Phosphorus (P) plays a vital role in many aspects of plant growth and development. The low amount available P agricultural soils reduces crop productivity phosphate fertilizers are often applied. However, due to the high affinity for soil constituents, availability this element becomes limited plants. Thus, alternative, ecological, low-cost techniques have been studied improve acquisition by cr...

The present study was conducted to isolate phosphate solubilizing bacteria (PSB) from rhizospheric saline soils of coastal Odisha, India and evaluated their ability. Total four PSB were isolated based on the halo zone formation (solubilizing index 2.63-3.14) PVK agar medium characterized biochemical molecular characteristics as Bacillus subtilis (B1), B. megaterium (B2), Sphingomonas paucimobil...

to evaluate the inoculation effect of potassium releasing, phosphate solubilizing and nitrogen fixing bacteria on the fruit quality of tomato, an experiment based on randomized complete block design with 9 treatments and 3 replications has been conducted. in this experiment, tomato (super chief cv.) seedlings of the in the treasury cultivation with single and combined treatments of the potassiu...

Biofertilizers have been used as sources to improve plant nutrients in sustainable agriculture. Experiments were conducted to evaluate the potential of phosphate solubilizing bacteria (PSB) Bacillus megaterium var. phosphaticum and potassium solubilizing bacteria (KSB) Bacillus mucilaginosus inoculated in nutrient limited soil planted with pepper and cucumber. Results showed that rock P and K a...

A study was conducted at Universiti Putra Malaysia to determine the effect of phosphate-solubilizing bacteria (PSB) and organic acids (oxalic & malic) on phosphate (P) solubilization from phosphate rock (PR) and growth of aerobic rice. Four rates of each organic acid (0, 10, 20, and 30 mM), and PSB strain (Bacillus sp.) were applied to aerobic rice. Total bacterial populations, amount of P solu...

Heavy metal pollution of soils is of great concern. The presence of the toxic metal species above critical concentration not only harmfully affects human health but also the environment. Among existing strategies to remediate metal contaminates in soils, phytoremediation approach using metal accumulating plants is much convincing in terms of metal removal efficiency, but it has many limitations...

A total of 28 samples were processed, of which 20 isolates were identified as phosphate solubilizing bacteria. Among 20 isolates, 12 (60 %) belonged to B. subtilis, 3 (15%) were B. brevis, 3 (15%) belonged to Pseudomonas aeruginosa and 2 (10 %) were identified as Enterobacter aerogenes. All the isolates exhibited phosphate solubilization (1.009 μg/ml to 1.609 μg/ml), produced Indole acetic acid...

Plants always interact with microorganisms either negatively or positively during their life cycle. The Phosphate Solubilizing Bacteria (PSB) group is one example that has some beneficial effects on the plant. PSB can transform insoluble soil inorganic phosphates into soluble phosphorous so plants absorb them. This research aimed to test isolate's ability solubilize and use 16S rRNA marker gene...

Phosphorus (P) deficiency in soil limits crop yields and can be managed by P fertilizers. But mere applying fertilizers alone may not effective justifying its bioavailability. At present global reserves are declining an increasing way which urges us to find out alternatives. Thus, the work was taken prepare phosphocompost using water hyacinth (Eichhornia crassipes) as feedstock, termite, normal...
