Bamboo plant is a potential source of growth promoting bacteria (PGPB). Phosphate solubilizing ability an important characteristic PGPB. This study aims to isolate phosphate around the bamboo clumps using natural media. The are trapped media consist 70 gram cooked rice and banana peel. were stored in plastic boxes with four types treatments: 1) tightly closed, 2) covered tissue, 3) leaves, 4) u...

Abstract The aim of this study was to isolate and characterize the Phosphate solubilizing bacteria from rhizosphere Zea mays L., Jeneponto Regency. This research conducted in several stages; i.e, sampling, medium preparation, sample dilution, isolation, characterization form gram staining, biochemical tests, quantitative tests phosphate solubility. Soil samples were diluted 0.9% NaCl soil conta...

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...

introduction canola is the world third oil crop with 25 to 55 percent oil content (hezbavi & minaei, 2008). in recent years, tendency towards expansion of the acreage of canola in iran has been increasing and for the years 2010-2011 an area of 93000 ha with a total production of 190000 tons has been reported (ministry of jihad of agriculture, 2013). application of biological fertilizers which a...

Background and Objectives Alkaline pH of the soil facilitates the conversion of phosphate present in phosphate fertilizer applied in the field to insoluble phosphate which is not available to plants. Problem of soluble phosphate deficiency arises, primarily due to needless use of phosphate fertilizer. We sought to biofertilizer with the thermo-tolerant phosphate solubilizing actinomycetes conso...

A mineral phosphate solubilizing bacterium, Burkholderia cepacia DA23 has been isolated from cultivated soils. Phosphate-solubilizing activities of the strain against three types of insoluble phosphate were quantitatively determined. When 3% of glucose concentration was used for carbon source, the strain had a marked mineral phosphate-solubilizing activity. Mineral phosphate solubilization was ...

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 ...

Pesticide residues contributing to the contamination of soil may influence microbial population of the soil and in turn fertility of soil. The present paper reports the effect of pesticides applied to soybean i.e. phorate, carbofuran, carbosulfan, thiomethoxam, imidacloprid, chlorpyriphos and monocrotophos on soil microflora. The viable count of rhizobia and phosphate solubilizing bacteria from...
