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...

endo-beta-(1,3)-(1,4)-glucanase. encoding a xylanase and an expression, and sequence analysis of genes Bacillus polymyxa: molecular cloning, Two beta-glycanase genes are clustered in

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 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....

Forty yeast strains isolated from soils taken from different locations in Egypt were tested for their P-solubilizing activities on the basis of analyzing the clear zone around colonies growing on a tricalcium phosphate medium after incubation for 5 days at 25degreesC, denoted as the solubilization index (SI). Nine isolates that exhibited P-solubilization potential with an SI ranging from 1.19 t...

Effluents from monosodium glutamate manufacturing plants possess a high strength of COD (10,000--30,000 mg/l), ammonium (15,000--25,000 mg/l), sulphate (15,000--30,000 mg/l) and very low pH (< 2) (Yang et al., 2005). Effluents from sweat potato starch industry contains a high load of protein, pectin, and starchy materials with the COD of 10,000 35,000 mg/l (Mishra et al., 2004). Due to the low ...
