Quality Assurance
Therabiotics provides Certificates of Analysis for all lots of Theralac®.
Probiotic Plate Counts
The Lactobacillus strains are reported as “Total Lactobacillus” and the Bifidobacterium strains as “Total Bifidobacterium.” These counts are reported in colony forming units (CFU)/gram on MRS agar (incubated at 37C for 72 hours). The “Total Lactobacillus” count is obtained by incubating the plates under aerobic conditions and counting all colonies; the “Total Bifidobacterium” count is obtained by incubating the plates anaerobically and then subtracting the Lactobacillus count from the total anaerobic count. This results in an approximation of the ratio of Lactobacilli to Bifidobacteria but is quite accurate with respect to the total probiotic count (Lactobacillus + Bifidobacteria).
