Four hundred isolates obtained from soil samples collected from forest, river basin, agricultural fields and rhizosphere of plantation crops of North Bengal were screened for phosphate solubilizing activity on Pikovskaya’s agar medium. Among the screened isolates, ninety showed phosphate solubilizing activity. Out of these, ten isolates belonging to Aspergillus niger, A. melleus and A. clavatus...

Phosphate fertilization is a common practice in agriculture worldwide, and several commercial products are widely used. Triple superphosphate (TSP) is an excellent soluble phosphorus (P) source. However, its high cost of production makes the long-term use of crude rock phosphate (RP) a more attractive alternative in developing countries, albeit its influence on plant-associated microbiota remai...

Endophytic bacteria are responsible for improved plant growth due to its role in nitrogen fixation, indole acetic acid (IAA) production, phosphate solubilization etc and protection through various mechanisms production of bioactive compounds. The purpose this study was determine the promoting potential endophytic isolated from medicinal plants namely, Adulsa, Amla, Bael, Kadamb, Mango, Neem, Tu...

Drought is one of the most detrimental environmental stressors to plants with potential decrease crop yields and affect agricultural sustainability. Native bacteria beneficial traits enhance plant growth help avoid reverse effects drought in a greater extent. In present study, we aimed ( i ) isolate drought-tolerant Bacillus isolates from rhizosphere soil wheat grown at different locations Jais...

Abstract To fulfils the demand of melons ( Cucumis melo ), it requires intensive maintenance by agrochemical products. If this is done continuously, will lead to soil degradation and disrupt sustainable food supply. Therefore, an innovation needed maintain supply using biofilm biofertilizer technology. This study aims are determine potential bacteria isolated from melon rhizosphere solubilize p...

Endophytes are growth-promoting agents capable of synthesizing phytohormones, uptaking nutrients, and controlling pathogens. There is a strong potential to exploit them in the agriculture field like biofertilizers biocontrol agents. In this work, we aimed evaluate endophytic fungi isolated from Pachystachys lutea for their solubilize phosphate, synthesise indole acetic acid (IAA), antagonize ph...

Background: The present scenario of agriculture is dependent on chemical fertilizer, pesticides and artificial growth promoters etc. extensive uses these chemicals fertilizers affect soil it become less fertile. These problem requireaying an attention towards the use native biological agents for endorsement plant growth. Indigenous rhizobacteria are rhizospheric bacteria having ability to enhan...

A diluted solution of a mixture of Hb S and Hb A in concentrated phosphate buffer was found to aggregate with a clear demonstration of delay time. The mechanism of the participation of Hb A in the aggregation of deoxy Hb S in concentrated phosphate buffer has been investigated. Both the delay time and the aggregation time in the polymerization reaction of mixtures of Hb A and Hb S were prolonge...

Mangrove seedlings were treated with a mixture of two bacterial species, the slow-growing, N(2)-fixing bacterium Phyllobacterium sp. and the fast-growing, phosphate-solubilizing bacterium Bacillus licheniformis, both isolated from the rhizosphere from black, white, and red mangroves of a semiarid zone. Nitrogen fixation and phosphate solubilization increased when the mixture was used compared t...

Phosphorus deficiency is a major constraint to crop production due to rapid binding of the applied phosphorus into fixed forms not available to the plants. This work was carried out to explain the release of soluble phosphates and its effect on plant growth as a function of phosphate solubilization by fluorescent Pseudomonas. In the current study, Pseudomonas fluorescens K 34 solubilized trical...
