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 study was undertaken to determine the effects of different biofertilizers on growth and seed barley, Bahman cultivar in Iran. The trial was laid out in RCBD with split plot arrangement having three replications during 2011-12 and at Boroujerd, Iran. Treatments were three nitrogen biofrtilizers (Nitroksin, Nitrokara and Supernitroplass) and three phosphate  biofrtilizers (Phosphate barvar2, Bi...

Drought stress is a major environmental stress that restricts plant growth and production in the majority of agricultural fields of the world. The application of different fertilizers, especially biofertilizers and organic fertilizers, might play an important role in the production of medicinal plants in order to improve their resistance to deficit water stress. In order to evaluate the effects...

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...

in order to study the effect of biological and chemical fertilizers of nitrogen and phosphorus on some physiological, morphological and phenological traits of sunflower this study was carried out in eivanegharb (ilam province) in summer of 2011. treatments were arranged in split factorial based on rcbd with three replications. the main plot include 4 levels of phosphorus and nitrogen chemical f...

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...

in order the the effect of biofertilizer and cut irrigation on growth of borage (borago officinalis) an experiment in split plot randomized based on complete block design with three replications in 1393 at the agricultural research station of roudehen islamic azad university done. treatments were first factor drought in four levels (control, stress at vegetative stage, stress at flowering stage...

Phosphorus solubilizing microorganisms are capable of transforming insoluble phosphorus (P) forms to soluble and bioavailable P. The aim of the present study was to isolate P solubilizing bacteria from forest soils around the rock phosphate (RP) mine of Koh-e-SepidLar in Kohgiluyeh and Boyer Ahmad province and evaluate their ability in Sperber culture medium and wheat straw medium in the presen...
