The present study was concerned with the selection of suitable surfactant for the production of alpha amylase by Bacillus subtilis GCBM-25 in 250 ml shake flask containing 50 ml of fermentation medium. Different surfactants (laundry soap, detergent powder, sulphonic acid, acyle benzene sulphonic acid, liquid soap, Tween 80, sodium silicate, bath soap, sodium tripolyphosphate, sodium lauryl ethe...

The production of extracellular -amylase by producing Bacillus subtilis RSKK96 was studied under solid state fermentation (SSF). Various agroresidues as substrate were studied for enzyme production. The highest enzyme yield was expressed with cotton stalk substrate (1016.3 ± 32.6 U g · 10). Production parameters were optimized as incubation time 72 hours, incubation temperature 37 °C, agitation...

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...

The amino acid sequence of the RNA polymerase (RNAP) α-subunit is well conserved throughout the Eubacteria. Its C-terminal domain (α-CTD) is important for the transcriptional regulation of specific promoters in both Escherichia coli and Bacillus subtilis, through interactions with transcription factors and/or a DNA element called the "UP element". However, there is only limited information rega...
