OBJECTIVE To study the sterilizing effect and mechanism of electrolyzed-oxidizing water (EOW) and electrolyzed-reductive water (ERW) for Bacillus subtilis var. niger (ATCC9372) and Escherichia coli (8099). METHODS The generations of EOW and ERW were made in the ion membrane electrolysis cell. The sterilization manner was the suspension quantitative germicidal test. RESULTS The killing rate ...

I. Cordycepin monophosphate has been shown to inhibit the activity of phosphoribosyl-pyrophosphate amidotransferase (ribosylamine-5-phosphate:pyrophosphate phosphoribosyltransferase (ghitamate-amidating), EC 2.4.2.14) obtained from both pigeon liver and Bacillus subtilis. 2. Evidence is presented for the existence of a phosphorylated derivative of cordycepin in Bacillus subtilis cells which wer...

BACKGROUND Starch, a homopolysaccharide is an important and an abundant food reserve and energy source. Starches are processed to yield different products which find many industrial applications. Alpha-amylases hydrolyze starch by cleaving α-1,4-glucosidic bonds and have been used in food, textile and pharmaceutical industries [Sun et al. 2010]. Enzymatic conversion of starch with amylase prese...

results the pcr approved the bacillus genus of the isolates. the strain of bacillus subtilis was identified using biochemical tests. 40 ºc and ph 11 are the optimum condition for maximum keratinase enzyme activity. objectives the aim of this study was the isolation of feather degrading bacillus spp.from a poultry waste and the optimization of conditions for the highest enzyme activity and feath...

Four phenolics, salviaplebeiaside (1), γ-tocopherol (2), chrysosplenol-D (4), and isovitexin (5), along with α-tocoquinone (3) and β-sitosterol (6) were isolated from the aerial parts of Vitex negundo var. cannabifolia. The isolation was performed using bio-assay tracking experiments. The structures of compounds 1-5 were established by spectroscopic means. The antibacterial activities of the co...
