A bacterial strain, designated IMCC1731T, was isolated from an eutrophic freshwater pond and characterized using a polyphasic taxonomic approach. Cellular growth occurred at pH 6-9 (optimum, pH 8.0), at 10-30 °C (optimum, 25 °C) and with 0-1 % (w/v) NaCl (optimum, 0 %). Phylogenetic analyses based on 16S rRNA gene sequences indicated that strain IMCC1731T belonged to the genus Emticicia in the family Cytophagaceae and was most closely related to Emticicia ginsengisoli Gsoil 085T (98.1 %) followed by Emticicia paludis HMF3850T (95.0 %), Emticicia oligotrophica DSM 17448T (94.7 %), Emticicia aquatica HMF2925T (94.4 %) and Emticicia sediminis JBR12T (94.0 %). The DNA-DNA relatedness between strain IMCC1731T and E. ginsengisoli Gsoil 085T was 47±4 %. The DNA G+C content of strain IMCC1731T was 37.7 mol%. The predominant cellular fatty acids were summed feature 3 (C16 : 1ω6c and/or C16 : 1ω7c) and iso-C15 : 0. Based on the physiological and chemotaxonomic characteristics, DNA-DNA relatedness and 16S rRNA gene phylogeny, stain IMCC1731T is considered to represent a novel species of the genus Emticicia, for which the name Emticicia fontis sp. nov. is proposed. The type strain is IMCC1731T (=KCTC 52248T=JCM 31373T).

Article Synopsis
- A new bacterial strain, designated 17J42-9, was isolated from soil on Jeju Island and is identified as Gram-negative and rod-shaped with orange colonies on R2A agar.
- Genetic analysis revealed that it is closely related to other strains with over 98% 16S rRNA sequence similarity, but DNA-DNA hybridization showed low relatedness, indicating it is a unique species.
- Further biochemical and genetic studies supported the classification of strain 17J42-9 as a novel species, proposed to be named sp. nov., with the type strain being 17J42-9 (=KCTC 62270=JCM 33056).

Bacterial strain ZZ-4T, a Gram-stain-negative, aerobic, non-spore-forming, non-motile, non-flagellated, rod-shaped bacterium, was isolated from tetrabromobisphenol A-contaminated soil in PR China. The taxonomic position of this strain was investigated using a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain ZZ-4T was a member of the genus Emticicia and showed the highest sequence similarity to Emticicia fontis IMCC1731T (98.
