Probiotics such as Lactobacillus and Bifidobacterium have been successfully used to promote growth and prevent diseases. Previous reports have demonstrated that Bacillus subtilis (B. subtilis) was a potential probiotic for animals. In this research, 180 B. subtilis were isolated from the soil, identified, and investigated in vitro. Furthermore, five B. subtilis were selected and mixed to invest...

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...

Although several strains of B. subtilis with antifungal activity have been isolated worldwide, to date there are no published reports regarding the isolation of a native B. subtilis strain from strawberry plants in Mexico. A native bacterium (Bacillus subtilis 21) demonstrated in vitro antagonistic activity against different plant pathogenic fungi. Under greenhouse conditions, it was shown that...

members of the genus bacillus are among the most promising candidates for biological control of plant pathogenic bacteria. in this study, cell free supernatants of three strains b. subtilis utb96, b. subtilis utb1 and b. subtilis utb70 against aspergillus flavus r5 were investigated using dual culture assay. strain b. subtilis utb96 showed the highest inhibition effect. thin lyer chromatography...

1. An experiment was conducted to study the effects of different Bacillus subtilis concentrations on productivity, carcase quality, immune response and the gut microflora of broiler chickens. 2. There were 5 treatment groups: control, with no added Bacillus subtilis supplementation; and 4 treatment groups receiving feed supplemented with different concentrations of B. subtilis. 3. Weight ga...

Protoplasts of Bacillus larvae NRRL b-3555 and Bacillus subtilis RM125 (restrictionless, modificationless mutant) were transfected with DNA from the B. larvae bacteriophage PBL1c in the presence of polyethylene glycol. B. subtilis 168 and Bacillus popilliae NRRL B-2309M protoplasts could not be transfected with PBL1c DNA. Protoplasts of B larvae NRRL B-3555 were transformed with plasmids pC194 ...

The Escherichia coli lep gene, encoding signal peptidase I (SPase I) was provided with Bacillus subtilis transcription/translation signals and expressed in this organism. When present on a low-copy-number plasmid, the amount of E. coli SPase I produced (per mg cell protein) in B. subtilis was half that produced in wild-type E. coli cells. The production of E. coli SPase I in B. subtilis was inc...

Translocation, processing and secretion of YvaY, a Bacillus subtilis protein of unknown function, were characterised both in B. subtilis and in Escherichia coli. In its natural host B. subtilis, YvaY was transiently synthesised at the end of the exponential growth phase. It was efficiently secreted into the culture supernatant in spite of a calculated membrane spanning domain in the mature part...
