Growth of Lactobacillus paracasei A13 in Argentinian probiotic cheese and its impact on the characteristics of the product.

The growth capacity of probiotic Lactobacillus paracasei A13, Bifidobacterium bifidum A1 and L. acidophilus A3 in a probiotic fresh cheese commercialized in Argentina since 1999 was studied during its manufacture and refrigerated storage at 5 degrees C and 12 degrees C for 60 days. Additionally, viable cell counts for probiotic bacteria in the commercial product are reported for batch productions over the last 9 years.

Viability of probiotic (Bifidobacterium, Lactobacillus acidophilus and Lactobacillus casei) and nonprobiotic microflora in Argentinian Fresco cheese.

We evaluated the suitability of Argentinian Fresco cheese as a food carrier of probiotic cultures. We used cultures of Bifidobacterium bifidum (two strains), Bifidobacterium longum (two strains), Bifidobacterium sp. (one strain), Lactobacillus acidophilus (two strains), and Lactobacillus casei (two strains) in different combinations, as probiotic adjuncts.
