The rate of microbial degradation of oil in a beach gravel column

  title={The rate of microbial degradation of oil in a beach gravel column},
  author={C. F. Gibbs and Steven J. Davis},
  journal={Microbial Ecology},
An automatic, continuous flow respirometer was used to follow the bio-oxidation of a crude oil in a column of fairly coarse beach material. A number of water percolation rates were employed, with and without inorganic nutrient supplementation (nitrate and phosphate). Initially, nutrient supplementation was required to allow significant oxidation rates, but a capacity for biodegradation in the absence of continued supplementation developed slowly. The increase in oxidation rate with nutrient… CONTINUE READING
