The coenzyme Q productivity of Candida tropicalis pK 233 was compared using various carbon sources. The compounds used as sole carbon sources included carbohydrates, acids in the TCA cycle, short chain alcohols, diols and fatty acids, n-alkanes, n-alkenes and n-alkane mixtures. Among the compounds examined, n-alkanes were the best carbon sources for coenzyme Q production. From ethanol used as the sole carbon source, this yeast produced as much coenzyme Q as from n-alkanes. Carbohydrates were inferior to n-alkanes as carbon sources for coenzyme Q production. This yeast was unable to assimilate the TCA cycle acids and most of the short chain alcohols, diols, and fatty acids as sole carbon sources. Among the n-alkanes tested, n-decane, n-undecane and n-dodecane were found to be the best substrates for coenzyme Q production by this yeast. In accordance with this result, an n-alkane mixture of n-decane, n-undecane and n-dodecane (designated as"hydrocarbon mixture 4") was also a better carbon source for coenzyme Q production than mixtures of longer chain n-alkanes. Among the non-ionic detergents tested Tween 80 was most conclusive to coenzyme Q production. Tween 85 was most stimulatory to the growth of this yeast.
