Abstract
A hydrolyzate of molasses, containing both glucose and fructose, is mixed with calcium hydroxide, and a fructose addition precipitate is recovered. The residual liquor is neutralized, calcium ions are removed, and then the liquor is used as a carbon source for glutamic acid or lysine fermentation. The present method may supply very inexpensive fructose to the market.
Claims5
In the fermentation production of glutamic acid or lysine wherein fermentation is effected by the use of a microorganism of the genus Brevibacterium, Corynebacterium, Micrococcus or Microbacterium, the improvement which comprises:
- admixing a substantially neutral hydrolyzate of molasses containing glucose and fructose cooled to below 10.degree. C with calcium hydroxide to form a fructose addition product precipitate, and
- neutralizing the remaining mother liquor, simultaneously eliminating calcium ions therefrom, and utilizing the remaining liquor as the carbon source for said fermentation.
