Wickerhamomyces anomalus is a species of ascomycete and teleomorphic fungi of the genus Wickerhamomyces.[2] It is used as a preventive (biocontrol agent) for undesirable fungi or mold, nevertheless it may spoil food in large quantities. It is used in wine making,[2] airtight stored grain (preventing Aspergillus flavus aflatoxins), apples, and grapevines.[3] P. anomala has been reclassified as Wickerhamomyces anomalus.[4]

Features
editDistinguished from some other species of Pichia by high osmotolerance, P. anomala ferments sucrose, and assimilates raffinose.[2] Does not exhibit crabtree effect but rather Pasteur effect.
Products
edit- ethanol under anaerobiosis
- acetate under respiratory and respirofermentative growth.
- ethyl acetate from glucose under oxygen limitation, also other small volatiles, e.g., ethyl propanoate, phenyl ethanol, and 2-phenylethyl acetate.
- glycerol, arabinitol, and trehalose under osmotic stress and oxygen limitation.
