this study investigated the inhibitory effects of bacillus licheniformis on g1 and g2 aflatoxins in culture media and kilka fish meal. two concentrations of aflatoxins (8 and 12 ppb for g1 and g2) and (2 and 4 ml from aflatoxins standard per 50g of fish meal) were used in culture media and kilka fish meal respectively. the doses of bacillus were 3 and 4% for this experiment. changes of aflatoxi...

AIMS The aim of this study was to investigate the role of proteases in Bacillus spp. of rhizobacteria in suppressing nematode populations and to understand their mechanism of action. METHODS AND RESULTS Rhizobacteria with nematicidal activity were isolated from soil samples of five root knot nematode-infested farms. Among these strains, nematotoxicities of Bacillus strains were intensively an...

leprosy is an infectious and non-fatal disease that mainly involved skin and peripheral nervous system and caused by mycobacterium lepra. this case is a 41-year-old woman with intermittent nasal bleeding and a mass (1.5×2.5 cm) in the right side of lateral nasal wall and a (1×1 cm) mass on septum in the left side of the nose. considering the probability of intranasal tumor, endoscopic biopsy fo...

background one group of significant enzymes produced by bacillus genus are alkaline proteases with several important applications in the daily life as well as common industries such as food, detergents, leather, alcohol and beer production and medical and sanitary industries, beside wastewater treatment, , biotransformation, hydrolyzed proteins and oil manufacturing. objectives in this paper, k...

background petroleum reservoirs have long been known as the hosts of extremophilic microorganisms. some of these microorganisms are known for their potential biotechnological applications, particularly production of extra and intracellular polymers and enzymes. objectives here, 14 petroleum liquid samples from southern iranian oil reservoirs were screened for presence of biosurfactant‐producing...

background: bacillus anthracis may usually cause three forms of anthrax: inhalation, gastrointestinal and cutaneous. the gastrointestinal (gi) anthrax develops after eating contaminated meat. thus, in this paper were report 5 cases of intestinal anthrax. case presentation: we report a case series of intestinal anthrax, with history of consumption of raw or poorly cooked liver of sheep. one pati...

conclusions in this study, we isolated b. licheniformis producing an organic solvent-stable protease from oil-contaminated soil. the protease was stable and active in various organic solvents. by purification, the protease could be used as a biocatalyst for organic solvent-based enzymatic synthesis. results according to 16srdna sequencing, strain isa9 was identified as a new strain of bacillus ...

Immunotherapy with Bacillus Calmette-Guérin is widely used for treatment and prophylaxis of superficial urothelial cancer. Complications associated with Bacillus Calmette-Guérin treatment are common. The authors describe a case of granulomatous inflammation of the penis associated with intravesical Bacillus Calmette-Guérin therapy, presenting with multiple erythematous and painless nodules loca...
