Concerning L78M4, it did not outperform the original L78 strain
in either fermentation kinetics (data not shown) or wine compo-sition (Table 1). The time to reach a sugar concentration of 20 g/L for
L78 and L787M4 was 16 and 17 days respectively for must with
210 mg/L YAN, and 8 and 9 days respectively for 295 mg/L YAN.
Indeed, fermentation with this evolved strain resulted in lower
glycerol and higher acetic acid production than wines fermented
with the original one.
