A CONSIDERABLE number of cases of panophthalmitis attributed to the Bacillus subtilis have now been recorded (Poplawska, 1891; R6mer, 1901; Frangois, 1934; Greenspon, 1918; Motolese, 1936; Reese and Khorazo, 1943). In these cases the organism had an exogenous origin and entered the eye through a perforating wound or post-operatively. Davenport and Smith (1952) suggest that many cases of panopht...

Bacillus subtilis strain B7-S screened from18 strains is an aerobic, endospore-forming, model organism of Gram-positive bacteria which is capable to form vanillin during ferulic acid bioconversion. The bioconversion of ferulic acid to vanillin by Bacillus subtilis B7-S (B. subtilis B7-S) was investigated. Based on our results, the optimum bioconversion conditions for the production of vanillin ...

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...

bacillus subtilis k40b was isolated from rice rhizospheres and its potential for production of xylanase was evaluated using biochemical methods. the gene for xylanase in b. subtilis k40b was amplified, sequenced and assigned to the ncbi genebank. the gene size was estimated to be 563 bp encoding 413 amino acids. comparison of the xylanase gene with reference sequences showed that the xylanase o...

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...

There is a growing appreciation for the impact that bacteria have on higher organisms. Plant roots often harbor beneficial microbes, such as the Gram-positive rhizobacterium Bacillus subtilis, that influence their growth and susceptibility to disease. The ability to form surface-attached microbial communities called biofilms is crucial for the ability of B. subtilis to adhere to and protect pla...

a new system is presented for the generation ofrecombinant bacillus subtilis strains without antibioticmarkers. this system is based on two plasmids constructed in escherichia coli. the first plasmid phm30contains an incomplete hisi gene, the last gene in thehistidine biosynthesis operon of b. subtilis and part ofthe genes yvca and yvcb of unkown function flankinghisi at the 3´-end. the spectin...
