Summary: The aim of this study was to investigate the effects of two bacterial strains on the formation of γ-aminobutyric acid (GABA), flavor, and metabolic pathways in fermented soymilk. The results showed that the A2B1 combination exhibited the highest acid production rate, GABA yield, and flavor content. After fermentation, 55 differential metabolites were produced, with 28 hexanal-dominated metabolites significantly downregulated and 26 alcohol-dominated metabolites significantly upregulated. Significant metabolic pathways included D-alanine, taurine and hypotaurine, and selenocompound metabolism. Furthermore, 2-pentylfuran and 2-butyl2-octenal were identified as contributing to the aroma of fermented soymilk. These findings provide a theoretical basis for future research on GABA-rich fermented foods.

Summary: Textile effluent was treated through sequential electro oxidation (EO) and photo electro oxidation (PEO) using RuO2-IrO2 coated titanium electrode as an anode and cathode, followed by biodegradation. The pre-treatment of textile effluent by photo electro oxidation for 14 h resulted in 92% decolorization. Subsequent biodegradation of the pre-treated textile effluent achieved a 90% reduction in chemical oxygen demand. Metagenomics analysis revealed the involvement of Fla-vobacterium, Dietzia, Curtobacterium, Mesorhizobium, Sphingobium, Streptococcus, Enterococcus, Prevotella, and Stenotrophomonas bacterial communities in the biodegradation of textile effluent. Therefore, the integration of sequential photo electro oxidation and biodegradation offers an efficient and eco-friendly approach for treating textile effluent.
