Degumming of Vegetable Oil by a New Microbial Lipase
Lecitase Ultra lipase is an acidic lipase which exhibits maximal activity at pH=5.0. It takes part in the activity towards both phospholipid and triglyceride structures. When the temperature is over 40 °C, the phospholipase activity predominates, and the lipase activity is partly suppressed. It could be applied for the degumming of vegetable oil, and the phosphatides in the oil were easily conv...
متن کاملNovel process for the simultaneous extraction and degumming of banana fibers under solid-state cultivation
Various process parameters for the production of polygalacturonase by Streptomyces lydicus under solid-state fermentation were optimized. The optimum particle size of wheat bran for polygalacturonase production was in the range of 500-1000 μm. Initial moisture content of 70% was found to be the optimum for enzyme production. The most suitable inoculum size was 1.25 × 10(5) CFU/mL and the optimu...
متن کاملPectinolytic 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...
