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.
