Compared with 3 strains capable to produce IAA, 12 strains exhibited the trait to solubilize
These pesticides due to persistence in the soil and also through direct exposure, harm the activities of bacteria which are able to solubilize
The aim of this test is the evaluation and appreciation of the ability of the isolates to solubilize
various forms of inorganic P.
The strategies include either solid form manipulation using amorphous, salt or cocrystal form, or solvation methods using materials that can solubilize
the drug compound such as cosolvents, surfactants or cyclodextrins.
The relationship between pH reduction and increased K availability were observed by other authors (Lopes-Assad et al., 2006; Girgis et al., 2008), suggesting that the pH decrease, usually associated with the production of different organic acids, may be one of the mechanisms used by these bacteria to solubilize
the mineral and release the K present in their crystalline structure.
However, all the selected isolates were able to solubilize
TCP in NBRIP agar media.
From the chemical chelates EDTA seem to propose the best potential to solubilize
Pb and Cr For Cu and Cd the effectiveness of DTPA is the highest Fungal species were weak in competition with the chemical chelates, but provided an alternative for remediation in form of adsorbing the heavy metals in their biomass.
For example, certain drugs, such as the alkaloids, are notoriously difficult to solubilize
. There is a need for improved methods for delivering drugs with adequate bioavailability, bioactivity, and ease of use, with reduced side-effects.
Since the direct measurement of P solubilization in broth assay is likely to give more reliable results than regular plate assay, isolates were also tested for their ability to solubilize
tricalcium phosphate (TCP) in NBRIP medium at 24 h, 48 h, and 72 h and were found to solubilize
tricalcium phosphate with an increase from 24 h to 72 h in case of PB-09 while for other isolates it increases upto 48 h then it remains constant.
Microorganisms belonging to the genera Pseudomonas, Bacillus, Rhizobium, Azotobacter and Azospirillum, among others, frequently have the ability to solubilize
phosphorus (Rodriguez and Fraga, 1999).
Strong binding abilities of oxalic and citric acids have been proven as the most competent agents to solubilize
soil P .
Microbes which solubilize
the bound phosphates and rock phosphates are called phosphate solubilizing microorganisms.
