Fermentative production of aroma and/or flavor materials from amino acid in bioreactor, comprises forming Saccharomyces/Kluyveromyces two phase system having aqueous growth medium with water, which is not miscible with polypropylene glycol

摘要

The glycol has a molecular weight of 1200-1800. The amino acid used is phenylalanine in a large quantity, which separates in the aqueous phase by bio converting reaction. Carbon source and vitamins for cell growth and minerals are added to the growth medium. The ratio of glycol is 1:1. The process further comprises separating the emulsion by constant agitating and centrifuging.
