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...

There are many studies on the effects of probiotics on performance of broiler chickens, but none of them has evaluated the metabolizable energy (ME) equivalency values of probiotics. The aim of this study was to determine the metabolizable energy equivalency value of Bacillus subtilis spore and its potential for decreasing feed ME content and cost. One hundred seventy-six day-old male broilers ...

A Gram-stain-positive, facultatively anaerobic, endospore-forming organism, isolated from the stem of Gossypium hirsutum, was studied to determine its taxonomic position. On the basis of 16S rRNA gene sequence similarity comparisons, strain JM-267T was grouped in the genus Bacillus, related most closely to the type strains of Bacillus simplex and Bacillus huizhouensis (both 97.8%), Bacillus mur...

background: the effect of several probiotics on diseases of the gastrointestinal tract, including gastric ulcers is well reported. however, there are limited numbers of studies assessing the impact of bacillus subtilis (b. subtilis) probiotic on skin wound healing. m aterials and methods: fifty male rats were assigned to 3 different groups randomly. a 1.5 cm longitudinal full thickness incision...

lipases are diversified enzymes in their properties and substrate specificity, which make them attractive tools for various industrial applications. in this study, an alkaline thermostable lipase producing bacteria were isolated from soil of different regions of isfahan province (iran) and its lipase was purified by ammonium sulfate precipitation and ion exchange chromatography. to select a the...
