Fig. 2

Metabolic pathways of Lactobacillus fermentum 222 and Lactobacillus plantarum 80. The names of the genes that were present in both genomes are depicted in blue, those that were present in L. fermentum 222 only are depicted in yellow, and those that were present in L. plantarum 80 only are depicted in grey. Metabolites involved in the homo- and heterolactic fermentation pathways are depicted in green, those involved in pyruvate metabolism are depicted in purple, those involved in citrate metabolism are depicted in black, those involved in the proteolytic system and amino acid conversion pathways are depicted in orange, those involved in the arginine deiminase pathway are depicted in red, and those involved in the respiratory machinery are depicted in dark red. Enzymes and locus tags that were associated with the gene names are listed in Additional file 3.
