Lactobacillus, the widest and most heterogeneous genus among lactic acid bacteria (LAB), comprises both homo- and heterofermentative species. Obligated heterofermentative lactobacilli (OHeL) produce CO2 from hexoses and may be present in raw milk as non-starter lactic acid bacteria (NSLAB). As all lactic acid bacteria possess GRAS status (Generally Recognized As Safe). Their presence in silage and in sourdough has also been reported. In a previous work 16 representative strains of a bigger group of OHeL-NSLAB, which were isolated from the environment and diverse products of several dairies, were genetically identified. Their study is interesting due to the possibility of identifying potential technological applications for those strains and of diversifying the industrial use of LAB.
