Based on 16S rRNA gene phylogeny, the novel strains represent three new branches within the genus Mucilaginibacter. The strains were aerobic, chemo-organotrophic, non-motile rods and formed pigmented, smooth, mucoid colonies on solid media. The strains grew between 0 and 33 °C (optimum growth at 25 °C) and at pH 4.5–8.0 (optimum growth at pH 6.0). The main cellular fatty acids were iso-C15 : 0, summed feature 3 (C16 : 1 ω7c/iso-C15 : 0 2-OH) and iso-C17 : 0 3-OH and the major respiratory quinone was MK-7. The DNA G+C contents were 44.0–46.5 mol%. Based on phylogenetic, phenotypic and chemotaxonomic data, the strains represent three novel species of the genus Mucilaginibacter for which the names Mucilaginibacter frigoritolerans sp. nov. (type strain FT22T =ATCC BAA-1854T =LMG 25359T), Mucilaginibacter lappiensis sp. nov. (type strain ANJLI2T =ATCC BAA-1855T =LMG 25358T) and Mucilaginibacter mallensis sp. nov. (type strain MP1X4T =ATCC BAA-1856T =LMG 25360T) are proposed. %U https://www.microbiologyresearch.org/content/journal/ijsem/10.1099/ijs.0.019364-0
