“…Gerretsen [1] initially demonstrated that microbiological activity in the rhizosphere can dissolve sparingly soluble inorganic P and increase plant growth. Several species of Aspergillus and Penicillium are known for solubilizing insoluble phosphates [2][3][4].…”

Response of Cold-Tolerant Aspergillus spp. to Solubilization of Fe and Al Phosphate in Presence of Different Nutritional Sources

Three species of Aspergillus, namely, A. niger, A. glaucus and A. sydowii, isolated from soil samples collected from the Indian Himalayan Region (IHR), have been investigated for solubilization of aluminium phosphate and iron phosphate in the presence of different carbon and nitrogen sources. Preference of each fungal species varied for nitrogen and carbon sources, in terms of phosphate-solubilization. Among three species, Aspergillus niger gave the best results; it solubilized 32% and 8% of the supplemented aluminium phosphate and iron phosphate, respectively. The results indicated that the effect of carbon and nitrogen sources can influence the phosphate solubilizing efficiency of all the three Aspergillus spp. tested. All the three species were found to be plant-growth promoters in bioassays conducted under greenhouse conditions. The Al and Fe phosphate solubilization efficiency, investigated in the present study, is at the lower end of their previously reported tricalcium phosphate solubilization efficiency. The cultures are likely to have better field applications in agrobiotechnology, due to their potential towards solubilization of Al and Fe phosphates, which are known to have lower solubility through microbial activity.

“…Among the alternatives that enable improvements in the efficient use of insoluble inorganic phosphates, we emphasise the action of microorganisms able to solubilise inorganic low soluble phosphates (Gerretsen, 1948;Sylvester-Bradley et al, 1982). The majority of studies looking at phosphate-solubilising microrganisms involve studies with fungi and free-living bacteria in the soil (Sousa et al, 2008;Bojinova et al, 2008;Linu et al, 2009;Ali et al, 2010).…”

Microbial solubilisation of low soluble inorganic phosphates is an important process contributing for the phosphorus available to plants in tropical soils. This study evaluates the ability of inoculant strains for tropical legumes to solubilise inorganic phosphates of low solubility that are found in tropical soils. Seven strains of Leguminosae nodulating bacteria (LNB) were compared with one another and with a non-nodulating positive control, Burkholderia cepacia (LMG 1222 T 3 . In liquid GELP medium, LMG 1222 solubilised all phosphate sources, but no legume nodulating strain could increase the solubility of Al(H 2 PO 4 ) 3 . The strains CIAT 899 and UFLA 02-100 were the only legume nodulating bacteria able to solubilise the other phosphate sources in liquid media, dissolving both CaHPO 4 and FePO 4 .2H 2 O. There was a negative correlation between the pH of the culture medium and the concentration of soluble phosphate when the phosphorus source was CaHPO 4 or FePO 4 .2H 2 O. The contribution of these strains to increasing the phosphorus nutrition of legumes and non-legume plant species should be investigated further by in vivo experiments.

“…Gerretsen (1948) showed that pure cultures of soil bacteria could increase the P nutrition of plants under controlled conditions through solubilization of precipitated forms of calcium (Ca) phosphates. Since this study, many examples of microbially mediated P mobilization and characterization of different microorganisms have been reported (for review, see Richardson, 2001;Gyaneshwar et al, 2002;Khan et al, 2007Khan et al, , 2010Harvey et al, 2009;Richardson et al, 2009a;Zaidi et al, 2009).…”
