Pichia anomala is a species of ascomycete and teleomorphic fungi of the genus Pichia.[1] It is notably used as a competitive preventative (biocontrol agent) for undesirable fungi/mold, nevertheless it may spoil foodstuffs in large enough quantities. It is used in winemaking,[1] airtight stored grain (preventing Aspergillus flavus aflatoxins), apples, and grapevines.[2]
Features
Distinguished from some other species of Pichia by high osmotolerance, P. anomala ferments sucrose, and assimilates raffinose.[1] Does not exhibit crabtree effect but rather Pasteur effect.
Products
- 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.
