These strains showed the ability to degrade biodegradable plastics, poly(butylene succinate--adipate) (PBSA) and poly(-caprolactone). Phylogenetic analyses based on the 16S rRNA gene sequences revealed that strains 4NK60-0013 and 4NH20-0068 belong to the family in the order and are closely related to members of the genus . The species most closely related to strains 4NK60-0013 and 4NH20-0068 were M5c and YN3, with 16S rRNA gene sequence similarities of 94.4 and 93.3%, respectively. The sequence similarity between the two novel strains was 94.8%, indicating that they represented separate species. The genome length and G+C content of the genome sequence of strain 4NK60-0013 were 4,354,061 bp and 46.9 mol%, respectively, whereas those of strain 4NH20-0068 were 4,154,637 bp and 43.3 mol%, respectively. The average nucleotide identity values between the strains were
