Abstract

Fats or fat-soluble lipids are obtained by a process in which bacteria, yeasts or moulds which require i-inositol for normal growth are cultured in a nutrient medium containing carbohydrate, such as glucose or sucrose, as the principal constituent, but containing less i-inositol than is required for the normal growth of the organism, whereafter fat is extracted from the organism, suitably by solvent extraction or by mechanical means. Suitable organisms are the yeasts of the genus Saccharomyces, such as S. cerevisiae W.S., S. carlsbergensis Strain M, S. carlsbergensis 4228, and of the genus Kloeckera such as K. brevis. The culture is best carried out under aerated conditions in a specified nutrient solution containing a nitrogen source, salts, trace elements, and growth factors in addition to the sugar, if desired in the complete absence of i-inositol. Specifications 146,430 and 146,431, [both in Class 91], are referred to.ALSO:Fats or fat-soluble lipids are obtained by a process in which bacteria, yeasts, or moulds, which require i-inositol for normal growth, are cultured in a nutrient medium containing carbohydrate, such as glucose or sucrose, as the principal constituent, but containing less i-inositol than is required for the normal growth of the organism, whereafter fat is extracted from the organism, suitably by solvent extraction or by mechanical means.
