Abstract
Several classes of water immiscible lipophilic phases effect the transfer of crystalline orange precursor pigments produced by Monascus species in an aqueous culture medium from the aqueous to the lipophilic phase without solubilizing a major portion of the pigment. Liquid vegetable and mineral oils are two such classes. This phenomenon permits high recovery of pigment in a simple and convenient manner, and also permits development of a batch recycle and a continuous fermentation process for pigment production.
