The objective of this study was to evaluate possible effects mineral fertilizer (NPK), one commercial and three N2-fixing, P-solubilizing and/or ACC deaminase-containing bacteria based bio-fertilizers in triple strains combinations (BF9: Bacillus megaterium 47/9+ Paenibacillus macquariensis RC696 + Pseudomonas fluorescens 9/7; BF10: RC665+ RC382 BF11: simplex RC64 putida 3/10 Burkholderia pyrro...

dissolution of phosphate by p solubilizing microorganisms is dependent on the environmental conditions and the composition of the medium culture. present study conducted to investigate the effect of two fungal species, moisture content and rock phosphate content on water soluble phosphate (wsp), ph and changes of medium weight with time. two fungi aspergillus niger and one isolate from rock pho...

A field experiment was conducted during rainy seasons of 2007-2009 in India (Manipur) to study the effect of different sources and levels of phosphorus on productivity of soybean [Glycine max (L.) Merrill]. The treatments consisted of four sources of phosphorus [Single super phosphate (SSP), Di-ammonium phosphate (DAP), Single super phosphate (SSP)+Phosphate solubilizing bacteria (PSB), Di-ammo...

Phosphorus is one of the key factors that regulate soil fertility. Its deficiencies in soil are largely replenished by chemical fertilizers. The present study was aimed to isolate efficient phosphate solubilizing fungal strains from Eisenia fetida vermicompost. Out of total 30 fungal strains the most efficient phosphate solubilizing one was Emericella (Aspergillus) nidulans V1 (MTCC 11044), ide...

This paper examines the potential value of phosphate-solubilizing bacteria(PSB) in the dissolution of soil phosphorus and in the subsequent immobilization of lead (Pb), both in bacterial growth medium and in soil. In growth medium, Pseudomonas chlororaphis showed both phosphate-solubilizing and Pb-immobilizing capability, the immobilization of Pb was attributed to pyromorphite formation, as ind...

Abstract Background Wild potato species harbor a distinctive rhizosphere microbiome relative to their modern counterparts, thus providing competitive advantage for acquiring phosphorus (P) in native habitats. Despite this, the effects of transferring phosphorus-solubilizing bacteria (PSB), recruited from wild potatoes rhizosphere, on varieties’ performance has not been investigated. Here, it wa...

an experiment was conducted at assossa agricultural research center (aarc) station during 2008 cropping season in order to study the effects of co-inoculation of bradyrhizobium japonicum (tal-378 and tal-379) and phosphate-solubilizing bacteria (psb) (pseudomonas spp.), and conventional farmers’ fertilizer level (combined and individual application of 46n kg ha-1 and 46 p2o5 kg ha-1) on nodulat...

Experiments were conducted to evaluate the potential of phosphate solubilizing bacteria (PSB) Bacillus megaterium and potassium solubilizing bacteria (KSB) Bacillus mucilaginosus inoculated in nutrient limited soil planted with eggplant. Results showed that rock P and K materials either applied singly or in combination did not significantly enhance soil availability of P and K. PSB increased hi...

in order to investigate the integration of phosphorus fertilizer different levels and phosphorus solubilizing bacteria p.fluorescens on quantitative and qualitative forage yield of two fall barley cultivars, an experiment carried out at research farm of college of agriculture of university of tehran during 2009-2010. the experiment design consisted of three randomized complete blocks in a facto...
