Background and Objectives: The purpose of the present study was to investigate effects of various heat shock conditions and fast freezing and subsequent thawing on the viability and recovery of Bacillus coagulans and Bacillus subtilis as probiotic sporeformers, and also to compare spore plate and microscopic counts. Materials and Methods: After preparing the final suspensions of B. coagulans...

conclusions the present study suggests that the enzyme obtained from strain b. subtilis can be used as feed supplement in animal diet also for reduction of phosphorus pollution problem in areas of livestock production. materials and methods the present study was conducted in biotechnology laboratory, motilal nehru national institute of technology, allahabad, uttar pradesh, india. to isolate phy...

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...

Biosurfactant production may be an economic approach to improving oil recovery. To obtain candidates most suitable for oil recovery, 207 strains, mostly belonging to the genus Bacillus, were tested for growth and biosurfactant production in medium with 5% NaCl under aerobic and anaerobic conditions. All strains grew aerobically with 5% NaCl, and 147 strains produced a biosurfactant. Thirty-five...

The in vitro effects of four heat-inactivated bacterial species on the cellular innate immune responses of the gilthead seabream (Sparus aurata L.) were investigated. Head-kidney leucocytes were isolated and incubated for 30 min with two bacteria isolated from seabream skin (Pdp11 and 51M6; members of the Vibrionaceae and in the genus Shewanella) and two bacteria used as probiotics in humans an...
