tailieunhanh - Condition optimization for phosphate solubilization by Kosakonia cowanii MK834804, an endophytic bacterium isolated from Aegle marmelos

In the present study endophytic bacteria were isolated from Aegle marmelos and were screened for phosphate solubilizing activity. The isolate AP01 showed the ability to solubilize inorganic tricalcium phosphate and thus was characterized. Phenotypic, biochemical and genotypic analysis revealed, the isolate to be Kosakonia cowanii, a gram –ve proteobacterium of family enterobacteriaceae with accession no. MK834804, of the three media viz. Pikovskaya’s agar (PKVA), National Botanical Research Institute’s phosphate growth medium (NBRIP) and NBRIP-BPB (Bromo Phenol Blue) agar media tested for Phosphate solubilizing efficiency, the isolate showed high Phosphate solubilizing Index (PSI ) in PKVA medium. Whereas, under submerged fermentation the isolate showed highest phosphate solubilization in NBRIP medium () on 4 th day with maximum drop down of medium pH (). Optimum solubilization of phosphorus was observed at temperature 37ºC (), pH 8 ( µg/ml) with % ammonium sulphate () and 2% Lactose () on 4th day of incubation period as optimal nitrogen and carbon sources respectively. Release of various organic acids . oxalic acid, malic acid, tartaric acid and gluconic acid into the medium was characterized by High Performance Liquid Chromatography (HPLC), during phosphate solubilization by the isolate. | Condition optimization for phosphate solubilization by Kosakonia cowanii MK834804, an endophytic bacterium isolated from Aegle marmelos
