Abstract:In order to maximize the glucose yield in the subsequent enzymatic hydrolysis, corn stalk was pretreated with sulfite to overcome the recalcitrance of lignocellulose (SPORL) under different operational conditions (pretreatment temperature, bisulfite charge, and pH). The parameters optimized included from 0 to 7% (w/w) on od dry (od) substrate, pretreatment temperature 160 to 190 oC, and pH 2.2 to 6.7 required in the process. The results indicated that after the SPORL pretreatment of corn stalk with 7% bisulfit… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
