Characterization of extracellular cellulose-degrading enzymes from Bacillus thuringiensis strains
The gram-positive spore-forming bacteria, Bacillus thuringiensis (Bt) strains produced novel cellulases which could liberate glucose from soluble cellulose, carboxymethyl cellulose (CMC), and insoluble crystalline cellulose. The maximal cellulase activities were obtained after 60 hrs incubation at 28oC in a LB broth medium with 1% CMC. Maximum CMCase activities were got at 40oC and pH 4.0, resp...
متن کاملRelease of extracellular enzymes from Bacillus amyloliquefaciens.
Washed-cell suspensions of Bacillus amyloliquefaciens secrete significant amounts of the extracellular enzymes alpha-amylase and protease for about 15 min in the almost complete absence of protein synthesis. This apparently represents release of preformed enzyme en route to secretion. The release was independent of energy but was affected by temperature. Pulse-labeling experiments showed that n...
متن کاملMolecular characterization of cellulose-degrading Bacillus pumilus from the soil of tea garden, Darjeeling hills, India.
Bio-fuel produced from ethanol is economically and environmentally advantageous in context of changing global climate. A large number of microorganisms are capable of cellulase production but most of them cannot be utilized commercially due to their low activity. In the present study, an effiecient cellulose degrading strain of Bacillus pumilus was obtained after thorough screening for the prod...
متن کاملCharacterization of Cry2-Type Genes of Bacillus Thuringiensis Strains From Soilisolated of Sichuan Basin, China
Sichuan basin, situated in the west of China, is the fourth biggest basin in China. In order to describe a systematic study of the cry2-type genes resources from Bacillus thuringiensis strains of Sichuan basin, a total of 791 Bacillus thuringiensis strains have been screened from 2650 soil samples in different ecological regions. The method of PCR-restriction fragment length polymorphism (PCR-R...
متن کاملPlasmid patterns of Bacillus thuringiensis type strains.
Practically all Bacillus thuringiensis strains contain a set of self-replicating, extrachromosomal DNA molecules or plasmids, which vary in number and size in the different strains. The plasmid patterns obtained from gel electrophoresis have previously been used as a tool to characterize strains, but comparison of the plasmid patterns has been limited in the number and diversity of strains anal...
