Nevertheless, only two strains were found to be able to produce 3-methylbutanal or the reduced aldehyde, 3-methylbutanol. This 3-methylbutanal production clearly correlated with the presence or absence of decarboxylase activity. Again the difference between L. lactis B1157 and B697 is illustrative (Fig. 3), with B1157 being decarboxylase-positive and B697 negative.
