This study used a [(13)C]DNA stable isotope probing (SIP) technique to elucidate a direct pathway for the translocation of (13)C-labeled photoassimilate from maize plants to extraradical mycelium-associated phosphate-solubilizing bacteria (PSB) that mediate the mineralization and turnover of soil organic phosphorus (P) in the hyphosphere. Inoculation with PSB alone did not provide any benefit t...

Phosphate-solubilizing bacteria (PSB) can promote the dissolution of insoluble phosphorus (P) in soil, enhancing the availability of soluble P. Thus, their application can reduce the consumption of fertilizer and aid in sustainable agricultural development. From the rhizosphere of Chinese cabbage plants grown in Yangling, we isolated a strain of PSB (YL6) with a strong ability to dissolve P and...

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...

Organic farming is gaining popularity all over the world as it avoids the use of synthetic chemicals. Plant production in organic farming mainly depends on nutrient release as a function of mineralization processes in soils. In the present study, efficient phosphate mineralizing bacteria were isolated and their efficacy tested in plant mineral uptake and soil fertility of an organic field. Amon...

A promising solution for phytoremediation of metal-contaminated soils is to use plants in combination with phosphate-solubilizing bacteria (PSB). In this study, we subjected isolate PSB from paddy soil and investigate their ability improving the lead (Pb2+) by a weed plant (Echinochloa colona (L.) Link) as well promoting growth E. under Pb stress condition. Total 06 (labeled TB01 TB06) were iso...

Remediation of lead (Pb)-contaminated sites with phosphate amendments is one of the best studied and cost-effective methods for in situ immobilization. In this treatment, a very stable mineral, pyromorphite Pb5(PO4)3Cl, is formed. Several studies propose to improve this treatment method with the addition of phosphate-solubilizing bacteria (PSB). The effect of bacteria on solubilization of pyrom...

Arbuscular mycorrhizal fungi (AMF) and phosphate solubilizing Pseudomonas bacteria (PSB) could potentially interact synergistically because PSB solubilize phosphate into a form that AMF can absorb and transport to the plant. However, very little is known about the interactions between these two groups of microorganisms and how they influence the growth of each other. We tested whether different...

phosphorus (p) is one a nutrient elements for plant growth. in most soils has complex behavior and forms sparingly soluble compounds with soil particles. phosphorus bioavailability can be controlled by soil biological activities for optimum nutrition of plants. this study was carried out in order to isolation of p-solubilizing bacteria (psb) as well as p-solubilizing fungi (psf) and their scree...

Phosphate Solubilizing Bacteria (PSB) are known that have important role to improve plant phosphate uptake as biofertilizer. These Microorganism hold potential promote organic agriculture eco friendly and efficiency. This study aims isolate, enumerate characterize indigenous PSB from Kebunan Village soil the biofertilizer agent. Isolation enumeration were carried out using spread plate method o...
