The draft genome sequence of Meyerozyma guilliermondii strain YLG18, a yeast capable of producing and tolerating high concentration of 2-phenylethanol

The draft genome of a wild-type Meyerozyma guilliermondii strain YLG18, which could convert l-phenylalanine (l-phe) to 2-phenylethanol (2-PE) and tolerate high concentration of 2-PE was sequenced and analyzed. 18S rDNA analysis indicated that strain YLG18 is closely related to M. guilliermondii. The assembled draft genome of strain YLG18 is 12.8 Mb, containing 5275 encoded protein sequences with G + C content of 43.75%. Among these annotated genes, two aminotransferases, one phenylpyruvate decarboxylase and two bifunctional alcohol dehydrogenases (adh) play key roles in the achievement of 2-PE production from l-phe via Ehrlich pathway. In addition, membrane protein insertase (YidC), heat shock protein (Hsp90) and chaperons (SGT1) were identified, which may contribute to the increased tolerance to 2-PE.
