Baeza Cancino, Marcelo; Retamales Molina, Patricio; Sepúlveda, Dionisia; Lodato, Patricia; Jiménez, Antonio; Cifuentes Guzmán, Víctor (WILEY-V C H VERLAG GMBH, 2008-05-16)The yeast Xanthophyllomyces dendrorhous is biotechnologically important due to its ability to produce the pigment astaxanthin, but is poorly understood at the genetic level. This is mainly because its preservation is ...
