Attempting to correlate the characteristics of fractionated components from bamboo its susceptibility enzyme is often inconclusive depending on parameters pretreatment conditions. Based integrated analysis chemical components, cellulose bioconversion, characteristic property isolated hemicellulose, and lignin, optimal mild operation for Moso was 4% NaOH in 20% ethanol aqueous solution. A total ...

A single topical application of 1.0 mg of crotol oil or 17 nmoles of 12-O-tetradecanoyl-phorbol-13-acetate (TPA) resulted in a rapid, transient stimulation of mouse epidermal ornithine decarboxylase activity. The activity reached a peak (230-fold greater than control after TPA) at 4 to 5 hr after croton oil or TPA treatment and returned to control level by 12 hr. The stimulation of S-adenosyl-L...

The effect of pretreatment of rats with 5-fluorouracil (5-FU) on hepatic drug-metabolizing enzyme activities was examined. Male rats, weighing 165g, were given a single i.p. injection of 5-FU, 120 mg/kg, and 7 days later the drug-metabolizing enzyme activities of a 10,000 x g supernatant fraction from liver homogenates were exam ined. Aniline hydroxylase, ethylmorphine /V-demethylase, and 2-(me...

BACKGROUND Lignin is embedded in the plant cell wall matrix, and impedes the enzymatic saccharification of lignocellulosic feedstocks. To investigate whether enzymatic digestibility of cell wall materials can be improved by altering the relative abundance of the two major lignin monomers, guaiacyl (G) and syringyl (S) subunits, we compared the degradability of cell wall material from wild-type ...

Lignocellulose nanofibrils (LCNFs) were prepared using a two-step deep eutectic solvent (DES) and enzymatic pretreatment followed by mechanical defibrillation, we examined the effects of conditions on different characteristics LCNFs thus obtained. The yielded DES (Enz-LCNF) exhibited well-defibrillated entangled web-like structure with an average fiber diameter ranging from 15.7 to 20.4 nm. Fur...
