The microbiology of South African traditional fermented milks

A total of 15 samples of traditional fermented milk were collected from individual households in South Africa and Namibia. Lactic acid bacteria dominated the microflora of these samples, especially the genera Leuconostoc, Lactococcus and Lactobacillus. Other groups identified included pyogenic streptococci and enterococci. The dominant lactococci species was Lactococcus lactis subsp. lactis. Eighty-three percent of the leuconostoc isolates were identified as Leuconostoc mesenteroides subsp. dextranicum. Other species identified included Leuconostoc citreum, Leuconostoc lactis, Lactobacillus delbrueckii subsp. lactis and Lactobacillus plantarum. (C) 2001 Elsevier Science B.V. All rights reserved.
