A Gram-negative, coccoid-shaped bacterium, strain CC-CCM15-8T, was isolated from a rhizosphere soil sample of the plant Crossostephium chinense (L.) Makino (Seremban) from Budai Township, Chiayi County, Taiwan. 16S rRNA gene sequence analysis clearly allocated strain CC-CCM15-8T to the Paracoccus cluster, showing highest similarities to the type strains of ‘Paracoccus beibuensis’ (98.8 %), Paracoccus homiensis (97.6 %), Paracoccus aestuarii (97.7 %) and Paracoccus zeaxanthinifaciens (97.7 %). The fatty acid profile, comprising C18 : 1ω7c as the major component and C10 : 0 3-OH as the characteristic hydroxylated fatty acid, supported the placement of strain CC-CCM15-8T within the genus Paracoccus . The polyamine pattern consisted of putrescine and spermidine as major components. Ubiqinone Q-10 was the major quinone type (95 %); ubiquinone Q-9 was also detected (5 %). The complex polar lipid profile consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol, phosphatidylcholine, and unidentified phospholipids, lipids and glycolipids. Levels of DNA–DNA relatedness between strain CC-CCM15-8T and ‘P. beibuensis’ LMG 25871T, P. aestuarii DSM 19484T, P. zeaxanthinifaciens LMG 21993T and P. homiensis KACC 11518T were 24.9 % (34.8 %, reciprocal analysis), 15.7 % (17.5 %), 17.7 % (23.4 %) and 16.0 % (25.4 %), respectively. Physiological and biochemical test results allowed the phenotypic differentiation of strain CC-CCM15-8T from its closest relatives in the genus Paracoccus . Based on the data presented, it is concluded that strain CC-CCM15-8T represents a novel species of the genus Paracoccus , for which the name Paracoccus rhizosphaerae sp. nov. is proposed.

Diamino Acid

A Gram-positive, non-spore-forming bacterium (GW-12028T) of unknown origin showing filamentous growth and producing spherical sporangia was studied for its taxonomic allocation. The 16S rRNA gene sequence analysis and subsequent similarity studies showed that strain GW-12028T belongs to the genus Streptosporangium , and is most closely related to Streptosporangium pseudovulgare DSM 43181T (99.9 %) and Streptosporangium nondiastaticum DSM 43848T (99.6 %) and more distantly related to Streptosporangium fragile IFO 14311T (98.4 %) and other species of the genus Streptosporangium (95.8 to 98 %). Chemotaxonomic analyses showed that the peptidoglycan diamino acid was meso-diaminopimelic acid. Whole-cell hydrolysates contained madurose as the diagnostic sugar and exhibited a quinone system that contained predominantly menaquinones with nine isoprenoic units in the side chain [MK-9, MK-9(H2), MK-9(H4)]. The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylglycerol, phoshatidylethanolamine, hydroxyphosphatidylethanolamine, phosphatidylinositol, phosphatidylinositol-mannosides, four unidentified glycolipids, a phospholipid and an aminolipid. The polyamine pattern contained the major compounds spermine and spermidine. The major fatty acids were 10-methyl C17 : 0, iso-C16 : 0 and C15 : 0. These chemotaxonomic traits are common to other species of the genus Streptosporangium . DNA–DNA hybridizations and physiological and biochemical tests in comparison with the type strains of the most closely related species, S. nondiastaticum and S. pseudovulgare , allowed genotypic and phenotypic differentiation of strain GW-12028T. This strain represents a novel species, for which we propose the name Streptosporangium sandarakinum sp. nov., with the type strain GW-12028T ( = LMG 27062T  = DSM 45763T).
