Sugarcane plant engineered to accumulate lipids in its vegetative tissue is being developed as a new bioenergy crop. The crop would be source of juice, oil, and cellulosic sugars. However, limited tolerance industrially recognized yeasts towards inhibitors generated during the processing lignocellulosic biomass produce fermentable sugars major challenge developing scalable processes for second-generation drop-in fuel production. To this end, hydrolysates from sugarcane-'oilcane' bagasse contain added phenolics fatty acids that further restrict growth fermenting microorganisms necessitate nutrient supplementation and/or detoxification hydrolysate which makes fermentation process expensive. Herein, we propose resourceful economical approach growing lab commercial strains S. cerevisiae on unrefined aerobically fermentatively. An equal ratio juice was found optimum by Saccharomyces xylose fermentation. industrial strain grew fermented efficiently under low aeration conditions having an ethanol titer, yield, specific volumetric productivities 46.96 ± 0.19 g/l, 0.51 0.00 g/g, 0.27 0.02 g/g.h 1.95 0.01 g/l.h, respectively, while better higher 24.93 0.09, 0.17 1.04 respectively. Acclimation cultures blended medium significantly improved performance yeast strains. addition transgenic oilcane inedible rich amino acids, averted need expensive steps hydrolysate. provides solution reduce cost at scale
