[Also in Division A5] A solution of an antibiotic e.g. griseofulvin in a hydrocarbon is obtained by culturing an antibiotic-producing strain of a microorganism under aerobic conditions in the presence of an aqueous nutrient medium containing a source of assimilable nitrogen and nutrient salts, in the presence of a source of assimilable carbon and in the presence of a hydrocarbon solvent medium, and recovering a solution of the antibiotic in said hydrocarbon solvent medium, said antibiotic-producing strain of microorganism being one producing an antibiotic having a solubility in the hydrocarbon solvent medium greater than 1 milligram per litre. The hydrocarbon solvent medium is a petroleum hydrocarbon fraction boiling in the kerosene or gas-oil range especially gas oil. Such fractions may also be capable of acting as sources of assimilable carbon during cultivation and may provide the main source of carbon and also act as solvent for the antibiotic produced. The constituents of the nutrient medium are otherwise conventional ones. A two-stage process wherein first a carbohydrate and then a hydrocarbon fraction is used as source of carbon may be used. In a modification, a microorganism such as yeast, which is capable of growing in a petroleum hydrocarbon fraction, is cultivated in an aqueous nutrient medium containing N, nutrient salts and said hydrocarbon fraction, the used aqueous nutrient medium is separated from the broth and, together with a petroleum hydrocarbon fraction, is added to an aqueous nutrient medium containing N and nutrient salts and the antibiotic-producing microorganism is cultivated therein. The griseofulvin producing microorganism may be Penicillium griseofulvum ATCC 11885, Penicillium patulum ATCC 10120 or Penicillium nigricans ATCC 9439. The solution of griseofulvin in a petroleum hydrocarbon fraction obtained as above may be used as an agricultural fungicide. (See Division A5).
