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 کاملPlasmid-encoded regulator of extracellular proteases in Bacillus anthracis.
Bacillus anthracis Sterne cured of the pXO1 plasmid had enhanced secreted protease activity during the postexponential phase but no change in hemolytic or lecithinase activities. A zymogen profile revealed at least six proteases, including serine, metal, and perhaps cysteine types. There were similar amounts of protease secreted by the closely related species Bacillus cereus and Bacillus thurin...
متن کاملProduction of Extracellular Proteases by Human Pathogenic
Species belonging to the filamentous fungal genus Trichoderma are well known as potential candidates for the biological control of plant pathogenic fungi and as cellulase producers of biotechnological importance. Several data were published in the last decade also about the clinical importance of this genus, indicating that Trichoderma strains may be potential opportunistic pathogens of immunoc...
متن کاملOptimized production of extracellular proteases by Bacillus subtilis from degraded abattoir waste
Article info: Received: 7 September 2015 Accepted: 19 October 2015 ABSTRACT Proteases are ubiquitous in occurrence and are found in all living organisms. These are essential for cell growth and differentiation. The extracellular proteases are of a high commercial value and find multiple applications in various industrial sectors. The present study describes the screening of protease producing b...
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...
