Fermentative production of squalene under anaerobic conditions using commercially available compressed baker's yeast (Saccharomyces cerevisiae), and a strain of Torulaspora delbrueckii isolated from molasses was studied. Yield of squalene from S. cerevisiae and T. delbrueckii were found to be 41.16 and 237.25 mug g(-1) respectively, dry weight of yeast cells. Isolation and purification of squalene from the lipid extracts obtained by cell lysis of either strain were achieved chromatographically. The purified squalene was characterized spectroscopically against an authentic standard.
