Upon initial consideration the lack of difference between the viability of L. acidophilus La-05 assayed in either MRS broth or goat ricotta could be considered unimportant. However these results are interesting because when this probiotic strain was incorporated into a goat semi-hard cheese the survival rate decreased within 72 min of exposure to gastric juice (pH of 2.3; 6th digestion step; esophagus–stomach condition) (Oliveira et al., 2014).
