| Summary, etc. |
Phosphate solubilizing bacteria are capable to release inorganic phosphate and make it available to plants for growth enhancement. <br/>In this study, Serratia marcescens PH1, which has been isolated from tomato plant rhizosphere, has been subjected to different physical <br/>and chemical parameters for optimization of its phosphate solubilisation capacity. The best temperature, inoculum percentage, agitation rate, <br/>incubation time, and pH value were found to be 30?, 1.5%, 150rpm, 5 days, and 7-8, respectively. The best carbon source for phosphate <br/>solubilisation among 5 different sources, glucose, sucrose, galactose, maltose, and arabinose, was glucose which allows for releasing <br/>797mg/L of P. Besides, casein was the best nitrogen source for phosphorus release (853mg/L) and Ca3(PO4)2 in Pikovskaya medium was the <br/>best P source (855mg/L). The key factors affecting P release in the modified Pikovskaya medium were glucose, casein and inoculum percentage. <br/>P concentration in the modified Pikovskaya culture medium was 853mg/ml comparing with only 749mg/L in the classical formula. For freeing of P, <br/>Serratia marcescens PH1 produces organic acids such as citric, lactic, malic, and benzoic acids. Phosphorus yield was increased gradually with <br/>organic acids production till reaching 861mg/ml in 5 days with pH drop to 1.1. pqqC (a gene responsible of PQQ production) gene fragment <br/>of approx. 568 bp was successfully amplified in phosphate solubilizing bacteria. Detection of pqq genes is an evidence of gluconic acid <br/>production capability. This acid is a well known biocontrol agent. Serratia marcescens PH1 is a strong phosphate solubilizer and we are planning <br/>to conduct more wide-scale experiments in pots to optimize the utilization of such bacterium before conducting agricultural applications as a plant <br/>growth promoter and a biocontrol agent<br/> |
