ENZYMATIC HYDROLYSIS OF GLYCOGEN

Enhancing Enzymatic Hydrolysis of Cellulose by Ultrasonic Pretreatment

Slurries of rice-straw cellulose (obtained by delignification and removal of hemicelluloses from the powdered raw material) were subjected to ultrasonic waves at different intensities for various times (constant temperature). Susceptibility of the samples to cellulose-hydrolysis increased initially with pretreatment time, reaching a maximum or a constant level thereafter. Maximum glucose yi...

Effects of Condition Enzymatic Hydrolysis on Degrees of Hydrolysis and Antioxidant Activity of Head Protein of Bighead (Aristichthys nobilis)

Background and Objectives: Enzymatic hydrolysis is an effective practical technology that recovers valuable proteins from far-less farmed fish without losing their nutritional characteristics. Enzymatic hydrolysis of protein sources such as aquatic animals is a type of protein recycling. In the present study, effects of temperature, time and concentration of papain enzyme on hydrolysis degree a...

The enzymatic hydrolysis of glucuronolactone.

Studies over the past 20 years on the metabolism of carbohydrates have implicated glucuronolactone as a precursor of several compounds of physiological interest; namely, L-xylulose (1, 2), ascorbic acid (3, 4), and furan2,5-dicarboxylic acid (5). Studies in viva from two laboratories, demonstrating that mammalian tissues can oxidize glucuronolactone to CO2 (6) but fail to oxidize glucuronic aci...

Enzymatic hydrolysis of cellulosic biomass

technology was selected as a key area for biomass technology development in the 1980s, and the US Department of Energy (DOE) has actively supported the scale up of ethanol production since the Office of Alcohol Fuels was created in the DOE after the ‘energy crisis’ of the 1970s. Although biological conversion of cellulosic biomass to fuels and chemicals through enzymatic hydrolysis of cellulose...
