Abstract
The present invention relates to a process for preparing a nutritional, therapeutic or organoleptic product by growing non-recombinant yeast under aerobic conditions, in a medium that includes crude glycerol, as one possible carbon source to produce a yeast product. The yeast product can be processed to obtain such nutritional, therapeutic or organoleptic products as yeast paste, yeast metabolites, carbohydrates, proteins, functional proteins, nucleotides, yeast autolysates, yeast extract, yeast cell walls, beta-glucans, mannans or a product derived from a mineralized yeast product.
Claims23
A process for preparing a nutritional, therapeutic or organoleptic product comprising:
- (a) growing non-recombinant yeast, under aerobic conditions, in the presence of a medium comprising one or more carbon sources, one of which is crude glycerol containing approximately from 15% to approximately 95% wt/wt glycerol and the concentration of glycerol in the medium is approximately from 50.0 to approximately 500.0 g/L, and one or more sources of nitrogen to produce a yeast product;
- wherein the carbon to nitrogen ratio of the medium is less 90:1;
- and
- (b) processing the yeast product to obtain the nutritional, therapeutic or organoleptic product,
- wherein the growth of the yeast exhibits a process productivity rate of greater than or equal to 0.85 gram of yeast biomass on a dry basis per liter of medium per hour (g.L−1.h−1).
