Wickerhamomyces anomalus is a species of ascomycete and teleomorphic fungi of the genus Wickerhamomyces. 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, airtight stored grain (preventing Aspergillus flavus aflatoxins), apples, and grapevines.{{cite journal|url=http://aem.asm.org/content/70/10/5905.full|title=Oxygen- and Glucose-Dependent Regulation of Central Carbon Metabolism in Pichia anomala|date=2004 |publisher=aem.asm.org|doi=10.1128/AEM.70.10.5905-5911.2004 |accessdate=2016-04-16 |last1=Fredlund |first1=Elisabeth |last2=Blank |first2=Lars M. |last3=SchnüRer |first3=Johan |last4=Sauer |first4=Uwe |last5=Passoth |first5=Volkmar |journal=Applied and Environmental Microbiology |volume=70 |issue=10 |pages=5905–5911 |pmid=15466531 |pmc=522099 |bibcode=2004ApEnM..70.5905F }} P. anomala has been reclassified as Wickerhamomyces anomalus.{{Cite journal|last1=Madrigal|first1=T.|last2=Maicas|first2=S.|last3=Mateo Tolosa|first3=J.

Features

Distinguished from some other species of Pichia by high osmotolerance, P. anomala ferments sucrose, and assimilates raffinose.{{cite web|url=http://wineserver.ucdavis.edu/industry/enology/winemicro/wineyeast/pichia_anomala.html|title=Pichia anomala | Viticulture & Enology|publisher=wineserver.ucdavis.edu|accessdate=2016-04-16}} Does not exhibit crabtree effect but rather Pasteur effect.
