Bacillus subtilis C3, a commercial textile dye-decolorizing and -degrading bacterium, was isolated from the common effluent treatment plant (CEPT) of the Jetpur textile dyeing and printing industrial sector situated in the district of Rajkot, Gujarat, India. Here, we present the annotated 4.18-Mb draft genome sequence of B. subtilis C3, providing information about the metabolic pathways involve...
جهت کنترل بیولوژیکی بیماری پژمردگی آوندی میخک، ناشی از قارچ fusarium oxysporum f.sp . dianthi، اثر آنتاگونیستی 141 باکتری جدا شده از فراریشه (ریزوسفر) میخک علیه قارچ بیمارگر به روش کشت متقابل مورد بررسی قرار گرفت. از این تعداد، 16 استرین دارای خاصیت آنتاگونیستی بودند که 7 استرین با بیشترین هاله بازدارندگی برای آزمون های بعدی انتخاب شدند. بر اساس آزمون های بیوشیمیایی، فیزیولوژیکی و مرفولوژیکی اس...
مقدمه: بیوسورفکتانت‌ها، مولکول‌های دوگانه دوست منحصر به فردی هستند که کاربرد وسیعی در حذف آلودگی‌های آلی و فلزی محیط‌زیست دارند. هدف از پژوهش حاضر، بررسی و تعیین شرایط بهینه تولید بیوسورفکتانت توسط دو باکتری Bacillus pumilus 1529 و Bacillus subtilis WPI است. مواد و روش ها: در این پژوهش، اثر منبع کربن، دما و زمان گرماگذاری بر تولید بیوسورفکتانت بررسی شد. به‌منظور تشخیص تولید بیوسورفکتان...
Among 45 Bacillus subtilis strains isolated from non-salted types of fermented soybeans produced in several Southeast Asian countries, 20 had the insertion sequence IS4Bsu1 in the chromosome. In contrast, none of 49 B. subtilis strains of non-food origin contained IS4Bsu1. Frequent occurrence of this mobile DNA element in the soybean-fermenting B. subtilis would reflect the fact that few strain...
Bacillus subtilis is a Gram-positive, rod-shaped, spore-forming bacterium. We present the genome sequence of an undomesticated strain, BSP1, isolated from poultry. The sequence of the BSP1 genome supports the view that B. subtilis has a biphasic lifestyle, cycling between the soil and the animal gastrointestinal tract, and it provides molecular-level insight into the adaptation of B. subtilis t...
Supercritical fluid extract of leaves of Vitex negundo was tested for its antimicrobial potential and was compared with that of ethanol extract, ether extract and hydrodistilled oil of leaves. The chemical constituents of extracts were studied by chromatographic techniques. Extracts were evaluated for antimicrobial potential against bacterial strains like Staphylococcus aureus, Bacillus subtili...
Polymerase chain reaction (PCR) for the flagellin central domain coding region (FCD-PCR) was applied to the detection and discrimination of Bacillus subtilis DB9011, a strain with useful functions in agriculture. Cross-reactions were observed in 4 B. subtilis strains with similar flagellin genes (hag). Alignment of partial amino-acid sequences of flagellin and the results of PCR for the 16S/23S...
Bacillus subtilis contains urease structural genes but lacks the accessory genes typically required for GTP-dependent incorporation of nickel. Nevertheless, B. subtilis was shown to possess a functional urease, and the recombinant enzyme conferred low levels of nickel-dependent activity to Escherichia coli. Additional investigations of the system lead to the suggestion that B. subtilis may use ...
