Genetic Analysis of Mating Type and Alkane Utilization in Saccharomycopsis lipolytica

Abstract
The mating reaction in Saccharomycopsis lipolytica is shown to be bipolar through the analysis of whole meiotic tetrads. Genetic evidence is provided that alkane metabolism proceeds through a fatty acid or a fatty acid intermediate since several mutants unable to grow on n-tetradecane were also unable to utilize palmitic acid.
