¹C-sources that gave a positive reaction in at least one strain but not all the strains are shown. Symbols: -, negative reaction; +, positive reaction. Opm generated results showing phenotypic variability on different C-sources among the isolates: (i) Lm3163 utilizes the most C-sources. (ii) Strains demonstrate lineage associated ability to utilize β-D-allose.
