A note on the heterofermentative Lactobacillus isolated from kefir grains

M arshall , V.M., C ole , W.M. & F arrow , J.A.E. 1984. A note on the heterofermentative Lactobacillus isolated from kefir grains. Journal of Applied Bacteriology 56 , 503–505. Heterofermentative lactobacilli have been isolated from kefir grains obtained from four different sources. A number of these isolates ferment only L‐arabinose and gluconate and are similar to the species ‘Lactobacillus desidiosus’ . The DNA of these isolates, however, have 85–109% homology with ‘L. caucasicus’ NCDO 190 which is now regarded as L. kefir . The relationship between these strains is discussed.
