Lactic acid bacteria count: fermented dairy, kimchi, and probiotic products

The basis for labelled viable counts

Illustrative image only. Actual product may vary.

THE SITUATION AND THE PAIN POINTS

Viable counts are central to labelling and QC of probiotic products and fermented foods. Results depend on the medium, incubation, and anaerobic conditions, and must be consistent batch to batch.

OUR APPROACH

MRS Agar (including the food-grade Halal version), M17 Agar, and Lactobacillus selective media, chosen by species and product; every batch verified with control strains.

  • MRS and M17 cover lactobacilli and lactococci
  • Food-grade Halal version usable directly in Halal product QC

Frequently asked questions

01Can bifidobacteria and lactobacilli be counted together?

Both grow on MRS and cannot be distinguished; use a dedicated selective medium when bifidobacteria must be counted separately.
