Pectinolytic enzymes from actinomycetes for the degumming of ramie bast fibers.
Actinomycetes isolated from 10 different soil and compost samples were screened for production of pectinolytic enzyme activities when grown on pectin-containing solid and liquid media. Pectinolytic enzymes, detected by using plate diffusion tests with a medium containing ramie (Boehmeria nivea) plant material as the sole carbon source, were mainly pectate lyases, but low activities of pectinest...
متن کاملDegumming of ramie fibers by alkalophilic bacteria and their polysaccharide-degrading enzymes.
Three strains of alkalophilic bacteria, Bacillus sp. NT-39, NT-53 and NT-76, were selected for the degumming of ramie fibers and production of polysaccharide-degrading enzymes. After 48 h of incubation with the strains, the loss of the gum might amount to 5.0% or more of the fibers and a number of polysaccharide-degrading enzymes were secreted to the culture supernatants. The residual gum of th...
متن کاملAn Effective Degumming Enzyme from Bacillus sp. Y1 and Synergistic Action of Hydrogen Peroxide and Protease on Enzymatic Degumming of Ramie Fibers
Enzymatic degumming, as an alternative to chemical processing, has attracted wide attention. However, to date, little information about other enzyme components with effective degumming except pectinase has been reported, and there is no report about the effect of bleaching agent (H2O2) on enzymatic degumming and combining enzymatic degumming and H2O2 bleaching process. In this study, we found t...
متن کاملFibrinolytic enzymes from actinomycetes
Fibrinolytic enzymes have nowadays found important place in the medical field. Only few studies had reported the fibrinolytic enzyme production from actinomycetes. So the microbial fibrinolytic enzymes, especially those from actinomycetes, have the potential to be developed as drugs to prevent cardiovascular diseases. Actinomycetes were producing strong enzymes with no side effects, non pathoge...
متن کاملA Chemical Process for Preparing Cellulosic Fibers Hierarchically from Kenaf Bast Fibers
The objective of this research was to evaluate an all-chemical process to prepare nano-scale to macro-scale cellulosic fibers from kenaf bast fibers, for polymer composite reinforcement. The procedure used in this all-chemical process included alkaline retting to obtain single cellulosic retted fiber, bleaching treatment to obtain delignified bleached fiber, and acidic hydrolysis to obtain both...
