Biodegradation of phenol in laboratory-contaminated soils by the gram positive soil bacterium Corynebacterium glutamicum have been investigated. This study showed that phenol degradation by C. glutamicum was greatly enhanced by the addition of 1 % yeast extract. From toxicity test using Daphnia magna, phenol removed soil by C. glutamicum was not revealed hazardous anymore. In addition, treatment of C. glutamicum to the phenol contaminated soils alleviated various soil amino acids compositions such as glycine, threonine, isoleucine, alanine, valine, leucine, tyrosine, and phenyl alanine. The phenomena induced increasing seed erminate
rate and root elongation of Avena sativa (oat). We conclude that the phenol contaminated soil was effectively fertilized through increased soil amino acid compositions as well as the phenol in soil environment was biodegraded by C. glutamicum.
