Effect of petroleum on seed germination in Vigno radiata and its degradation by Pseudomonas fluorescens and Streptomyces isolates


Petroleum – degrading organisms has been isolated f rom a petroleum polluted site. Of the two isolates, the best degrader was selected on the basis of growth in liq uid and soild media supplemented with petroleum as sole carbon source. The isolates were identified as a Pseudomon as fluorescens and Streptomyces were further studied in batch culture for its petroleum degradation potential und er aerobic condition and was observed for seven day a, where loss in petroleum constituent was up to 75%. Germi nation and growth of Vigno radiata was significant ly enhanced in presence of the degrading microorganisms.
