a field experiment was conducted during 2009-2011 at the aligarh muslim university agricultural research farm, india, to evaluate the efficacious nature of some oil-seed cakes such as neem cake and castor cake, a botanical calotropis procera and phosphate solubilizing bacteria (psb) pseudomonas fluorescens singly and in various combinations, on the growth and productivity of trigonella plant. g...

Phosphorus is a major essential macronutrient for plant growth, and most of the phosphorus in soil remains in insoluble form. Highly efficient phosphate-solubilizing bacteria can be used to increase phosphorus in the plant rhizosphere. In this study, 13 isolates were obtained from waste mushroom residues, which were composed of cotton seed hulls, corn cob, biogas residues, and wood flour. NBRIP...

This paper reports a study of the effect of three nuclear and one thermal power plants on the microbial ecology of soils. Populations of bacteria, actinomycetes, fungi, cellulolytic microbes, phosphate-solubilizing microbes and nitrogen-fixing microbes in the soil in the vicinity of each plant were studied. Soils were acidic at three sites, and moisture contents of the power plant soils were lo...

The enzyme quinoprotein glucose dehydrogenase (GDH) catalyses the oxidation of glucose to gluconic acid by direct oxidation in the periplasmic space of several Gram-negative bacteria. Acidification of the external environment with the release of gluconic acid contributes to the solubilization of the inorganic phosphate by biofertilizer strains of the phosphate-solubilizing bacteria. Glucose deh...

Sustainable phosphorus (P) use to meet the global food demand is a major challenge for agriculture. A number of soil microorganisms may influence plants’ ability utilize different chemical forms in rhizosphere. Inoculating phosphate-solubilizing together with rock phosphates (RP) has intrigued researchers over century. However, microbe-mediated mobilization mechanisms RP remain seldomly compreh...

Using the isotope dilution P technique, a study was conducted to evaluate the P uptake and growth improvement of aerobic rice genotype (M9) inoculated with phosphate-solubilizing bacteria (PSB16, Bacillus sp.) and applied with Christmas Island Phosphate Rock (CIPR), and oxalic acid (OA). An absence of PSB and OA was considered as control treatment. The inoculation of PSB16 strain and OA applica...
