additional information | pretreatment of cellulose with ionic liquids such as 1-butyl-3-methylimidazolium chloride, 1-methylimidazolium chloride, and tris-(2-hydroxyethyl)-methylammonium methylsulfate results in more rapid conversion to glucose than hydrolysis with cellulose that is not pretreated | Aspergillus niger | |
tris-(2-hydroxyethyl)-methylammonium methylsulfate | enzymic activity is significantly enhanced in the presence of tris-(2-hydroxyethyl)-methylammonium methylsulfate in buffer. Tris-(2-hydroxyethyl)-methylammonium methylsulfate imparts substantial thermostability to the enzyme | Aspergillus niger |
