The enzymatic hydrolysis reaction with supercritical carbon dioxide(SC'-COZ) as a reaction medium to make glucose from starch was investigated. The reaction rate was enhanced at higher temperature and pressure, especially near the critical point of the CO.. The a-amylase and glucoamylase were found
Supercritical carbon dioxide was studied as a solvent for the enzymatic oxidation of cholesterol with molecular oxygen. Enzymes isolated from Strepfomyces sp., Norcardia sp., Pseudornonas sp., and Gloeocysficum chrysocreas are active in supercritical carbon dioxide. For the oxidation of cholesterol
