Disruption of the SCS2 Ortholog in the Alkane-Assimilating Yeast Yarrowia lipolytica Impairs Its Growth on n-Decane, but Does Not Impair Inositol Prototrophy

Abstract

Disruption of an SCS2 ortholog impaired the growth of the alkane-assimilating yeast Yarrowia lipolytica on n-alkanes, particularly on n-decane, although the mRNA level of the ALK1 gene encoding a highly inducible cytochrome P450ALK was not much affected. The same disruption did not cause inositol auxotropy, implying that Y. lipolytica SCS2 has a different function from its Saccharomyces cerevisiae counterpart.
