Forty-five strains, representing 18 species of the genus Bacillus, were surveyed for production of hemolysin against rabbit erythrocytes. Broth cultures of B. cereus, B. alvei, and B. laterosporus contained lysins that closely resembled streptolysin O. B. subtilis and a single strain of B. cereus may produce lysins having characteristics different from those of streptolysin O.

Brevibacillus laterosporus OSY-I1 is a Gram-positive spore-forming bacterium isolated from soil. The bacterium produces brevibacillin, an antimicrobial lipopeptide effective against several drug-resistant Gram-positive bacteria. Here, we present the draft genome sequence of the strain OSY-I1 and the gene cluster responsible for the biosynthesis of brevibacillin.

To isolate and characterize chitinases that can be applied with practical advantages, 57 isolates of chitin-degrading bacteria were isolated from the soil of a suburban wetland. 16S rRNA gene analysis revealed that the majority of these strains belonged to two genera, Paenibacillus and Brevibacillus. Taking thermostability into account, the chitinases (ChiA and ChiC) of a B. laterosporus strain...

The algae, Oscillatoria, is commonly found in prawn ponds and can lead to reduced productivity. We examined metabolites of the bacteria Brevibacillus laterosporus for algicidal qualities. To determine the possible algicidal mechanisms of these bioactive metabolites, different amounts of sterile filtrate of bacterial suspensions were added to cultures containing Oscillatoria. The dry weight, the...

Laboratory cultures of PNG 276, a Bacillus laterosporus isolate obtained from coastal waters off Papua New Guinea, have been shown to produce the novel metabolites basiliskamide A (1), basiliskamide B (2), tupuseleiamide A (3), and tupusleiamide B (4). The structures of 1 to 4 were elucidated by analysis of spectroscopic data and chemical degradation. Basiliskamides A (1) and B (2) show potent ...

Soil contamination by textile and tannery effluents is a great concern to the environment, Complex having number of dyes accumulate in soil there polluting environments loss microbial species soil. Samples were collected physicochemical analyses was determined. The pH basic with 8.0 10.1 from dyeing site respectively. organic carbon very low 0.76% 0.06%, Nitrogen (0.067% 0,095%), phosphorus 0.8...

The success of a microbial pesticide application against house flies developing in manure should accomplish the uniform mixing of active ingredients with this breeding medium, thus enhancing residual effects. The oral administration of the entomopathogenic bacterium Brevibacillus laterosporus to caged poultry species allows the homogeneous incorporation of its active ingredients with fly breedi...
