Comparative assessment of acids and alkali based pretreatment on sawdust for enhanced saccharification with thermophilic cellulases

“…Effect of cellulases loading on the saccharification of saw dust. Therefore, it is suggested to use an optimized cocktail of cellulases for obtaining a better saccharification yield by setting aside feedback inhibition constraints (Haq et al, 2020). Enzyme activity can also be inhibited by the production of sugars during enzymatic action so, constant removal of sugars produced can be efficient to increase saccharification yield (Xiao et al, 2004).…”

“…Softwood is more resilient type of wood for bioethanol production as compared to agricultural crops waste and is composed of three biopolymers namely cellulose, hemicellulose and lignin (Bibi et al, 2017). Several bacteria and other microorganisms are capable to reap energy from different cellulosic substrates as they possess highly specific and proficient enzymes but high polymerization and crystallinity of the substrate is the main hindrance in their catalytic activity (Haq et al, 2020;Yu et al, 2016). Therefore, it is necessary to carry out pretreatment which targets the inter fibril and intra fibril structure of the substrate exposing the cellulose and hemicellulose for further processing (Hsu, 2018).…”

Intensification of 2-phenylethanol production using an aerated system assisted by a membrane-based solvent extraction technique

“…Nevertheless, the development of bioprocesses to produce 2-PE is limited by its inhibitory nature during the bioconversion. Additionally, the production of ethanol as a by-product during the bioconversion has influenced the yeast growth, affecting viability during industrial processes, and contributing to the reduction of the production of 2-PE (Shu et al, 2020;Haq et al, 2020). The critical concentration of 2-PE affecting cell viability has not been defined yet.…”
