Corynebacterium glutamicum is industrially useful organism for production of amino acid. In addition, C. glutamicum is able to utilize various aromatic compounds such as phenol, catechol and naphthalene as a sole carbon source. In this study, C. glutamicum was cultured in a mineral salt medium containing 1% yeast extract without any additional carbon sources. It was found that when C. glutamicum was added to soil contaminated with phenol and naphthalene, amino acid was synthesized by degradation of aromatic compounds through the intermediate analysis by HPLC. In addition, the useful amino acids synthesized in soil were confirmed by seed germination and root elongation. Finally, this work suggests that C. glutamicum can be applied to the environment-benign fertilization technology for aromatic compounds-contaminated soils. |
