Effects of advanced oxidation process on biological treatment of spent fermentation broth.

The present study aimed to establish the feasibility of the wastewater treatment process generated from an oleaginous fermentation plant. Treatment of spent fermentation broth (SFB) poses significant environmental challenges due to its high organic load, recalcitrant compounds, and potential toxicity. The synergistic effects of combining ozone-based advanced oxidation process (O-AOP) with biological treatment for the efficient degradation of pollutants in spent fermentation broth.

Green Downstream Processing Method for Xylooligosaccharide Purification and Assessment of Its Prebiotic Properties.

Xylooligosaccharides (XOS) obtained from lignocellulosic biomass after autohydrolysis primarily consist of lignin-derived impurities and autogenerated inhibitors like furfural, hydroxymethylfurfural, and acetic acid. In this study, graphene oxide-mediated purification (GOMP), a novel and environmentally friendly downstream processing method, was developed for the purification of XOS from hydrolysate obtained after ozone-assisted autohydrolysis of wheat bran. GOMP resulted in appreciable recovery of total XOS from the hydrolysate (73.

Food-grade xylitol production from corncob biomass with acute oral toxicity studies.

Xylitol, a sugar substitute, is widely used in various food formulations and finds a steady global market. In this study, xylitol crystals were produced from corncob by fermentation (as an alternative to the chemical catalytic process) by a GRAS yeast Pichia caribbica MTCC 5703 and characterized in detail for their purity and presence of any possible contaminant that may adversely affect mammalian cell growth and proliferation. The acute and chronic oral toxicity trials demonstrated no gross pathological changes with average weekly weight gain in female Wistar rats at high xylitol loading (LD > 10,000 mg/kg body weight).

Water footprint and wastewater quality assessment of yeast single cell oil production: Gate to gate approach for industrial water sustainability.

Effective water resource utilization and sustainability for industrial operations is a growing concern. With increased industrial water demand, abstraction and water quality changes are rising. In India, distilleries generate more than 40.
