Advances in the ethanol fermentation process are essential to improving performance of bioethanol production. Fed-batch is a promising approach increase final titer, which benefits recovery industry's downstream process. However, development feeding strategies, crucial control variable fed-batch approach, limited. Thus, present work, different modes substrate delivery—fixed feeding, adapted feeding—were investigated cultures Saccharomyces cerevisiae 5-L bioreactor. Evolved gas production, was positively correlated with glucose consumption, used adjust sugar feed rate fermentations under an strategy. The strategy enhanced productivity by 21% compared fixed strategy, stable, and titer reached 91 g/L (~ 11.5%, v/v) at end fermentation. Moreover, cell biomass accumulation growth were significantly improved when using effect nitrogen availability on further explored low-nitrogen content medium. results showed that, even low conditions (N/C = 0.046:10), maintained same as nitrogen-rich medium feeding. Overall, these suggest that delivery could help reduce costs improve current facilities industry.Future work will integrate strategies other approaches • Novel continuous developed for 21%. concentration (11.5%, no residual sugar.

The growing advocacy for greener climates, coupled with increasing global energy demand driven by urbanization and population growth, highlights the need sustainable solutions. Repurposing food wastes as substrates offers a promising approach to enhancing cleaner generation promoting circular economy. This study investigated potential of spent coffee grounds (SC) biosolids cake (BS) from tea producing valuable fuels chemicals through acetone–ethanol–butanol (ABE) fermentation. Clostridium beijerinckii NCIMB 8052 was used ferment 100% 50% hydrolysates derived Parr-treated enzyme-hydrolyzed (PEH, PEH50), non-hydrolyzed (PNEH, PNEH50), non-Parr-treated hydrolyzed (NPEH) SC wastes, well (BSH, BSH50) BS (NBH, NBH50). Fermentation unmodified C. poor. Following CaCO3 modification hydrolysates, ABE titer, yield, productivity increased, highest values obtained PEH50 NBH. Specifically, led increased butanol in PEH50, while NBH exhibited higher yield than non-CaCO3-modified hydrolysates. Additionally, H2 gas production 1.41- 1.13-fold higher, respectively, other These findings suggest that can be valorized hydrogen and, thereby, contribute management, sustainability, cost-effective biofuel production.
