Currently, industrial bioethanol production plants employ mainly two types of primary feedstocks such as starch from cereal crops and juice or molasses from sugar crops. About 60% of the global ethanol is produced from sugar crops, while the remaining 40% is produced from starchy grains. Bioethanol from lignocellulosic biomass has recently been studied extensively but still, it is confined to the laboratory or pilot plant. It is easier and cheaper to use free sugar-containing juice as the feedstock of ethanol than starch or lignocellulosic biomass due to the nonrequirement of costly steps such as pretreatment and/or hydrolysis to get fermentable sugars.
Dear Rebiai,
Thank you for asking an interesting question on RG.
microbiological method for the control of methanol in fermented feedstock, is the use of methylotrophic yeast such as Pichia methanolica and Candida boidinii which have the capacity of utilizing pectin or methyl ester moiety of pectin and methanol, thus preventing the accumulation of methanol in fermented products. Finally, instead of an outright ban on traditional fermentation, because of methanol contamination, the mixed alcohol (ethanol and methanol) could be further processed and used as biofuel. Literature abounds on the use of methanol and ethanol as biofuels.
