They are then outgrown by more acid-tolerant species including Lactobacillus casei (1.5– 2.0% acid) and Lactobacillus bulgaricus (2.5–3.0% acid). Similarly, in vegetable fermentations, Lactobacilli spp. are stronger acid producers than Streptococci spp. Of the four main groups of lactic acid bacteria, Streptococcus spp. and Pediococcus spp. are homolactic,
Leuconostoc spp. are heterolactic and Lactobacillus spp. vary according to the strain. In some fermentations, particularly those that involve low-acid substrates (for example milk and meat), a starter culture is added to rapidly generate large numbers of the desired
