Summary: This study investigates the high gravity fed-batch simultaneous saccharification and fermentation (FB-SSF) of sequentially pretreated sugarcane bagasse (SCB) for enhanced bioethanol production, using the inhibitor tolerant Kluyveromyces marxianus JKH5 C60. The optimized lab-scale FB-SSF, with intermittent feeding of SCB and enzyme, resulted in maximum ethanol titer, efficiency, and productivities of 73.4 g/L, 78%, and 3.0 g/L/h, respectively, after 72 h in the presence of inhibitors. Additionally, fermentation of pentose rich dilute acid hydrolysate of SCB by Pichia stipitis NCIM 3499 yielded an ethanol titer of 6.8 g/L. The overall ethanol yield during the developed process was 260.1 g/kg native SCB, indicating the industrial potential of this bioethanol conversion process.

Summary: Integrated bioprocess strategies can facilitate ethanol production from both C6 and C5 fractions of lignocellulosic feedstocks. A new process concept, SSICF, combines hydrolysis of sugarcane bagasse with xylose isomerization and the co-fermentation of C6 and C5 sugars. Using a multi-enzymatic system with recombinant enzymes immobilized in magnetic nanoparticles, SSICF achieved high ethanol global yields with non-GMO yeast, demonstrating industrial potential.

Summary: In this study, the delignification of sorghum straw biomass was achieved using protic natural deep eutectic solvents (PNADES), followed by saccharification and extractive biobutanol production via ABE fermentation. Among the synthesized PNADES, the eutectic mixture of choline chloride and citric acid showed a significantly higher removal of lignin (90% w/w) and xylan (83% w/w). The cellulose-rich biomass was then subjected to enzymatic hydrolysis and fermentation with Clostridium acetobutylicum to produce biobutanol. Optimization of influential parameters resulted in effective biobutanol productivity, and scale-up of the process in a 2-L bioreactor further improved sugar utilization rate and butanol recovery. Overall, this study demonstrated sustainable operation conditions for large-scale biobutanol production from sorghum straw biomass.

Summary: The study investigated the ability of Limonium angustebracteatum to cope with drought and salt stress. It was found that the plant had high salt tolerance but was sensitive to water deficit. The plant could recover from the first water stress and its salt tolerance was based on the accumulation of Na+, Cl-, and Ca2+ in the roots and leaves.
