (Labeobarbus intermedius) fish species were determined using Flame Atomic Absorption Spectroscopy. The results revealed that the average heavy metal concentrations in water samples were; Zn 0.017, Cu 0.077, Fe 7.50, Cr 0.033, Cd 0.264 and Pb 1.731 mg/L respectivelty. The highest concentrations of iron (Fe) and lead (Pb) were observed at Chamo Park and Sile sites, respectively. The average contents of heavy metals in fish samples were; Zn 0.062, Cu 0.047, Fe 2.270, Cr 0.041, Cd 0.045 and Pb1.78 mg/Kg in both fish species. The highest accumulations of iron (Fe) and lead (Pb) concentration were observed in liver and gill of Tilapia fish from Chamo Lake. There was no significant difference between the two lakes in accumulating trace metals. Keywords : Fish variety, Heavy metals, Lakes, ANOVA
Research Study of the Conditions of Wastes Lipolysis Lipid Fraction

Biotechnological processing of secondary raw material resources of the oil and fat industry in useful products is the most expedient and effective in terms of both economic and environmental requirements. The obtained experimental results of the study indicate the prospect of lipolysis with the lipase Rhizopus japonicus fat fraction of waste generated during the hydrogenation of vegetable oils. The greatest activity in relation to olive oil is expressed by lipase Rhizopus oryzae. Lipase Rhizopus japonicus exhibits the highest activity relative to hydrogenated fat, which is explained by its substrate specificity. It was found that the content of free fatty acids in the hydrolyzate reached the saturation level after 72 hours of hydrolysis, and the concentration of triglycerides during this time of hydrolysis decreased to a minimum value. The results of research should be used to improve the processing technology of waste oil and fat industry in the food industry.
Development of an electronic aerosol atomisation system for generating three-dimensional (3D) cells in microencapsulations and microtissues characterisation

Cell encapsulation is a micro technology widely applied in cell and tissue engineering, tissue transplantation and regenerative medicine. Various techniques had been developed for microencapsulation of cells but these techniques presented threat to the cells due to the harsh or chemical treatment applied. In this research, a simple and economic electronic aerosol atomisation system was proposed for producing calcium alginate microcapsules. The system was developed with the incorporation of a conventional syringe pump, a customised air pump and motor controller circuits. The microcapsules and 3D microtissues were biophysically characterised. For the output of the system, the microcapsules size slightly increased with the extrusion rates and decreased significantly with the airflow rates. At an extrusion rate of 20 μl/min and airflow rate of 0.3 l/min, microcapsules with a diameter ranging from 220 - 270 μm were generated. The polymerisation time for the microcapsules was approximately 10 minutes after the immersion in calcium chloride solutions. The microcapsules showed high porous surface structure in field emission-scanning electron microscopy (FE-SEM) imaging. Keratinocytes (HaCaT) and Oral Squamous Cell Carcinoma (ORL-48) cells at cell densities of 3 × 107 and 9 × 107 cells/ml, respectively were applied for encapsulation and successfully grew into microtissues after 16 days of culture. The fourier transform infrared (FTIR) spectroscopy of the 3D cells showed stretching in phosphate bond of Deoxyribonucleic acid (DNA) and Ribonucleic acid (RNA) backbone, lipid and protein. The cells of HaCaT and ORL-48 microtissues were viable and they were characterised by different nucleus size. Replating experiment demonstrated that the cells in the microtissues could spread and proliferate in the culture dish. The electronic aerosol atomisation system developed in this work has successfully produced microcapsules with controllable size and applicable for growing microtissues. The microtissues produced are potentially a useful cell model for the study of cytochemicals.
SULFONATION OF STYRENE - ALLYL GLYCIDYL ETHER COPOLYMERS

Sulfonated polymeric materials are widely applied in the development of high-performance proton-conducting membranes. In terms of sulphating agents, concentrated sulphuric- and chlorosulfonic acids, a mixture of methanesulfonic- and concentrated sulphuric acid, and acetyl sulphate are most commonly used. A high degree of sulfonation of membrane materials provides efficient proton transport and excellent current-voltage characteristics of fuel cells. In order to develop a new proton-conducting membrane, the sulfonation of copolymers of styrene and allyl glycidyl ether is carried out, the composition and structure were confirmed by elemental analysis, IR and NMR spectroscopy. Obtained copolymers represent powdery substances, having a cream to dark brown colour, and are characterised by good solubility in benzene and acetone. The degree of sulfonation varies from 12 to 98 mol. %. Additionally, a quantum chemical study of the sulfonation mechanism of styrene and allyl glycidyl ether copolymers is studied using Gaussian 09 software; MP2//B3LYP level of theory and 6-311++G(d,p) basis set and composite CBS-QB3 method. Studying the process of copolymers sulfonation and comparing the obtained results with the data of quantum chemical calculations is essential for the development of additional methods for obtaining effective proton-conducting membranes.

Mat lab software employing Fresnel formula for a layer system was used in data analysis. The sensor ranged linearly from 1 to 10 ppb. The SPR curves for the Au / Fe2H2O4-GO with different percentages of graphene oxide GO to Fe2H2O4 (1:10 % (v/v)) respectively were attached separately the prism. The results show that when the films with 3% GO which can be observed as the optimum percentage enhancement of sensitivity for detecting ions from 0.0773°ppb−1 for Au/Fe2H2O4 to 0.2509° ppb−1 for Au / Fe2H2O4-GO. With a limit of detection 0.6 μg/L fulfills the detection requirement below the 10 and 5μg/L contaminant levels of Arsenic as suggested by World Health Organization (WHO) and Environmental Protection Agency (EPA). The analytical method was verified by linearity, detection limits, precision, accuracy, and recovery experiments, achieved acceptable results in all states.
A miniaturized clark oxygen sensor for organ-on-chip devices

Oxygen concentration is an essential regulatory parameter in cell culture and organ-on-chip devices. Measuring variations in oxygen concentration near cells during cell culture can provide a wealth of information on cell viability, cellular activity, cell differentiation and response to external stimuli. Here, we present a miniaturized three-electrode Clark oxygen sensor, which is shown to be biocompatible, protected from biofouling and has a 7.5s response time. This miniaturized sensor allows to measure the oxygen concentration in a microfluidic channel of an organ-on-chip, whereby this chemical microenvironment can be monitored.
Biochemical changes associated with elevated carbon dioxide in rice (Oryza sativa L.)

The environmental change has tremendous effect in crop production in the form of increased stress all through the plant growth and development. Consequently the aim of the investigation was to assess the effect of elevated carbon dioxide under artificially induced carbon dioxide condition utilizing an open top chamber with rice genotype CO 51. Rice could provide less protein, nutrients and minerals fundamental for humans be in response to rising carbon dioxide concentrations that are involved in global warming. Increased concentrations of atmospheric carbon dioxide are anticipated to decrease the content of fundamental component, for example, protein in rice, threatening the nutrition of billions of people in the middle of the century. However, changes in plant-based nutrient substance in response to carbon dioxide have not been elucidated. The results from the present investigation revealed that the increased carbon dioxide have negative effects on soluble protein content (mg g-1) and nitrate reductase activity (µmol NO2 g-l hr-1) and positive effects on sucrose phosphate synthase (µ mol mg-1 protein min-1) and starch content (mg g-1) in different crop developing stages.
Populus ciliata mediated synthesis of copper oxide nanoparticles for potential biological applications

The copper oxide nanoparticles (CuO NPs) have been successfully synthesized using the leaf extract of Populus ciliata (P. ciliata) as capping and stabilizing agent. The crystalline nature of CuO NPs was confirmed by x-ray diffraction (XRD) while the morphological study was conducted by performing Scanning Electron Microscopy (SEM) and Transmission Electron Microscopy (TEM). The percent composition and purity was examined by using energy dispersive x-ray (EDX) while fourier transform infrared (FTIR) spectroscopy was used to study surface functional groups. The copper oxide nanoparticles (CuO NPs) were tested against Gram positive bacteria; Staphylococcus aureus (S. aureus) Staphylococcus pyogenes (S. aureus) and Gram negative bacteria; Escherichia coli (E. coli), Pseudomonas aeruginosa (P. aeruginosa) and Klebsiella pneumoniae (K. pneumoniae) for its antibacterial activity. The antibacterial activity was increased with increasing concentration of the CuO NPs. A higher activity was found against Gram negative bacteria as compared to Gram positive bacteria.
