Since 1960's, many kinds of microorganisms have been reported which are able to utilize various kinds of hydrocarbons and their derivatives. These microorganisms have been considered to be useful for their abilities of not only decomposing various organic pollutants in natural environment but also producing cellular materials and metabolites.
Recently, however, decreased number of the reports appear to be published on the fermentations performed with hydrocarbons as substrate, mainly because of the elevated cost of those substrates.
Thus, the investigations of hydrocarbon fermentation are now focused on the products which are formed from hydrocarbons in preference to conventional substrates such as carbohydrates, and some of them, for example, the production of long chain dicarboxylic acids are already industrialized.
In this review, recent papers on the microbial utilization of gaseous hydrocarbons, long chain aliphatic and isoprenoid hydrocarbons and their derivatives are summarized, especially from the applied point of view.
