Table 1. Summary table of comparisons for all species, including a subset of carbon usage types.
We show the specific strain names for the three Paraburkholderia sp. nov. and the reference Paraburkholderia strains, the number of Paraburkholderia sp. nov. isolates in each group with the type strain in bold, whether or not the isolates are associated with D. discoideum (positive association indicated by a + sign), average bacterial length, optimal growth temperature, and metabolic tests. Next, a subset of about one-fourth of the relevant carbon types follows. P. agricolaris and P. bonniea are able to utilize some carbons that their close Paraburkholderia relatives cannot. A plus (+) symbol indicates all isolates were able to use a specific carbon and a minus (−) symbol indicates that they could not use that carbon. A number value indicates the percentage of strains in a specific group that can utilize that particular carbon. Specifics for each individual strain can be found in the supplemental information (raw data files).
