Based on sequence analysis of 16S rRNA genes, DNA G+C content (67·4–69·2 mol%), quinone type (UQ-8), major fatty acid composition (3-OH 10 : 0, 3-OH 14 : 0) and other phylogenetic studies, strains 3001T, 12 and 13 were found to occupy a separate position in the ‘Betaproteobacteria’. Roseateles depolymerans, Rubrivivax gelatinosus and Ideonella dechloratans were their closest neighbours (93–95 % 16S rRNA gene sequence similarity). The 16S rRNA gene sequence and other characteristics suggested that strain 2 belonged to the genus Flavobacterium. DNA–DNA hybridization experiments supported the conclusion that strains 3001T, 12 and 13 were of the same species (72–78 % DNA hybridization) and only distantly related to I. dechloratans and R. gelatinosus. It is proposed that strains 3001T, 12 and 13 represent a novel genus and species for which the name Mitsuaria chitosanitabida gen. nov., sp. nov. is proposed. The type strain of Mitsuaria chitosanitabida is 3001T (=IAM 14711T=ATCC BAA-476T). %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.63629-0
