he quantitative analytical method for Lactic Acid Bacteria (LAB) in Korea Food Standard was reviewed in caseof measurement for some market yoghurts. Contents of LAB in fermented yoghurt in Korea food market were investigated.BCP plate count agar, PCA with BCP, and MRS were tested for the measurement of LAB. The measured count for LAB inthe product were determined as following order; BCP plate count agar > MRS agar > PCA with BCP. The measured LABrange in the product using BCP plate count agar was between 116×107 and 180×107 CFU/mL, that using MRS agar wasbetween 18.6×107 and 23.2×107 CFU/mL, and that using PCA with BCP was 3×105 and 22×105 CFU/mL. As the results,use of proper medium for the accurate LAB measurement including coccus as well as bacillus would be recommended.
