Bacillus subtilis spore coat.
In response to starvation, bacilli and clostridia undergo a specialized program of development that results in the production of a highly resistant dormant cell type known as the spore. A proteinacious shell, called the coat, encases the spore and plays a major role in spore survival. The coat is composed of over 25 polypeptide species, organized into several morphologically distinct layers. Th...
متن کاملProperties of the Bacillus subtilis spore coat.
About 70% of the protein in isolated Bacillus subtilis spore coats was solubilized by treatment with a combination of reducing and denaturing agents at alkaline pH. The residue, consisting primarily of protein, was insoluble in a variety of reagents. The soluble proteins were resolved into at least seven bands by sodium dodecyl sulfate gel electrophoresis. About one-half of the total was four p...
متن کاملLocalization of Spore Markers on the Chromosome of Bacillus Subtilis.
Takahashi, I. (McMaster University, Hamilton, Ontario, Canada). Localization of spore markers on the chromosome of Bacillus subtilis. J. Bacteriol. 89:1065-1067. 1965.-Attempts were made to locate spore markers on the chromosome by determining the mapping distance of ery(r), str(r), phe, tyr, and ser markers to which the spore markers are closely linked. The results obtained indicated that locu...
متن کاملComparative characterization of silver nanoparticles synthesized by spore extract of Bacillus subtilis and Geobacillus stearothermophilus
Objective(s): Silver nanostructures have gathered remarkable attention due to their applications in diversefields. Researchers have recently demonstrated that bacterial spores are capable of reducing silver ions toelemental silver leading to formation of nanoparticles.Materials and Methods: In this study, spores of Bacillus subtilis and Geobacillus stearothermophilus wereemployed to produce sil...
متن کاملEffect of a small, acid-soluble spore protein from Clostridium perfringens on the resistance properties of Bacillus subtilis spores.
Alpha/beta-type small, acid-soluble spore proteins (SASP) are essential for the resistance of DNA in spores of Bacillus species to damage. An alpha/beta-type SASP, Ssp2, from Clostridium perfringens was expressed at significant levels in B. subtilis spores lacking one or both major alpha/beta-type SASP (alpha- and alpha- beta- strains, respectively). Ssp2 restored some of the resistance of alph...
