Abstract
Riboflavin is recovered from fermentation broth by diluting the broth with a predetermined quantity of water, centrifuging the diluted broth to form a sludge, resuspending the sludge with a predetermined quantity of water, and centrifuging the resuspended sludge to yield a product usuable directly as an animal feed supplement or suitable for further purification for pharmaceutical use. Optionally the broth or resuspended sludge is treated with an enzyme before centrifugation.
