Description of Jidongwangia harbinensis gen. nov. sp. nov.

ABSTRACT

During our previous study, strain NEAU-J3T was classified as representing a novel genus 'Wangella' within the family Micromonosporaceae. Nevertheless, it is a great pity the name cannot be validated as the proposed genus name is illegitimate (Principle 2 of the ICNP). In this study, we describe Jidongwangia as a novel genus within the family Micromonosporaceae and a polyphasic approach was used to provide evidence to support the classification. The G+C content of the genomic DNA of the type strain is 71.6 %. Digital DNA-DNA hybridization and average nucleotide identity (ANI) values could be used to differentiate NEAU-J3T from its related type strains. The phenotypic, genetic and chemotaxonomic data also indicated that NEAU-J3T occupies a branch separated from those of known genera in the family Micromonosporaceae. Therefore, NEAU-J3T represents a novel species of a novel genus in the family Micromonosporaceae, for which the name Jidongwangia harbinensis gen. nov., sp. nov. is proposed. The type strain of Jidongwangia harbinensis is NEAU-J3T (= CGMCC 4.7039T = DSM 45747T).
