The bacterial population of a commercial freeze-dried mixed-strain starter culture was 63 % Lactococcus lactis ssp. cremoris and 37 % Lactococcus lactis ssp. lactis biovar. diacetylactis. No strains of Lactococcus lactis ssp. lactis and Leuconostoc mesenteroides ssp. cremoris were detected. These strains were divided into 16 groups of L. lactis ssp. cremoris and four groups of L. lactis ssp. lactis biovar. diacetylactis. Four phages were isolated from the starter culture. Three attacked L. lactis ssp. cremoris strains, and one attacked L. lactis ssp. lactis biovar. diacetylactis. Although 32 % of isolates were lysogenic, no indicator strains were detected. Twelve strains of L. lactis ssp. cremoris isolates had fast milk-coagulating ability, and two of those showed high acid-producing activity.
