The phylogenetic analysis of 16S rRNA gene showed that the two strains belong to the genus Mucilaginibacter . Strain ZB1P21T showed the highest similarity to Mucilaginibacter rigui WPCB133T (97.35 %), while strain ZT4R22T showed the highest similarity to Mucilaginibacter gilvus F01003T (99.11 %). The average nucleotide identity values between the two novel strains and their closest relatives were 79.42 and 85.72 % respectively. The two novel strains contained MK-7 as the major menaquinone, and summed feature 3 (comprising C16 : 1  ω7c and/or C16 : 1  ω6c), iso-C15:0, iso-C17 : 03-OH and C16 : 1  ω5c as the major fatty acids. The major polar lipid of the two novel strains were phosphatidylethanolamine. Based on these data, we propose two novel species, Mucilaginibacter glaciei sp. nov. (ZB1P21T=CGMCC 1.23981T=NBRC 113932T) and Mucilaginibacter pankratovii sp. nov. (ZT4R22T=CGMCC 1.23487T=NBRC 113931T). %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijsem.0.004585
