Xanthophyllomyces dendrorhous ATCC 74221/UBV-AX4
(formerly Phaffia rhodozyma) is a red-pigmented
basidiomycete yeast. This strain is the result of multiple rounds
of chemical mutagenesis and selection for astaxanthin
overproduction, producing 4.67 g astaxanthin / g dry yeast solid in
a 14 L fermenter (Jacobson, 1995).
This strain was obtained from the ATCC,
and was deposited by Universal Foods Corporation.
The Xanthophyllomyces dendrorhous UBV-AX4 genome was not sequenced by the JGI. The assembly was provided by Eric Young and it was annotated using the JGI Fungal Annotation Pipeline.
