A strain of Bacillus polymyxa produced a new peptide antibiotic complex, named LI-F, composed of more than ten components. The components, antibiotics LI-F03, F04, F05, F07, and F08 were isolated from the complex by reversed phase HPLC. They are active against fungi, yeasts, and Gram-positive bacteria. The fast atom bombardment mass spectra revealed that the individual isolated antibiotics are ...

A 4.0-kilobase (kb) fragment of Bacillus circulans genomic DNA inserted into pUC19 and encoding endoxylanase activity was subjected to a series of subclonings. A 1.0-kb HindIII-HincII subfragment was found to code for xylanase activity. Maximum expression levels were observed with a subclone that contained an additional 0.3-kb sequence upstream from the coding region. Enhancer sequences in the ...

The development of resistance in bacteria against commonly used antibiotics/drugs is of considerable medical significance. Aim of this study was to determine the microbial load of un-pasteurized packed fruit juices sold in Lahore city and to determine antibacterial activity of five different honey samples against isolated bacteria. Unpasteurized fruit juice samples (n=60) were collected from st...

With the exceptions of Bacillus cereus and Bacillus anthracis, Bacillus species are generally perceived to be inconsequential. However, the relevance of other Bacillus species as food poisoning organisms and etiological agents in nongastrointestinal infections is being increasingly recognized. Eleven Bacillus species isolated from veterinary samples associated with severe nongastrointestinal in...

The present study assessed the effect of seed inoculation with single or multiple plant growth-promoting rhizobacterial (PGPR) strains on yield in spring wheat (Triticum aestivum spp. vulgare var. Kırık) and barley (Hordeum vulgare cv. Tokak) plants in both greenhouse and field conditions during the years 2007 and 2008. The treatments of wheat and barley plants during the first year include...

RNA polymerase has been purified from vegetative cells of Bacillus brevis and resolved into "core" enzyme and sigma factor. The purified enzyme is rapidly inactivated by incubation at low temperatures in the presence of 1-2 mM ATP, dATP, or NAD(+), while other nucleotides at this concentration have little or no effect. Inactivation is not accompanied by the incorporation of an adenylyl or phosp...

The effects of biofertilizers on the growth, yielding, and nutritional status apple trees (in comparison with standard mineral fertilization) was evaluated in 3-years experiment (2018–2020). included following treatments: (i) Super Fos Dar, (ii) Polifoska 6, (iii) Dar + fungi (Aspergillus niger, Purpureocillium lilacinum), (iv) Urea enriched fungi, (v) dose reduced to 60% (vi) bacteria applied ...

background and objective: in the present study, bacillus polymyxa ncim no. 2539 was selected to utilize agro-industrial byproduct (orange peel) for amylase production under submerged fermentation conditions. material and methods: different agro-industrial byproducts like cane molasses, wheat bran, rice bran and orange peel were screened for maximum amylase production. amylase activitiy of bacil...
