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 auxotrophy, implying that Y. lipolytica SCS2 has a different function from its Saccharomyces cerevisiae counterpart.
