L-Glutamic acid is produced by culturing a hydrocarbon non-assimilating micro-organism capable of producing L-glutamic acid in an aqueous nutrient medium containing a source of carbon and nitrogen and inorganic salts under aerobic conditions in the presence of at least one hydrocarbon. Specified hydrocarbons are straight- and branched-chain paraffins, cycloparaffins, straight- and branched-chain olefins, cycloolefins, aromatic hydrocarbons and mixtures thereof, and mixed hydrocarbons such as kerosene, light oils or paraffin oils. Specified microorganisms are various strains of Micrococcus glutamicus. Examples are given which show the effect of various hydrocarbons on the amount of L-glutamic acid produced.
