Toxin production by Bacillus pumilus.
Two strains of Bacillus pumilus (M11 and M38) and one strain each of Bacillus cereus (M27), Bacillus subtilis (M67), and Enterobacter agglomerans (M14) were identified from the air of Lancashire cotton mills. These strains were tested for cytopathic effects in Vero cells; B pumilus and B cereus strains were also examined for haemolytic activity, lecithinase production, and proteolytic action on...
متن کاملOptimization of Chitinase Production by Bacillus pumilus Using Plackett-Burman Design and Response Surface Methodology
A soil bacterium capable of degrading chitin on chitin agar plates was isolated and identified as Bacillus pumilus isolate U5 on the basis of 16S rDNA sequence analysis. In order to optimize culture conditions for chitinase production by this bacterium, a two step approach was employed. First, the effects of several medium components were studied using the Plackett-Burman design. Among various ...

متن کاملOptimization of the Cellulase Free Xylanase Production by Immobilized Bacillus Pumilus
Background: The extracellular xylanase secreted by microorganisms is a hydrolytic enzyme, which arbitrarily cleaves the β-1, 4 backbone of the polysaccharide xylan; an enzyme used in the food processing, bio-pulping and bio-bleaching. The commercial production of the xylanase is limited because of a higher cost involvement, which can be overcome by the cost-effective production...
متن کاملLipase from Bacillus pumilus RK31: Production, Purification and Some Properties
A new lipolytic strain of Bacillus sp. was isolated from oil contaminated soil sample. On measurement of biochemical parameters and 16S rDNA sequence information the strain was identified as Bacillus pumilus RK31 (NCBI accession no GQ463238). The lipase purification steps involved, 60% ammonium sulphate saturation, gel filtration chromatography using Sephadex G200 and ion exchange chromatograph...
