Abstract-The degradation dynamics of phenanthrene in soil was To evaluate the role of microbial degradation in the
studied. The half-life of phenanthrene in the non-sterilized disappearance of phenanthrene in contaminated soil, the
contaminated soil was only d, much shorter than the same in phenanthrene degradation runs with a starting concentration of
the sterilized soil. The dominant strain of phenanthrene microbial 50 mg/kg in sterilized and non-sterilized soil were conducted in
degradation was isolated and identified by 16S rDNA as a biochemical incubator at 30 ℃.
Alcaligenes sp.; its growth and degradative capability were highest
at 25 ℃ and pH of . Inoculation of the dominant strain to soil B. Analytical procedures
enhanced phenanthrene degradation, and faster degradation rates
were observed with larger doses of the strain inoculated. The phenanthrene concentrations of experimental samples
were analyzed by gas c
