introduction: diabetes mellitus is an growing national and international public health concern. the number of people affected by diabetes in world by 2030 will be 69% in developing countries. regular physical activity plays a key role in the management of type 2 diabetes melitus, particularly glycemic control. it has been recommended that peoples with type 2 diabetes participate in moderate-int...
aflatoxin is one of the most hazardous mycotoxins injurious to both humans and animals. aflatoxin contamination of crops is a serious economic loss inflicted upon agriculture, food and animal industry throughout the entire world. in nature, there are microorganisms able to alleviate aflatoxin contamination in crop products. in this work, the effects of four strains of bacillus subtilis in reduc...
This study was aimed to evaluate the single and combined effects of sodium diformate as an acidifier and bacilli probiotics (Bacillus subtilis and B. licheniformis) on intestinal histomorphology of juvenile Salmo trutta caspius or 60 days. Hundred juvenile fish weighing 12. 6±1. 4 g were divided into 4 different treatments, including control, 0. 4g B. subtilis+ B. licheniformis /kg diet, 0. 5g ...
The use of Bacillus subtilis as an inoculant can promote plant growth through several mechanisms. Thus, the objective this work was to evaluate efficiency a soybean promoter inoculant. Seven isolates B. (Bs01; Bs02; Bs03; Bs04; Bs05; Bs06 and Bs10) were evaluated for their ability solubilize phosphate synthesis indole acetic acid, in vitro, production biomass plants vegetation House. All able p...
Many different systems of bacterial interactions have been described. However, relatively few studies have explored how interactions between different microorganisms might influence bacterial development. To explore such interspecies interactions, we focused on Bacillus subtilis, which characteristically develops into matrix-producing cannibals before entering sporulation. We investigated wheth...
One of the major issues associated with industrial production of menaquinone-7 (MK-7) is the low fermentation yield. In this study, we investigated the effect of iron oxide nanoparticles coated with 3-aminopropyltriethoxysilane (IONs@APTES) on the production of MK-7 using B. subtilis (ATCC 6633). Decoration of B. subtilis cells with IONs@APTES significantly enhanced both MK-7 production and yie...
As one of the most effective biosurfactants reported to date, lipopeptides exhibit attractive surface and biological activities have great potential serve as biocatalysts. Low yield, high cost production, purification hinder large-scale applications lipopeptides. Utilization waste materials low-cost substrates for growth biosurfactant producers has emerged a feasible solution economical product...
sange siyah dam is located two kilometers down the kabod khani village. the environ of ghorrve city in kurdestan province. this is an clay core dam. in this dam instrumentation is performed in three section and consist of electrical piezometers, total pressure cells, settlement cells and so on. the main objective of instrumentation is to control the behavior of dam body and foundation, end else...
the purpose of this study was to investigate the effect of task repetition on accuracy of iranian efl learners ’speaking ability. in order to achieve this purpose, a null hypothesis was developed: there is no statistically significant difference between accuracy speaking ability in iranian efl learners by use of task repetition. ; of course i should mention that, beside this null hypothesis, an...
Expression of the Bacillus subtilis or Bacillus amyloliquefaciens sacB gene in the presence of sucrose is lethal for a variety of bacteria. Sucrose-induced lethality can be used to select for inactivation of sacB by insertion of heterologous DNA in sensitive bacteria. This procedure has not been applicable to B. subtilis heretofore because expression of wild-type sacB is not detrimental to B. s...
