Phosphate-solubilizing fungi (PSF) are able to enhance the solubilization of insoluble phosphate (P) compounds. They also have the capacity to mobilize and increase nutrient uptake, produce organic acids and increase the efficiency of phosphate fertilizers, such as superphosphate and rock phosphate (Jyoti et al., 2013; Li et al., 2015).

1948) [23] or tricalcium phosphate medium (Nautiyal, 1999) [22]. The primary screening protocol used for the identification of PSB strains usually depends on the use of tricalcium phosphate as a sole source of P in indicator plates. we decided to use tricalcium phosphate as source of P for screening of PSB isolated from rhizospheric soils.

Rock Phosphate (RP) is theoretically the cheapest fertilizer and most abundant, but its direct application in the soils is not always agronomically effective due to its low phosphorus (P) availability. An environmentally friendly and economically alternative to traditional processing of these deposits is the use of Phosphate Solubilising Microorganisms (PSM). …

Aims: Although phosphate solubilizing bacteria (PSB) have been globally reported to improve soil phosphorus (P) availability and plant growth, technical gaps such as the lack of an ideal screening approach, is yet to be addressed. The potential of non-halo-forming PSB remains underestimated because of the currently adopted screening protocols that exclusively …
