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 کاملEnzymatic properties of dipeptidyl carboxypeptidase from Bacillus pumilus.
Enzymatic properties of dipeptidyl carboxypeptidase (DCP) from Bacillus pumilus were investigated. The enzyme was more active on tri- and tetrapeptides than angiotensin-converting enzyme (ACE) from rabbit lung. The presence of chloride ion is essential for the hydrolysis. The Km value of angiotensin I for the enzyme was 0.119 x 10(-3) M. The enzyme was not inhibited by the mammalian ACE inhibit...
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...
متن کاملAntitrypanosomal alkaloids from the marine bacterium Bacillus pumilus.
Fractionation of the ethyl acetate extract of the marine bacterium Bacillus pumilus isolated from the black coral Antipathes sp. led to the isolation of five compounds: cyclo-(L-Leu-L-Pro) (1), 3-hydroxyacetylindole (2), N-acetyl-β-oxotryptamine (3), cyclo-(L-Phe-L-Pro) (4), and 3-formylindole (5). The structures of compounds 1-5 were established by spectroscopic analyses, including HRESITOF-MS...
متن کاملPlasmid deoxyribonucleic acid in Bacillus subtilis and Bacillus pumilus.
Two of eighteen strains of Bacillus subtilis examined contained covalently closed circular duplex deoxyribonucleic acid (DNA) of homogeneous size and buoyant density. Strain ATCC 15841 contained about 16 copies per chromosome of plasmid pPL1, a circular DNA element having a molecular weight of about 4.7 times 10(6) and a buoyant density of 1.700. Strain ATCC 7003 contained about one to two copi...
