On sporulation the slender vegetative rods swell and form larger spindle-shaped cells in which the spores are formed. When the spores mature they lie in a lateral position cradled in canoe-shaped parasporal bodies which are highly basophilic and can be differentiated from the surrounding vegetative cell cytoplasm with dilute basic dyes. On completion of sporulation the vegetative cell protoplas...

A bacterial formulation containing spores of a Brevibacillus laterosporus strain from Sardinia, known to be toxic by ingestion to the house fly (Musca domestica), was assayed in laboratory, outdoor, and field conditions for the control of immature stages of this pest. In all laboratory assays, the bacterial formulation exhibited toxicity against house fly larvae. A concentration of 1 x 10(8) sp...

Seventy-two bacterial strains were isolated from twenty various sources including soil, water, rotten fruits, vegetables etc. Preliminary screening for pectinase producing bacterial strains was done by well plate method and twenty-six bacterial strains gave zones on Minimum Salt (MS) medium supplemented with 0.2% pectin. Most of the isolates belonged to plant origin, either rotten fruits or veg...

Objectives: In the present study, it was reported effects of some nutritional (amino acid, carbon, nitrogen and metal sources) physical factors (pH temperature) on antibacterial substance activity Brevibacillus laterosporus EA62. Methods: The agar well diffusion assay performed to evaluate substance. new examined against four pathogenic bacteria under different conditions. Results: best obtaine...

a 4 days study was conducted to determine the effects of different concentration of bioaugmentor bacterial strain bacillus licheniformisi, b. subtilis, b. polymyxa, b. laterosporus and b. circulans (protexin aquatech, uk) on adjustment of parameters of water quality as tan, no2-n, no3-n and turbidity from the effluent of common carp ponds. effects of time and concentration were studied as a com...
