Previously other groups had reported that Paenibacillus polymyxa NRRL B-30507 produces SRCAM 37, a type IIA bacteriocin with antimicrobial activity against Campylobacter jejuni. Genome sequencing and isolation of antimicrobial compounds from this P. polymyxa strain show that the antimicrobial activity is due to polymyxins and tridecaptin B1. The complete structural assignment, synthesis, and an...

The gene for beta-amylase was isolated from Bacillus polymyxa by molecular cloning in B. subtilis. B. subtilis cells containing this gene express and secrete an amylase which resembles the B. polymyxa beta-amylase and barley beta-amylase in terms of the products it generates during carbohydrate hydrolysis. Starch hydrolysis with this beta-amylase produces maltose, not glucose, whereas maltotrio...

continuous and excessive use of organophosphorus compounds has led to thecontamination of water and soil ecosystems. the degradation of organophosphorusinsecticides, chlorpyrifos, chlorpyrifos- methyl, cyanophos and malathion in mineral saltsmedia were studied. the effect of additional biofertilizers, singly or combined withorganic amendments, on chlorpyrifos and cyanophos degrading activity in...

We investigated the immunostimulatory effects of a novel β-glucan purified from Paenibacillus (P.) polymyxa JB115 on bone marrow-derived dendritic cells (DCs), a type of potent antigen-presenting cells. β-glucan isolated from P. polymyxa JB115 enhanced the viability and induced the maturation of DCs. β-glucan markedly increased the cytokine production of DCs and surface expression of DC markers...

Ketta H., Ryšánek P., Zouhar M. (2012): Detection of Polymyxa graminis in a barley crop in the Czech Republic. Plant Protect. Sci., 48: 65–71. Polymyxa graminis Led. was detected in the roots of barley plants from a field in the Hradec Králové Region (northeastern Bohemia) in May 2008. The fungus was identified as P. graminis on the basis of the morphology of resting spores (cystosori) and spor...

Paenibacillus polymyxa E681, a spore-forming, low-G+C, Gram-positive bacterium isolated from the rhizosphere of winter barley grown in South Korea, has great potential for agricultural applications due to its ability to promote plant growth and suppress plant diseases. Here we present the complete genome sequence of P. polymyxa E681. Its 5.4-Mb genome encodes functions specialized to the plant-...

The prototypical fibroblast growth factor receptor (FGFR) extracellular domain consists of three Ig domains (D1-D3) of which the two membrane-proximal D2 and D3 domains and the interconnecting D2-D3 linker bear the determinants of ligand binding and specificity. In contrast, D1 and the D1-D2 linker are thought to play autoinhibitory roles in FGFR regulation. Here, we report the crystal structur...

The efficiency factor, the number of moles of ATP generated per mole of glucose fermented, was determined in anaerobic, non-carbon-limited N2-fixing cultures of Bacillus polymyxa, Bacillus macerans, Bacillus azotofixans, and Clostridium butyricum through identification and quantitation of the fermentation products by 13C nuclear magnetic resonance spectroscopy and measurement of acetate kinase ...

Paenibacillus polymyxa populations present in the rhizosphere of maize (cultivar BR-201) planted in Cerrado soil were investigated in order to assess their diversity at four stages of plant growth. A total of 67 strains were isolated and all strains were identified as P. polymyxa by classical biochemical tests, API 50CH tests and a set of species-specific primers based on the 23S rDNA sequence....
