Summary: Yeasts were isolated from potential sources and tested for ethanol tolerance and fermentation performance. Among 27 isolates, only five showed high ethanol tolerance and production efficiency, with SSJ01KKU performing the best under all conditions. Molecular taxonomic analysis revealed SSJ01KKU as S. cerevisiae and the other four isolates as Pichia caribbica.

Summary: This study evaluates the potential of natural and industrial strains of Saccharomyces cerevisiae to secrete cellulases. The results show that natural isolates have better secretion capacities for cellulases under high temperature and acetic acid conditions, and exhibit tolerance to various fermentation-associated stresses. These isolates could serve as promising chassis organisms for consolidated bioprocessing bioethanol production.

Summary: Vanillin is an important phenolic inhibitor in Saccharomyces cerevisiae, inhibiting the translation process. Deletion of YRR1 enhances vanillin resistance by promoting translation-related processes. Proteomic changes induced by vanillin stress and YRR1 deletion provide insights into yeast's protective response to vanillin.

Summary: The large consumption of non-renewable fossil fuels has led to energy depletion and environmental pollution, necessitating the production of renewable biofuels as an effective alternative to alleviate the energy crisis. Saccharomyces cerevisiae, as an ideal type of biofuel, has gained attention for its high efficiency in bioethanol synthesis. This study provides a systematic summary of the advantages of S. cerevisiae in biosynthesis, discusses research strategies and existing bottlenecks, and proposes reasonable prospects for its bioethanol synthesis.

Summary: This study investigated the relationship between wild type and engineered strains of the same microorganism in terms of kinetic parameters, and proposed a set of correction factors to estimate kinetic constant values for species or strains for which they are not available. The results showed a correlation between wild type and engineered strains, with specific substrate limitation constants being higher in the engineered strains. These correction factors were found to be conserved and could serve as a guide for estimating kinetic constants in other species or strains.

Summary: Microbial ecology in an agricultural ecosystem influences grapevine health, crop production, and wine aroma and flavor formation. Geographic origin and grape variety significantly influence the differentiation of fungi, yeasts, and Saccharomyces cerevisiae during fermentation, ultimately shaping the wine aroma profiles. The geographic distribution of microbial communities suggests that fermentative yeast can be distinct in a local setting, with implications for sustainable agricultural practices and beverage quality.

Summary: The development of glucose/xylose co-fermenting Saccharomyces cerevisiae strain capable of co-producing polyhydroxybutyrate has improved the bioethanol yield from lignocellulosic biomass. This study demonstrates the feasibility of co-production of bioethanol and value-added chemicals to maximize the values derived from lignocellulosic biomass, using various types of biomasses.

Summary: Research has shown that wines and vinegars produced through different fermentation methods have varying pH levels, total acidity, soluble solids, and concentrations of specific compounds such as phenolic acids and malic acid. The selection of different fermenting agents can have a significant impact on the composition of the final product, with some combinations resulting in higher levels of certain acids and compounds. The choice of acetic acid bacteria for acetous fermentation may need to be reconsidered based on the findings of this study.

Summary: The need for an alternative energy source to fossil fuel has led to the search for reliable and sustainable sources that can address environmental challenges and stabilize energy prices. Biofuel, particularly bioethanol, has been identified as a superior alternative, but its high production cost remains a major challenge. Research is focused on finding cheap and sustainable feedstock for bioethanol production, with a current interest in lignocellulosic waste. This review discusses the conversion of lignocellulosic waste to bioethanol, the pretreatment steps involved, and the challenges, prospects, and economic aspects. While biological treatment appears promising, there are still some challenges that can be managed. Developing countries have significant opportunities for biofuel production cost reduction. Enzyme production cost has been identified as a challenge to the economic viability of lignocellulosic bioethanol, but the development of an efficient biocatalyst system for simultaneous saccharification and fermentation (SSF) and consolidated biomass processing may help overcome this challenge. In conclusion, effectively utilizing lignocellulosic waste in an efficient biocatalyst system can provide an economically viable means to overcome the challenges posed by fossil fuel.
