The viability of Lactobacillus paracasei and its effect on growth of the microbiota in potentially probiotic and synbiotic fresh cheeses during storage at 4 +/- 1 degree C was investigated. Three cheese-making trials (T1, T2, and T3) were prepared in quadruplicate, all supplemented with a Streptococcus thermophilus culture. L. paracasei subsp. paracasei was added to cheeses in T1 and T2, and inulin was added to cheeses in T2. Counts of L. paracasei, S. thermophilus, coliforms, Escherichia coli, Staphylococcus spp., DNase-positive Staphylococcus, and yeasts and molds were monitored during storage for up to 21 days. Viable counts of L. paracasei in probiotic (T1) and synbiotic (T2) cheeses remained above 7 log CFU/g during the entire storage period, whereas counts of S. thermophilus remained above 9.5 log CFU/g for cheeses from TI, T2, and T3. Populations of coliforms, Staphylococcus spp., and DNase-positive Staphylococcus were higher in T3 cheese and differed significantly from those in cheeses from T1 and T2 (P < 0.05). Inhibition of contaminants prevailed when both L. paracasei and S. thermophilus were present in fresh cream cheese and probably was due to acid production by both strains; bacteriocin production was not found. Addition of inulin in T2 did not impact microbial viability (P > 0.05). L. paracasei subsp. paracasei in coculture with S. thermophilus was inhibitory against microbial contaminants in fresh cream cheese with or without the addition of inulin, indicating the potential use of this combination in a probiotic and synbiotic product.
