NOTES: Leuconostoc mesenteroides subsp. cremoris (Knudsen and Sorensen) comb. nov. and Leuconostoc mesenteroides subsp. dextranicum (Beijerinck) comb. nov.

Abstract

Leuconostoc mesenteroides (Tsenkovskii) van Tieghem 1878, Leuconostoc dextranicum (Beijerinck) Hucker and Pederson 1930, and Leuconostoc cremoris (Knudsen and Sørensen) Garvie 1960 belong to a single deoxyribonucleic acid homology group. These three organisms have similar lactate dehydrogenases and glucose-6-phosphate dehydrogenases. Because of these common properties, these organisms are here regarded as subspecies within a single species, Leuconostoc mesenteroides. The names of the subspecies are Leuconostoc mesenteroides subsp. mesenteroides, Leuconostoc mesenteroides subsp. dextranicum (Beijerinck) comb. nov., and Leuconostoc mesenteroides subsp. cremoris (Knudsen and Sørensen) comb. nov. The type strains of these subspecies are ATCC 8293, NCDO 529, and NCDO 543, respectively.
