title: Oxidation of gaseous and volatile hydrocarbons by selected alkene-utilizing bacteria.
abstract: Eleven strains of alkene-utilizing bacteria belonging to the genera Mycobacterium, Nocardia, and Xanthobacter were tested for their ability to grow with C(1) to C(6) alkanes, C(2) to C(6) alkenes, alkadienes, and monoterpenes furnished individually as sole sources of carbon and energy in a mineral salts medium. A limited number of alkenes and alkanes supported growth of the bacteria; some bacteria were unable to grow on any of the saturated hydrocarbons tested. Monoterpenes were frequently used as carbon and energy sources by alkene-utilizing bacteria belonging to the genera Mycobacterium and Nocardia. Washed cell suspensions of alkene-grown bacteria attacked the whole range of alkenes tested, whereas only three strains were able to oxidize alkanes as well. The alkenes tested were oxidized either to water and carbon dioxide or to epoxyalkanes. Few epoxides accumulated in stoichiometric amounts from the corresponding alkenes, because most epoxides formed were further converted to other compounds like alkanediols.
