sp. nov., isolated from the gut of plastic-eating insect larvae No Access

Abstract

A Gram-negative, non-motile and rod-shaped strain, BIT-DXN8, was isolated from the gut of plastic-eating insect larvae . The taxonomic position of this new isolate was examined by using a polyphasic approach. A preliminary analysis based on the 16S rRNA gene sequence (1411 bp) indicated that the most similar strain to BIT-DXN8 was DSM 14964 (98.5%), followed by CIP 64.3 (98.2%) and S23 (98.2%). The results of phylogenetic analyses, based on the 16S rRNA gene, concatenated sequences of five housekeeping genes (, , , and ) and genome sequences, placed strain BIT-DXN8 in a separate lineage among the genus of the family . The average nucleotide identity and digital DNA–DNA hybridization values of the strain when compared to all other species within the genus were below 96 and 70 %, respectively. The physiological and biochemical tests confirm the affiliation of strain BIT-DXN8 to the present species within the genus , but with some specific phenotypic differences. Therefore, strain BIT-DXN8 is considered to represent a novel species, for which the name sp. nov. is proposed. The type strain is BIT-DXN8 (=CCTCC AB 2022117=KCTC 92696).
