Hydrodynamic cavitation mediated Spirulina valorisation with insights into phycocyanin extraction and biogas production.

Commercial phycocyanin extraction is energy-intensive and lacks scalability. Alternatively, this study reports the systematic investigation of hydrodynamic cavitation for intensified phycocyanin extraction from Spirulina. Additionally, biomethane potential of the residual biomass, obtained after phycocyanin extraction was also investigated.

Comparative evaluation of biological, physical, and chemical approaches for the mitigation of sterigmatocystin: Mycotoxin of growing concern.

Sterigmatocystin is a carcinogenic and genotoxic mycotoxin that remains a significant health risk to human and animal populations. The present study examined three different methods (biological, physical, and chemical) for STC removal. The nanolignin indicated 81.

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.
