Lactobacillus delbrueckii subsp. bulgaricus Weiss et al. 1984

Description

Lactobacillus delbrueckii subsp. bulgaricus

Lactobacillus delbrueckii subsp. bulgaricus (bul.ga’ri.cus. N.L. masc. adj. bulgaricus, Bulgarian).

Strains of this subspecies were previously referred to as L. bulgaricus. L. delbrueckii subsp. bulgaricus ferment glucose to D(−)-lactic acid and also metabolise fructose, mannose and lactose, but not sucrose [60, 61]. L. delbrueckii subsp. bulgaricus undergoes genome reduction which particularly relates to loss or silencing of genes coding for metabolism of carbohydrates [57]. The genome size is 1.76 Mbp and the G+C content of DNA is 49.9 mol%.

Isolated from yoghurt and cheese and an important starter cultures in the production of these foods [58, 59] but also detected by culture-independent methodology in the intestinal microbiota of suckling piglets [54].

The type strain is ATCC 11842 T = CCUG 41390 T = CIP 101027 T = DSM 20081 T = IFO (now NBRC) 13953 T = JCM 1002 T = LMG 6901 T = LMG 13551 T = NCTC 12712 T = VKM B-1923 T.

Genome sequence accession number: JQAV00000000.

16S rRNA gene accession number: CR954253.
