Abstract

A methodology was devised and was found useful for the selection of populations degrading recalcitrant hydrocarbons. The work was part of a programme aiming at developing knowledge of the intrinsic capacities of autochtonous microflorae of the environment for gasoline biodegradation. The methodology involved monitoring the progress of degradation in enrichment liquid cultures on the selected hydrocarbon by gas chromatographic analysis of CO2 production and O2 consumption. Populations degrading in particular o-xylene, 1,2,4-trimethylbenzene, cyclohexane were obtained. Concerning 2,2,4-trimethylpentane (isooctane), one microflora (and a pure strain derived from it) growing on this hydrocarbon were obtained from gasoline-polluted water.
