Molecular Detection of Lipase A gene in Putative Bacillus subtilis Strains Isolated from Soil
The present study was undertaken to screen the soil samples collected in Iran for the presence of the Bacillus subtilis lipase A gene. The bacterial colonies obtained from the collected soil samples were examined by physical appearance, biochemical tests and the polymerase chain reaction (PCR). Only four colonies were identified as putative B. subtilis strains and all contained the lipase A ge...
متن کاملMolecular Diagnosis and Characterization of Bacillus subtilis Isolated from Burn Wound in Iran
Background: Bacillus subtilis refers to stretched and sometimes curved, gram-positive, aerobic, and catalase-positive bacilli, which has thermo-resistant endospores. It has been known as a normal flora in the human but can be pathogens In the case of opportunistic. Also, it can be the pathogen of nosocomial infections such as wound among hospitalized patients. Purpose of this study was to ident...
متن کاملThe diaminohexose component of a polysaccharide isolated from Bacillus subtilis.
During the study of the acid hydrolysate of a polysaccharide from BtiZZus subtilis (3), the hexosamine fraction (4) was found to give an unidentified spot on paper chromatograms. Its color reactions were typical for an amino sugar, but it moved at a faster rate than glucosamine or galactosamine. Furthermore, degradat,ion with ninhydrin (5) afforded a reducing product possessing a RF higher than...
متن کاملBiological Containment of Genetically Modified Bacillus subtilis.
Genetic manipulation of bacterial spores of the genus Bacillus has shown potential for vaccination and for delivery of drugs or enzymes. Remarkably, proteins displayed on the spore surface retain activity and generally are not degraded. The heat stability of spores coupled with their desiccation resistance makes them suitable for delivery to humans or to animals by the oral route. Despite these...
متن کاملPectinase production and purification from Bacillus subtilis isolated from soil
Pectinases are industrially important enzymes. The aim of this work was the isolation of pectinases producing Bacillus species from soil sample and their identification by phenotypic tests as well as production and purification pectinases enzyme. Isolated bacteria Subjected to various screening activity and gives pectinases screening test positive i.e. bacteria produced pectinases enzyme. The e...
