    Abstract: A suspension of yeast cells is prepared, the cells are mechanically disintegrated and subjected to autolysis, autolysis being intensified by the addition of proteolytic enzymes. A sulphite is added to the yeast suspension before or after the mechanical disintegration step, the insoluble fractions are separated from the hydrolysed suspension, a compound of calcium is added to the supernatant liquid and the supernatant liquid is clarified. The process produces low-salt yeast extracts.

    Abstract: Biosynthesis of lycopene is effected by (a) treating a microorganism of the genus Flavobacter with 1-methyl-3-nitro-1-nitrosoguanidine (I) in a solidified nutrient medium contg. sucrose as C source to produce a lycopene-producing nutant; and (b) culturing the nutant in an aq. nutrient medium. The initial flavobacter strain is pref. ATCC 21588.Lycopene is a natural red pigment (e.g. occuring in ripe tomatoes) and is used as a food colouring. Cpd. (I) converts zeaxanthine-producing strains of Flavobacter (yellow colonies) into lycopene-producing nutants (red colonies).
