“…This showed the importance of endophytic P. dispersa as a modulator of root and shoot development in rice seeds. Chen et al (2014) reported that P. dispersa was isolated from cassava (Manihot esculenta) roots. Furthermore, this bacterium has been shown to facilitate the solubilisation of phosphate which enables host plants to acquire more phosphorus in red acidic soils.…”

“…Under salt stress Phosphate precipitate out and become unavailable for plant growth. PGPR induced P solubilization to make available P is another mechanism of PGPR to alleviate salt stress (Sharma 2013a;Chen et al, 2014;Paul & Sinha, 2017). Many authors have reported that PGPR also secrete phosphate enzyme which solubilize inorganic phosphate which is easily taken up by plant roots and elicit a strong growth promoting effect on plants grown under saline condition (Sharma, 2013b;Kadmiri et al, 2018).…”

A field experiment was conducted to investigate the effect of PGPR inoculation on growth and yield of maize as well as on reclamation of saline sodic soil of Soil Salinity Research Institute Pindi Bhattian Pakistan, during 2015-16. Seed of maize genotype "Islamabad Gold" were soaked (2-3 h) prior to sowing in the broth culture of 4 bacterial strains i.e. Pseudomonas putida (accession no. KX580766), Pseudomonas fluorescens (accession no. KX644132), Exiguobacterium aurantiacum (accession no. KX580769), Bacillus pumilus (accession no. KX580768) and Lysinibacillus sphaericus (accession no. KX580767). In vitro analysis of bacteria confirmed that they metabolize ACC deaminase, solubilize insoluble phosphate and produce significant quantity of auxin in the presence of L-tryptophan. Inoculation of maize with bacteria along with application of 1L inocula / treatment in the field gave a significant (P = 0.05) increase in germination (76%), leaf chlorophyll (24%), proline (65%), anthocyanin (38%) and soluble sugar content (56%). P. putida inoculation resulted in maximum increase in plant height, leaf area, no of grains cob -1 (459.8), 1000 grain weight (330.9 g) and grain yield (3.25 tha -1 ). P. fluorescens was least effective. The rhizosphere soil analysed after harvesting exhibited significant decrease in electrical conductivity (49%), sodium absorption ratio (98%), and cation exchange capacity (94%) concomitant with a significant increase in organic matter (52%), NO3-N (37%), available P (48%) and K (31%). The highest efficiency of P. putida may be attributed to the maximum ACC deaminase activity, higher production of indole acetic acid and greater potential for Phosphate solubilization. The favorable effects of PGPR were more pronounced in the successive year 2016.

“…For example, Chen et al. proved that soil application of Pantoea dispersa triggered natural soil microbial activity and that this phenomenon could be maintained up to 25 days, suggesting that the endophyte P. dispersa would be a suitable candidate for optimizing agro‐microecological systems via soluble P release in soil . After 5 days, the application of P. dispersa to unsterilized soil increased the soil soluble P to 0.98 mg kg ‐1 , which was 2.10 times higher than that of the control .…”

This paper presents the results of in situ studies on solubilization of different phosphorus-bearing raw materials by application of natural ability to produce organic acids by Bacillus megaterium. Poultry bones as well as fish bones were used as renewable sources of phosphates. Morocco phosphorite was used as nonrenewable sources of phosphates. Glass columns, filled with the soil mixed with different doses (1, 5, and 10%) of mentioned sources of phosphorus, were used as a medium for solubilization. It was found that the amount of released phosphorus (determined in the eluent and expressed as P 2 O 5 ) significantly increased in the cases of columns where B. megaterium was used, when compared with the control group (without microflora). Higher doses of phosphorus-bearing material used in the experiment influenced in the release of higher amount of phosphorus. The highest effectiveness of solubilization was found in the case of poultry bones. The experiment was repeated for poultry bones but with the supplementation of nutrients. It was found that the delivery of nutrients had a strong effect on the increase of effectiveness of solubilization. Two times higher amount of phosphorus (express as P 2 O 5 ) was released from the hydroxyapatite structure of bones. It was confirmed that poultry bones could serve as a source of phosphates in microbial solubilization performed in in situ.
