3.1.3. Lipolytic Activities. Lipolytic activities were recognized by the presence of a clear halo in the tributyrin agar plates.
Out of the 174 strains of L. fermentum screened for lipolytic activities, 32% were negative (showed no clear zones on the
agar plates). Similarly, L. plantarum and L. helveticus had 9% and 8.6% strains not showing lipolytic activities, respectively
(Table 2). Generally, majority of the strains tested for lipolysis were positive.
