| Zusammenfassung: | <jats:p>A Gram-reaction-positive, non-motile actinobacterium, designated strain 210121<jats:sup>T</jats:sup>, was isolated from rhizosphere soil of the mangrove fern <jats:italic>Acrostichum speciosum</jats:italic>. 16S rRNA gene sequence analysis showed that the isolate belonged to the genus <jats:italic>Asanoa</jats:italic>. DNA–DNA relatedness values between strain 210121<jats:sup>T</jats:sup> and the type strains of the three recognized species of the genus <jats:italic>Asanoa</jats:italic> were below the 70 % threshold recommended for distinguishing bacterial genomic species. The novel isolate contained glutamic acid, glycine, alanine and <jats:italic>meso</jats:italic>-A<jats:sub>2</jats:sub>pm as cell-wall amino acids, indicating peptidoglycan type A1γ. The characteristic whole-cell sugars were xylose, ribose, glucose and mannose. The predominant menaquinones were MK-9(H<jats:sub>4</jats:sub>), MK-9(H<jats:sub>6</jats:sub>) and MK-9(H<jats:sub>8</jats:sub>). The major fatty acids were iso-C<jats:sub>16 : 0</jats:sub> (30.9 %), C<jats:sub>17 : 0</jats:sub> (23.0 %), anteiso-C<jats:sub>15 : 0</jats:sub> (14.9 %) and iso-C<jats:sub>15 : 0</jats:sub> (12.3 %). The phospholipid profile comprised phosphatidylethanolamine, phosphatidylinositol mannosides and phospholipids of unknown structure containing glucosamine. The G+C content of the DNA was 70.3 mol%. On the basis of the phenotypic and genotypic data, strain 210121<jats:sup>T</jats:sup> ( = CGMCC 4.5593<jats:sup>T</jats:sup> = DSM 45427<jats:sup>T</jats:sup>) represents a novel species of the genus <jats:italic>Asanoa</jats:italic>, for which the name <jats:italic>Asanoa hainanensis</jats:italic> sp. nov., is proposed. An emended description of the genus <jats:italic>Asanoa</jats:italic> is also proposed.</jats:p> |
