Pichia anomala

Pichia anomala is a species of ascomycete and teleomorphic fungi of the genus Pichia.[1] 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,[1] airtight stored grain (preventing Aspergillus flavus aflatoxins), apples, and grapevines.[2] P. anomala has been reclassified as Wickerhamomyces anomalus.[3]

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, , and .
  • glycerol, arabinitol, and trehalose under osmotic stress and oxygen limitation.
