Abstract
After training for 1, 2-propanediol, a yeast, Lipomyces starkeyi, grew well in the media containing the diol, showing a diauxie-like pattern. The yeast phospholipid was converted into monoacetyl-diglyceride by acetolysis. The presence of monoacetyl-mono fatty acyl esters of the diol in this fraction was found by GC-MS. The data suggested that the diol was present as 2-palmitoyl-ester and 2-oleoyl-ester in the form of phospholipid analogue, in which phosphorus bound in 1-position of the diol. Molecular species of the phospholipid was also deduced from the GC-MS data. Diol diester was not found in the triglyceride fraction of the yeast.
