Micromonospora craniellae sp. nov., isolated from a marine sponge, and reclassification of Jishengella endophytica as Micromonospora endophytica comb. nov. Li, Lei and Zhu, Hong-rui and Xu, Qi-hang and Lin, Hou-wen and Lu, Yan-hua,, 69, 715-720 (2019), doi = https://doi.org/10.1099/ijsem.0.003209, publicationName = Microbiology Society, issn = 1466-5026, abstract= A novel marine actinomycete, designated LHW63014T, isolated from a marine sponge, Craniella species, collected in the South China Sea, was examined using a polyphasic approach. The 16S rRNA gene sequence of strain LHW63014T showed highest similarities to Jishengella endophytica 202201T (98.9 %), Micromonospora olivasterospora DSM 43868T (98.7 %), Micromonospora maris AB-18-032T (98.6 %) and Micromonospora gifhornensis DSM 44337T (98.6 %). Phylogenetic analyses of the family Micromonosporaceae based on the 16S rRNA and gyrB gene sequences indicated that strain LHW63014T and J. endophytica 202201T located within the genus Micromonospora . Morphological and chemotaxonomic characteristics confirmed their affiliation to the genus Micromonospora . Based on phenotypic characteristics, phylogenetic data and digital DNA–DNA hybridization results, strain LHW63014T could be distinguished from its closest taxa, representing a novel species of the genus Micromonospora , for which the name Micromonospora craniellae sp. nov., is proposed, with the type strain LHW63014T (=DSM 106193T=CCTCC AA 2018012T). It is also proposed that J. endophytica be transferred to genus Micromonospora as Micromonospora endophytica comb. nov. (type strain 202201T =CGMCC 4.5597T=DSM 45430T)., language=, type=
