to evaluate the effect of intercropping of sorghum and alfalfa on forage yield and on weed biomass production, different proportions of sorghum and alfalfa intercropping system comprised of 50% - 50%, 25% - 75% and 75%-25%, along with sole cultures of sorghum, and of alfalfa were arranged as split plots in time, while a complete plot design with three replications being used to analyze the data...

Production of polyvinly alcohol (PVA) oxidase by Pseudomonas sp. strain VM15C, a PVA degrader of a symbiotic PVA-utilizing mixed culture, was examined in various cultures. Despite the absence of PVA in the culture in nutrient broth, VM15C showed approximately the same productivity of PVA oxidase activity as that in the culture with PVA as the sole carbon source, whereas the productivity in the ...

such petroleum hydrocarbons as ethylene oligomer are among soil and water pollutants. physical and chemical methods employed in elimination of these pollutants, in addition to being inefficient, are damaging to the environment too. throughout the present research, powerful decomposer isolates, namely: lysinibacillus xylanilyticus (a bacterium isolate), and aspergillus niger (a fungal isolate) w...

Mixed intercropping of barley (Hordeum vulgare L.) with faba bean (Vicia faba L.) was compared with sole cropping for three growing seasons 2001–2003) at Holetta Agricultural Research Centre, in the central highlands of Ethiopia. The treatments were sole barley (125 kg ha−1), sole aba bean (200 kg ha−1) and an additive series of 12.5, 25, 37.5, 50 and 62.5% of the sole seed rate of faba bean mi...

Objective: For investigation of intercropping of maize and faba bean, an experiment was conducted in Research Station of Agriculture Faculty of Tabriz University during growing season of 2013. Methods: Experimental design was randomized complete block design with three replications and seven treatment. Treatments included one row intercropping (1:1), 4 strip intercropping pattern with ratios of...

Ethanol is an important industrial product. It can be degraded by microorganisms to use as sole source of carbon. Trichophyton mentagrophytes and Epidermophyton floccosum are most known species of dermatophytes. Their ability to degrade ethanol was detected. Low concentrations of ethanol enhanced two tested species of dermatophytes to grow on culture medium faster in absence of carbon source. A...

A microbial enrichment culture from marine sediment was able to grow on hexadecan-2-one as the sole source of carbon and energy under sulfate-reducing conditions. Oxidation of the ketone involved carboxylation reactions and was coupled to sulfide production. This enrichment culture also grew on 6,10,14-trimethylpentadecan-2-one.
