Chemical biotechnology for the specific oxyfunctionalization of hydrocarbons on a technical scale.

Bruno Bühler et al.

Biotechnology and bioengineering, 82(7), 833-842 (2003-04-18)

Oxygenases catalyze, among other interesting reactions, highly selective hydrocarbon oxyfunctionalizations, which are important in industrial organic synthesis but difficult to achieve by chemical means. Many enzymatic oxygenations have been described, but few of these have been scaled up to industrial

Selection of microbial populations degrading recalcitrant hydrocarbons of gasoline by monitoring of culture-headspace composition.

F Solano-Serena et al.

Letters in applied microbiology, 30(1), 19-22 (2000-03-23)

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.
