However, the increase in methionol production leveled off after 0.15%. The amount of methionol produced by yeast K. lactis KL71 in the medium with 0.25% L-methionine was not significantly higher than that of 0.15%, despite a 0.1% increase in L-methionine concentration. Thus, it would not be economically feasible to add up to 0.25% L-methionine to the coconut cream. 0.15% L-methionine concentration was used in subsequent fermentations for production of methionol
