Lactobacillus helveticus

Lactobacillus helveticus [hel.ve’ti.cus. L. masc. adj. helveticus Swiss , referring to the isolation of the type strain from Emmental (Swiss) cheese].

Lactobacillus helveticus produces DL-lactic acid from glucose galactose, lactose, mannose and trehalose but not from cellobiose, mannitol, raffinose and sucrose. L. helveticus [ 2, 90] is an earlier heterotypic synonym of Lactobacillus suntoryeus [ 91]. The genome size of the type strain is 1.83 Mbp and the mol% G+C content of DNAis 36.8.

Part of the core microbiome of chicken [ 92] but it was also isolated from sour milk, cheese starter cultures and cheese, particularly Emmental and Gruyère cheeses, and in tomato pomace and silage.
