Integral process assessment of sugarcane agricultural crop residues conversion to ethanol

Effects of Enzyme Volumes on Hydrolysis and Fermentation for Ethanol Production From Leftover Cooked Rice

“…However, it was found that the ethanol production became lower when the RS concentration further increased. This is probably because the RS concentration is too high to inhibit the activity of yeast for ethanol production ( Manfredi et al, 2018 ). In the batch V3, the RS further decreased from 30 h, while the COD and ethanol were no longer increased.…”

Biomass Waste as Sustainable Raw Material for Energy and Fuels

“…SSF was further optimized by incorporating a short pre-saccharification followed by simultaneous saccharification fermentation (pSSF). This alternative provides benefits by supporting high loads of solids, reducing quickly the initial viscosity of the substrate that leads to an increase of ethanol yield [32]. Specifically, the substrate is incubated with hydrolytic enzymes in a short time, generally between 8 and 24 h. Then, the SSF proceeds when the microorganism is inoculated, improving the saccharification process due to the different optimum temperatures of the enzymes (50 • C) and the traditional fermentation yeasts (30 • C) [33,34].…”

Cellulose-deconstruction potential of nano-biocatalytic systems: A strategic drive from designing to sustainable applications of immobilized cellulases

“…The biomass conversion into ethanol was more conveniently obtained from Penicillium cellulase [140]. In solid waste management, cellulase enzyme is being used to convert the agricultural solid wastes into beneficial products [141,142]. The wastes lignocellulosic materials are also reported to produce renewable energy sources such as bio-methane and bio-hydrogen [143].…”
