abstract many agricultural researches have been performed to improve soil productivity. nitrogen (n) and phosphorus (p) are essential elements which are utilized by the plants in large amounts. phosphorus can be provided by applying chemical fertilizers. microorganisms convert insoluble phosphate to the soluble form and some bacteria such as rhizobacteria play an important role in this process....

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...

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 ...

The interactive effect of phosphate-solubilizing bacteria and arbuscular mycorrhizal (AM) fungi on plant use of soil P sources of low bioavailability (endogenous or added as rock phosphate [RP] material) was evaluated by using soil microcosms which integrated (sup32)P isotopic dilution techniques. The microbial inocula consisted of the AM fungus Glomus intraradices and two phosphate-solubilizin...

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 ...

Pseudomonas lutea OK2(T) (=LMG 21974(T), CECT 5822(T)) is the type strain of the species and was isolated from the rhizosphere of grass growing in Spain in 2003 based on its phosphate-solubilizing capacity. In order to identify the functional significance of phosphate solubilization in Pseudomonas Plant growth promoting rhizobacteria, we describe here the phenotypic characteristics of strain OK...

phosphate solubilizing bacteria are a group of plant growth promoting rhizobacteria (pgpr) that increase growth and yield of plant by enhancing insoluble phosphates. in this study, a greenhouse experiment was carried out to investigate the effect of phosphate solubilizing bacteria and phosphorous fertilizer on the yield and chemical components of sesame. this experiment was conducted in factori...

Alleviating plant salt stress and remediating saline soils are of great economic interest. Beneficial microbes such as Arbuscular Mycorrhizal (AM) fungi, Plant Growth Promoting Rhizobacteria (PGPRs), etc. are associated with many plants including trees. These beneficial microbes can cope up with salinity and help the plants to survive in such soils. In this study, diversity status of beneficial...

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...
