When bacteriophage SP02 infects a Bacillus subtilis culture during or shortly after transformation, the frequency of transformants among the resulting lysogens is greatly reduced relative to that in the uninfected culture. The effect can occur after the deoxyribonucleic acid has been taken up and covalently attached to recipient deoxyribonucleic acid.

Background: A genome-scale metabolic network model (GEM) is a mathematical representation of an organism’s metabolism. Today, GEMs are popular tools for computationally simulating the biotechnological processes and for predicting biochemical properties of (engineered) strains.Objectives: In the present study, we have evaluated the predictive power of two ...

Bacillus subtilis is currently used as an oral probiotic. We examined two commercial B. subtilis probiotic preparations, Enterogermina and Biosubtyl. Surprisingly, physiological and genetic characterization of the bacteria contained in each of these preparations has shown that neither contains B. subtilis.

A hybrid molecule constructed from Escherichia coli plasmid pMB9 and a fragment of Bacillus subtilis 168 deoxyribonucleic acid functions in cells of leu-E. coli, converting them to leucine prototrophy, but fails to survive in strains of B. subtilis 168.

recently, the production of biosurfactants in bioreactors and their use in various pharmaceutical,chemical and food industries have been developed. optimum production is directly related to the physicochemicalcondition of culture medium (such as ph and temperature) and engineering parameters of bioreactors (such asaeration rate, volume of operation and the amount of energy input). understanding...

using environmental-friendly methods in order to remove or reduce oil pollutants and their derivations in the environment are developing. in this study, the biodegrading ability of bacillus subtilis .sp which has been separated from oil-polluted soil was examined. it was revealed that it can reduce surface tension of growth medium and produce bio-surfactant at 37 and 20 degrees centigrade. also...

the aim of this study was to clone the serine alkaline protease-encoding gene from bacillus subtilis 168. this protease, which can have many applications especially in detergent, may be industrially an important enzyme. for the amplification of the gene, pcr was performed with a pair of primers specifically designed for this purpose. electrophoresis of the pcr product showed the expected band o...

N atto is a traditional Japanese food made by boiling or steaming soybeans and fermenting them with the Bacillus subtilis natto. The bacillus bacteria activate a fermenting process that lends the beans their notoriously sour aroma, nutty flavor, and slippery texture. The Bacillus subtilis natto is a rod-shaped bacterium with a relatively high heat tolerance. Compared to other bacteria that have...
