Among 116 bacterial strains isolated from Korean fermented foods, one strain (SS-76) was selected for producing new oligosaccharides in a basal medium containing maltose as the sole source of carbon. Upon morphological characterization using scanning electron microscopy, the cells of strain SS-76 appeared rod-shaped; subsequent 16S rRNA gene sequence analysis revealed that strain SS-76 was phyl...

In this report, we present a draft sequence of Bacillus subtilis KATMIRA1933. Previous studies demonstrated probiotic properties of this strain partially attributed to production of an antibacterial compound, subtilosin. Comparative analysis of this strain's genome with that of a commercial probiotic strain, B. subtilis Natto, is presented.

introduction: influenza a virus causes unpredictable epidemics and pandemics by creating antigenic variations. with the appearance of each new strain, rapid emergency countermeasures are taken against this new strain. hence, designing an applicable and cross protective strategy to counter this virus is of great importance. to achieve this, choosing conserved antigenic regions in influenza virus...

background and objectives: the essential amino acid l-tryptophan can be produced by a condensation reaction between indole and l-serine, catalyzed by b. subtilis with tryptophan synthase activity. application of the tryptophan is widespread in the biotechnology domain and is sometimes added to feed products as a food fortifier. materials and methods: the optimum concentration of the iranian can...

there is a growing interest in food industry to replace the synthetic chemicals by the natural products with bioactive properties from plant origin. the aim of this study was to determine the chemical composition of mentha pulegium essential oil and to characterize the antimicrobial activities of the essential oil. the essential oil of mentha pulegium was analyzed by gc-ms. the evaluation of th...

Bacterial chemotaxis involves the regulation of motility by a modified two-component signal transduction system. In Escherichia coli, CheZ is the phosphatase of the response regulator CheY but many other bacteria, including Bacillus subtilis, use members of the CheC-FliY-CheX family for this purpose. While Bacillus subtilis has only CheC and FliY, many systems also have CheX. The effect of this...

Two types of white wheat bread (high- and low-type loaves) were investigated for rope spoilage. Thirty of the 56 breads tested developed rope spoilage within 5 days; the high-type loaves were affected by rope spoilage more than the low-type loaves. Sixty-one Bacillus strains were isolated from ropy breads and were characterized on the basis of their phenotypic and genotypic traits. All of the i...

The present study emphasizes the diversity assessment of marine Bacillus species with special reference to biosurfactant production, respective gene expression, and discrimination among Bacillus licheniformis and Bacillus subtilis. Among the 200 individual species of eastern coastal plain of Tamil Nadu screened, five biosurfactant producing potential bacterial species with entirely different mo...

Abstract RNA turnover is essential in all domains of life. The endonuclease RNase Y (rny) one the key components involved metabolism model organism Bacillus subtilis. Essentiality has been a matter discussion, since deletion rny gene possible, but leads to severe phenotypic effects. In this work, we demonstrate that mutant strain rapidly evolves suppressor mutations at least partially alleviate...
