study of some growth promotion properties of bacterial isolates from animal manures and identification of selected isolatesabstractbackground and objectives: plants growth in agricultural soils are affected by several biological factors. plant growth promoting bacteria can improve growth and yield of agronomic plants through direct and indirect mechanisms. minimizing consequences of using high ...

The present study deals with the effect of increased concentrations of alcohols (methanol and ethanol) on the solubilization of FePO4 and CaHPO4 by Aspergillus niger. The efficiency of solubilization (ES) of inorganic phosphates, fungal growth, acid production and pH variation were determined. The concentrations of alcohols that most favored the solubilization of phosphates were 4% methanol and...

Phosphate solubilizing bacteria (PSB) possessing the ability to solubilize insoluble inorganic phosphates were isolated from rhizosphere soil. Eighty-one potential PSBs thus obtained were quantitatively screened for phosphate solubilization. Of these, four bacteria found to be efficient phosphate solubilizers, were selected for further evaluation, and found that they solubilize tricalcium phosp...

The objective of the current study was to evaluate the effect of a subtilisin protease, without or with inclusion of carbohydrases, on digestibility and retention of energy and protein, as well as the solubilization and disappearance of non-starch polysaccharides (NSP) from corn-soybean meal based diets fed to broiler chickens. Two hundred eighty-eight Ross 308 male broiler chickens were used f...

abstracta pot study was conducted in order to evaluate the effect of plant growth promoting rhizobia (pgpr) on canola growth and ionic composition under salt stress conditions, was conducted as factorial in randomized complete block design with three replications. salinity in four levels of 0, 3, 6 &9 ds/m were evaluated with mixture of salts nacl & mgcl2. canola seeds were inoculated with sele...

Abstract Phosphorus is an essential nutrient required by plants for their growth and development. Phosphates bioavailability in nature approximately 95-99% but insoluble, therefore the plant can not simply use them. The alternative to overcome phosphate deficiency utilizing solubilizing fungi. This research aimed at selecting characterizing fungi rhizosphere of saitomo taro ( Colocasia esculent...

PURPOSE To determine if limited proteolysis of beta-crystallins is associated with insolubilization of proteins in rats lens during maturation and to test if the protease, calpain II, is involved. METHODS Soluble and insoluble lens proteins from 4-day-old to 4-month-old rat lens cortexes and nuclei were separated by two-dimensional electrophoresis. The insoluble proteins from 4-month-old nucl...
