- Taxa 1, G. zalihae T1T; 2, G. Kaustophilus (DSM 7263T); 3, G. thermoleovorans (DSM 5366T). Characteristics are scored as: +, positive; -, negative; w, weak; v, variable within the group; ND, not determined. Data were obtained from the present study (G. zalihae strain T1T), Nazina et al. [16], Sunna et al. [3], Kuisiene et al. [14] and Markossian et al. [54] (G. thermoleovorans DSM 5366T and G. Kaustophilus DSM 7263T). All strains were negative for anaerobic growth, growth at 30°C, VP reaction, indole production and acid from L-rhamnose, sorbitol. All strains were positive for catalase, hydrolysis of starch, use of citrate and acid from D-fructose and D-glucose.
