Abstract: A process for the preparation of aqueous solutions of glucans having a β-1,3-glycosidically-linked main chain and side groups having a β-1,6-glycosidic bond by fermentation of fungal strains. The fungal strains secrete the glucans into the fermentation broth, in an aqueous culture medium, and the separation of the glucans from the fermentation broth is effected using asymmetrical filter membranes.

Abstract: Riboflavin is removed from fermentation suspensions by them being heated at from 50.degree. to 90.degree. C. for from 1 to 3 hours, than cooled to from 0.degree. to 30.degree. C. over a period of from 1 to 5 hours, and subsequently being centrifuged to give a sediment fraction and liquid fraction in such a way that the sediment fraction contains predominantly riboflavin crystals as solid, and the liquid fraction contains virtually no crystalline riboflavin, and, where appropriate, resuspending the sediment fraction in from 0.5 to 2 parts by volume of water per part by volume of sediment fraction and repeating procedure c.
