Lipase 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...
متن کاملPurification of Endoxylanase from Bacillus pumilus B20 for Production of Prebiotic Xylooligosaccharide Syrup; An In vitro Study
Background: The need for more cost-effective compounds is imperative because the demand for prebiotic compounds is ever on the rise. Objective: The focus of this study is the purification of the endoxylanase from Bacillus pumilus B20 and its application in a cost-effective production of the prebiotic xylooligosaccharide (XOS) syrup having a high concentration of oligo...
متن کاملPurification and properties of a xylan-binding endoxylanase from Alkaliphilic bacillus sp. strain K-1.
An alkaliphilic bacterium, Bacillus sp. strain K-1, produces extracellular xylanolytic enzymes such as xylanases, beta-xylosidase, arabinofuranosidase, and acetyl esterase when grown in xylan medium. One of the extracellular xylanases that is stable in an alkaline state was purified to homogeneity by affinity adsorption-desorption on insoluble xylan. The enzyme bound to insoluble xylan but not ...
متن کاملAffinity Purification and Characterization of Recombinant Bacillus sphaericus Phenylalanine Dehydrogenase Produced by pET Expression Vector System
Cloning and expression of the L-phenylalanine dehydrogenase gene, from B. sphaericus in E. coli were done. The gene was cloned in the vector pET16b and transformed into E. coli BL21 (DE3). The functional form of the L-phenylalanine dehydrogenase enzyme was purified by affinity purification techniques, taking advantage of the ability of this enzyme to bind to the nucleotide site affinity dye, Re...
متن کاملToxin 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...
