Effect of Yeast Extract on Bioethanol Production from Banana Hydrolysate
Bioethanol is one of the most frequently used biofuels. It is produced by fermenting sugars derived from lignocellulosic biomass and hydrolysing cellulose from that biomass. Yeast extract, a by-product of yeast cells, is widely utilised in bacterial growth mediums as a nutritional resource. However,...
