+, growth; -, no growth; l, latent; s, positive but slow; v, variable; w, weak; u, uncertain. Data for the new species taken from the ex-type strains (S. clarorosea, WRP 7; S. pseudomarina, SA716; S. suhii, BG 02-5-27-3-2-2). Data for the reference species taken from Kurtzman et al. (2011).
a The assimilation of L-rhamnose was uncertain for the ex-type strain but positive for the other strain tested (SA42).
