Degradation of aromatics and saturates in crude oil by soil enrichments

Fedorak, P.M. | Westlake, D.W.S. (Alberta Univ., Edmonton (Canada). Dept. of Microbiology)
Soil was incubated in the presence of Prudhoe Bay crude oil at 20 deg C under shake-flask conditions. With the addition of N and P to the medium, the susceptibility of aromatic compounds to microbial degradation over an 11-day period was found to be: naphthalene approx. = 2-methylnaphthalene 1-methylnaphthalene dimethylnaphthalenes approx. = dibenzothiophene approx. = phenanthrene C(,3)-napthalenes methyl-phenanthrenes C(,2)-phenanthrenes. The n-alkanes and isoprenoids (pristane and phytane) were also extensively degraded during this time. The omission of N and P from the medium reduced the extent to which the culture degraded the n-alkanes but had little effect on the degradation of the aromatic fraction after a 27-day incubation period.
