Abstract:
A process for eliminating the flatulent sugars present in soya which comprises preparing an aqueous soya suspension containing from 5 to 45% by weight of dry matter, inoculating the suspension thus prepared with at least one strain of Saccharomyces uvarum which has reached the state of growth on a medium containing at least one sugar having at least one .alpha.-D-galactopyranosyl bond and fermenting the suspension under anaerobic conditions for at least 8 hours at a temperature of from 15.degree. to 50.degree. C.

Abstract:
A process for the preparation of zeaxanthin which comprises culturing a microorganism of the genus Flavobacter producing this pigment, in a nutrient medium containing at least one carbohydrate as assimilable carbon source, at least one source of assimilable amino nitrogen containing free amino acids, mineral salts, oligoelements and vitamins, the spectrum of amino acids of the medium being modified by increasing the content in the medium of at least one of the sulphur-containing amino acids methionine, cystine and cysteine, in relation to the content in the medium of other amino acids, whilst limiting the quantity of the sulphur-containing amino acid added to the medium to a value not exceeding 1 mg/ml, and continuing culturing until a substantial quantity of intracellular zeaxanthin has been obtained.
