Abstract

Micro-organism belonging to one of the genera Saccharomyces, Pichia, Saccharamycopsis, Rhodotorula, Candida, Torulopsis or Trichosporon is cultivated under aerobic conditions in a nutrient medium which can be assimilated by the micro-organism and contains carnitine, one of its precursors or derivs. Suitable micro-organisms are Saccharomyces cerevisiae or rouxii, Pichia farinosa or membranaefaciens; Saccharomycopsis lipolytica; Rhodotorula rubra; Candida novellus, tropicalis, lipolytica, arborea, guillemondii or rugosa, etc. The nutrient medium pref. contains a C source e.g. sugars, oils, fats, alcohols, org. acids or hydrocarbons. Suitable precursors of carnitine are crotono- and butyro- betaine and suitable derivs. are acetyl- propionyl-, butyryl-, palmitoyl- and stearoyl- carnitine. The speed of cell growth is increased, thus shortening the process time, increasing the yield and avoiding the danger of contamination.
