Bacillus pumilus KatX2 confers enhanced hydrogen peroxide resistance to a Bacillus subtilis PkatA::katX2 mutant strain
BACKGROUND Bacillus pumilus cells exhibit a significantly higher resistance to hydrogen peroxide compared to closely related Bacilli like Bacillus subtilis. RESULTS In this study we analyzed features of the catalase KatX2 of B. pumilus as one of the most important parts of the cellular response to hydrogen peroxide. KatX2, the vegetative catalase expressed in B. pumilus, was compared to the v...
متن کاملPlasmid deoxyribonucleic acid in Bacillus subtilis and Bacillus pumilus.
Two of eighteen strains of Bacillus subtilis examined contained covalently closed circular duplex deoxyribonucleic acid (DNA) of homogeneous size and buoyant density. Strain ATCC 15841 contained about 16 copies per chromosome of plasmid pPL1, a circular DNA element having a molecular weight of about 4.7 times 10(6) and a buoyant density of 1.700. Strain ATCC 7003 contained about one to two copi...
متن کاملبررسی توانایی تولید بیوسورفکتانت توسط دو باکتری Bacillus pumilus 1529 و Bacillus subtilis WPI
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...
متن کاملExpression and Secretion of Cyan Fluorescent Protein (CFP) in B. subtilis using the Chitinase Promoter from Bacillus pumilus SG2
Background: Improved cyan fluorescent protein (ICFP) is a monochromic, green fluorescent protein (GFP) derivative produced by Aequorea macrodactyla in a process similar to GFP. This protein has strong absorption spectra at wavelengths 426-446 nm. ICFP can be used in cell, organelle or intracellular protein labeling, investigating the protein-protein interactions as well as assessing the promote...
متن کاملIsolation and characterization of a novel gossypol-degrading bacteria Bacillus subtilis strain Rumen Bacillus Subtilis
OBJECTIVE The aim of the study was to isolate gossypol-degrading bacteria and to assess its potential for gossypol degradation. METHODS Rumen liquid was collected from fistulated cows grazing the experimental pasture. Approximately 1 mL of the rumen liquid was spread onto basal medium plates containing 2 g/L gossypol as the only source of carbon and was then cultured at 39°C to isolate gossyp...
