Summary: This study evaluated the impact of initial conditions and pitching methods on the mixed fermentation process and the characteristics of the final product. The results showed that the ethanol and lactic acid concentration of the final product were highly dependent on the initial conditions and pitching order. Interestingly, the presence of lactic acid bacteria did not significantly affect the final ethanol concentration. Optimization of conditions could improve the sour beer production process.

Summary: The study investigated the mechanism of GABA production using a co-culture of GABA-producing Lb. brevis 145 and Streptococcus thermophilus 1275. The co-culture showed enhanced sugar utilization, lactic acid production, improved GABA production, and a decrease in MSG level during fermentation. Correlation between GABA production and sugar utilization was weak, with the acidic environment created by lactic acid playing a crucial role in influencing GABA synthesis.

Summary: Oxidative stress (OS), induced by reactive oxygen species (ROS), is a phenomenon that can lead to various neurological and physiological diseases. This study investigated the protective effects of Lactobacillus brevis MG000874 against oxidative injuries induced by D-galactose in mice. It was found that L. brevis MG000874 improved the antioxidant status and recovered the antioxidant activities of SOD and CAT enzymes in the stress mice. Furthermore, L. brevis MG000874 altered the gene expression of OS markers and mitigated damage to the kidney and liver effectively in D-gal-induced mice.

Summary: Xylanase releases xylo-oligosaccharides that stimulate the growth of lactobacilli in the gut. The study found that certain cell-surface WxL and S-layer proteins in Lactobacillus brevis play a role in assisting the cellular adhesion of the bacteria to plant cell wall polysaccharides. These proteins were also found to have cellulose- and xylan-binding ability.

Summary: In this article, the potential mitigation of imidacloprid toxicity on Danio rerio by Lactobacillus brevis 47f was examined. It was found that even sublethal concentration of imidacloprid could lead to fish death, but the use of Lactobacillus brevis 47f partially reduced the toxic effects. The kidneys were the most affected organs, and the combined action influenced the pro/anti-inflammatory cytokines.

Summary: In this study, five strains of lactic acid bacteria were identified for their ability to remove zearalenone (ZEN) from food and feed. These bacteria not only reduced the toxicity of ZEN, but also bonded with it through interactions with cell wall compounds. The findings suggest that these strains have the potential to be used as detoxification agents for ZEN removal.

Summary: This study assessed the potential of using lactic acid bacteria for depleting non-GOS sugars from a crude GOS mixture, aiming to combine the prebiotic characteristics of purified GOS with the health-promoting effects of lactic acid fermentation metabolites. Supplementation of crude GOS with casein hydrolysate and retardation of acidification during fermentation stimulated cell growth, mono- and disaccharide consumption, overall organic acid production and diversity of the produced acids. Fermentation by specific strains resulted in the production of high purity GOS media.

Summary: A novel one-pot, three-component reaction conducted under electrochemical conditions was studied. The reaction involved 2-aminothiophenols, aldehydes, and malononitrile, using TBABF4 as an electrolyte and CuI as a catalyst. The proposed reaction mechanism suggested that CuI served as an electron relay. This method offers simplified operation, high atom economy, and mild reaction conditions.

Summary: Sulfide compounds show promise as electrocatalysts for water splitting, but their performance is limited by factors such as limited active sites and hindered substance transport. This study successfully prepared a high-entropy sulfide (ZnCoMnFeAlMg)(9)S-8, which reduced grain size and increased specific surface area, enabling the realization of a dual-functional catalyst with multiple catalytic sites. High entropy also modulated the electronic properties of sulfides, reducing the potential energy barrier for hydrolysis. This research introduces a new approach for functionalizing high entropy nanomaterials and improves the performance of water splitting catalysts.
