| Zusammenfassung: | <jats:p>Strain 211020<jats:sup>T</jats:sup> was isolated from rhizosphere soil of <jats:italic>Excoecaria agallocha</jats:italic> in a mangrove in Hainan, China. The strain produced longitudinal pair spores branching from aerial hyphae. 16S rRNA gene sequence analysis showed that the isolate belonged to the genus <jats:named-content xmlns:xlink="http://www.w3.org/1999/xlink" content-type="genus" xlink:type="simple"> <jats:ext-link ext-link-type="uri" xlink:href="http://dx.doi.org/10.1601/nm.7454" xlink:type="simple"> <jats:italic>Microbispora</jats:italic> </jats:ext-link> </jats:named-content>, exhibiting the highest 16S rRNA gene sequence similarity (98.75 %) to <jats:named-content xmlns:xlink="http://www.w3.org/1999/xlink" content-type="species" xlink:type="simple"> <jats:ext-link ext-link-type="uri" xlink:href="http://dx.doi.org/10.1601/nm.7461" xlink:type="simple"> <jats:italic>Microbispora corallina</jats:italic> </jats:ext-link> </jats:named-content> JCM 10267<jats:sup>T</jats:sup> with a low DNA–DNA relatedness value (13±0.6 %). The isolate contained <jats:italic>meso</jats:italic>-diaminopimelic acid as the diagnostic diamino acid but madurose was not detected. The predominant menaquinones were MK-9(H<jats:sub>4</jats:sub>), MK-9(H<jats:sub>2</jats:sub>) and MK-9(H<jats:sub>0</jats:sub>), and the major fatty acids were iso-C<jats:sub>16 : 0</jats:sub>, iso-C<jats:sub>15 : 0</jats:sub> and C<jats:sub>17 : 0</jats:sub>. The phospholipid profile of strain 211020<jats:sup>T</jats:sup> comprised phosphatidylinositol mannoside, phosphatidylethanolamine, diphosphatidylglycerol and phospholipids of unknown structure containing glucosamine. The DNA G+C content was 70.8 mol%. On the basis of phenotypic and genotypic data, strain 211020<jats:sup>T</jats:sup> can be distinguished as a novel species of the genus <jats:named-content xmlns:xlink="http://www.w3.org/1999/xlink" content-type="genus" xlink:type="simple"> <jats:ext-link ext-link-type="uri" xlink:href="http://dx.doi.org/10.1601/nm.7454" xlink:type="simple"> <jats:italic>Microbispora</jats:italic> </jats:ext-link> </jats:named-content>, for which the name <jats:italic>Microbispora hainanensis</jats:italic> sp. nov., is proposed. The type strain is 211020<jats:sup>T</jats:sup> ( = CGMCC 4.5595<jats:sup>T</jats:sup> = DSM 45428<jats:sup>T</jats:sup>).</jats:p> |
