an investigation was conducted to study the larvicidal activity of teknar (san-402-i-bacillus thuringiensis, serotype h-14, sandoz, 600 itu/mg) on mosquitolarvaein kazeroun, fars province, southern iran. five experimental plots were selected randomly in a rice field and three concentrations of teknar: .0003, .0006 and .0012 cc/1 was used. maximum larval mortality usually occurred during the fir...

background and objectives: research on xylanase has markedly increased due to its potential applications in pulping and bleaching processes using cellulose free preparations, textile processes, the enzymatic saccharification of lignocellulosic materials and waste treatment. the present study was aimed at isolation and characterization of xylan degrading strain of bacillus cereus from soil for p...

Bacillus Sp. was isolated near the mining area and was studied for biosorption U and Th. This study presents uptake of uranium (U) and thorium (Th) by live and dead cells of Bacillus Sp. Increasing concentration of U and Th showed decrease in absorption by Bacillus Sp. Dead cells of Bacillus Sp. exhibited same or more uptake of U and Th than living cells. Increasing temperature promotes uptake ...

Aiming to develop a DNA marker specific for Bacillus anthracis and able to discriminate this species from Bacillus cereus, Bacillus thuringiensis, and Bacillus mycoides, we applied the randomly amplified polymorphic DNA (RAPD) fingerprinting technique to a collection of 101 strains of the genus Bacillus, including 61 strains of the B. cereus group. An 838-bp RAPD marker (SG-850) specific for B....

Microbial culturomics, which investigates microbial diversity by combining diversified culture conditions, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry and 16S rDNA identification, allowed to identify five new species within the Bacillus genus. Bacillus massiliglaciei strain Marseille-P2600T, Bacillus mediterraneensis strain Marseille-P2384T, Bacillus massilinige...

A bronchopneumonia of calves in the early months of life is described and its etiology associated definitely with a minute bacillus, Bacillus actinoides. Bacillus pyogenes, Bacillus bovisepticus, and, less frequently, staphylococci and streptococci may appear later in the affected lungs. Subcutaneous injections of cultures of Bacillus actinoides produce large indurations ending in necrosis. Sim...

The complete sequencing and annotation of the genomes of industrially-important Bacillus species has enhanced our understanding of their properties, and allowed advances in genetic manipulations in other Bacillus species. Post-genomic studies require simple and highly efficient tools to enable genetic manipulation. Here, we summarize the recent progress in genetic engineering strategies for Bac...

Bacillus spp. are Gram-positive spore-forming bacteria used commercially as probiotics in the larviculture of fish. Bacillus spp. can act positively on cultured organisms by enhancing their survival and growth, stimulating their digestive and immune systems, and improving water quality. In this present study, grass carp larvae were fed on Artemia urmiana, Artemia fransiscana and Artemia parthen...
