Differential phenotypic characteristics of the novel isolates and related species of the genus Taxa: 1, strain C15; 2, strain C44; 3, LMG 6083; 4, S2R03-9; 5, DSM 19779; 6, DSM 18207; 7, DSM 5686; 8, JT1. +, Positive; −, negative; (+), weak; , variable results. Data were obtained comparatively in this study. Results in brackets are from: 3, ); 4, ; 5, ; 6, ; 7, ; 8, . All strains were positive for hydrolysis of bis--nitrophenyl (bis-pNP) phosphate* and -alanine -nitroanilide (pNA)*† and negative for hydrolysis of pNP β--xylopyranoside*. All strains were negative for acid production from -trehalose* and assimilation of maltitol*, -mannitol* and -leucine*.
