“…For example, strain HAW-EB21 T did not grow on succinate, the carbon source for the isolation of members of the genus Propionigenium (Schink & Pfennig, 1982;Janssen & Liesack, 1995;Schink, 1992), or on L-tartrate, 3-hydroxybutyrate or quinate (and shikimate) which have been used for the isolation of Ilyobacter tartaricus (Schink, 1984), Ilyobacter polytropus (Stieb & Schink, 1984) and Ilyobacter insuetus (Brune & Schink, 1992;Brune et al, 2002), respectively. T different from the most closely related species of the genera Ilyobacter and Propionigenium Taxa: 1, strain HAW-EB21 T ; 2, I. tartaricus (data from Schink, 1984); 3, I. insuetus (Brune & Schink, 1992); 4, I. polytropus (Stieb & Schink, 1984); 5, Propionigenium modestum (Schink & Pfennig, 1982); 6, Propionigenium maris (Janssen & Liesack, 1995;Watson et al, 2000).…”
