The mode of succinate mediated repression of mineral phosphate solubilization and the role of repressor in suppressing phosphate solubilization phenotype of two free-living nitrogen fixing Klebsiella pneumoniae strains was studied. Organic acid mediated mineral phosphate solubilization phenotype of oxalic acid producing Klebsiella pneumoniae SM6 and SM11 were transcriptionally repressed by IclR...
background and objectives: azotobacter is a diazotroph bacterium reported to possess various plant growth-promoting characteristics.the aim of this study was to isolate azotobacter strains capable of fixing nitrogen and effectively hydrolyzing both organic and inorganic pi compounds. materials and methods: in this study, soil samples collected from a diverse range of slightly alkaline soil type...
Phosphate solublization activity of Bacillus subtilis in different carbon and nitrogen sources with insoluble form of phosphate sources like tricalcium phosphate and rock phosphate were studied. TCP solubilization with different carbon sources irrespective of incubation period can be related in the following order: glucose, fructose, arabinose, mannose, sucrose, lactose, and sorbitol. The pH dr...
The rhizosphere is the area around the root of a plant occupied by a unique population of usefulbacteria known as plant growth promoting rhizobacteria (PGPR). In this study, the isolation andidentification of rhizobacteria from orange (Citrus sinensis) orchards using 16S rRNA gene, as well asbiological and biochemical assays is reported. Analysis of 16S rRNA gene was confirmed bybiological and ...
A study was performed to investigate the efficiency of rhizobacteria on solubilization of rock phosphate and their assimilation by wheat plants in quartz sand potted experiments. Two phosphate solubilizing bacteria, P. fluorescens and Serratia sp. were encapsulated in sodium alginate and potato starch beads and selected to investigate the variation on pH values, the enzymatic activity of alkali...
Phosphorus is one of the major components required for the metabolic activities and for the growth of any organism. Many soil organisms are known to solubilize inorganic phosphates. Aspergillus niger isolated from the soil showed extensive solubilization of Tri-calcium phosphate.It was observed that the solubilization was due to drop in pH.Acidification was due to production of organic acids by...
The present study was carried out in order to establish a suitable protocol for the screening of phosphate solubilizing actinomycetes. 10 isolates with distinct morphology were isolated and purified on starch casein agar from forest soils of Mahabubnagar district, Andhra Pradesh. These isolates screened for phosphate solubilizing activity on modified starch casein agar which contains tricalcium...
The use of phosphate solubilizing bacteria as inoculants simultaneously increases P uptake by the plant and crop yield. Strains from the genera Pseudomonas, Bacillus and Rhizobium are among the most powerful phosphate solubilizers. The principal mechanism for mineral phosphate solubilization is the production of organic acids, and acid phosphatases play a major role in the mineralization of org...
the iranian thymus daenensis subsp. daenensis is rich in monoterpene phenols (especially thymol and carvacrol). this research was conducted to isolate and characterize the plant growth promoting rhizobacteria (pgprs) from rhizosphere of t. daenensis. pgprs were screened based on some physiological traits including iaa production, phosphate solubilization, and siderophore compounds production ab...
