From: Functional genomics of lactic acid bacteria: from food to health
A phylogenetic tree of based on sequences of 7 housekeeping genes ( rec A, rpo D, dna K, inf C, rpl A, rps B and rpm A) from the 36 LAB species. The tree was generated using previously described computational methods [210–219]. Species were colored according to their genus (purple, Leuconostoc spp. ; yellow, Lactobacillus spp. ; blue, Pediococcus spp.; green, Lactococcus spp.; pink, Streptococcus spp. ; orange, Enterococcus spp. ; grey, Oenococcus spp. ). In addition, the presence of isolates in a particular niche are indicated by colored dots (dark green, plant material; green, food products; orange, oral cavity; purple, gastro-intestinal tract; magenta, vaginal cavity and blue, other body sites and clinical isolates). This illustrates the ecological versatility of each species but does not further detail its ecological role, i.e. transient (allochthonous) or endogenous (autochthonous).
