Phosphate solubilization by endophytic bacteria isolated from Oryza sativa

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.
