Micromonospora soli sp. nov., isolated from rice rhizosphere soil

Abstract

An actinomycete strain SL3-70T was isolated from a rice field and characterised using a polyphasic approach. The morphological and chemotaxonomical characteristics of strain SL3-70T indicate that it belongs to the genus Micromonospora. The phylogenetic analysis of the nearly complete 16S rRNA gene sequence revealed that strain SL3-70T is a member of the genus Micromonospora, and is closely related to Micromonospora echinaurantica DSM 43904T (99.1 % 16S rRNA gene sequence similarity) and Micromonospora kangleipakensis MBRL 34T (98.8 %). DNA–DNA relatedness between strain SL3-70T and its relatives ranged from 21.2 % ± 0.6 to 38.7 % ± 0.4. The results obtained from our study indicate that strain SL3-70T represents a novel species of the genus Micromonospora, for which the name Micromonospora soli sp. nov. is proposed. The type strain is SL3-70T (=BCC 67268T; =NBRC 110009T).
