Phosphate solubilization

Biocontrol of stem end disease agent, Alternaria alternata YZU, on pitaya is more interested in altering the application of chemical pesticides. This study was conducted to characterize antagonistic phosphate solubilizing bacteria (PSB) from rhizosphere soil for their biocontrol activities against A. alternata YZU under laboratory and greenhouse conditions.

These isolates were screened, in vitro, according to their capacities to produce plant growth promoting substance i.e. IAA, phosphate, potassium solubilization, chitinase activities and hydrogen cyanide. Results indicated that 36 bacterial isolates showed IAA production, 25 HCN production, 57 chitinase activities, 39 phosphate and 105 potassium solubilizers.

Vital factor towards increased plant growth was the amount of IAA secreted by the organism (i.e. 2.65 mg IAA/100 ml of the culture filtrate) which is reasonably high in comparison to earlier reports available. Furthermore, PSB has also demonstrated bioremediation potential against harmful heavy metals such as copper, lead, nickel and arsenic by tolerating upto 25 mM indicating it’s prospective in remediating heavy metal contaminated agricultural fields.

Beneficial biofilms developed by nitrogen fixing bacteria and P - solubilising fungi in vitro conditions and also used as biofertilizers in non - leguminous crops and also observed that the bacteria colonized fungal mycelia to form biofilms. The biofilms showed high rates of biological nitrogen fixation and organic acid production which directly influences the synthesis of indole acetic acid like substances than microbes when used as monocultures. (Seneiviratne et al., 2003).

Endophytic bacteria isolated from the Oryza sativa plant were evaluated for phosphate solubilisation. Five of these isolates that showed good phosphate solubilising activity were characterised at molecular level and tested for phosphate solubilisation using three different sources viz tricalcium phosphate (TCP), aluminium phosphate (AlPO4) and iron phosphate (FePO4). Based on 16s rRNA gene sequence analysis the isolates were identified as Pantoeaa ananatis, Pseudomonas putida, Brevibacillus agri, Bacillus subtilis and Bacillus megaterium.
