Abstract (EN): A bacterial strain, designated FF15(T), was isolated from the thallus surface of the macroalga Fucus spiralis sampled on a rocky beach in Porto, Portugal. Based on the 16S rRNA gene sequence, strain FF15(T) was affiliated to the phylum Planctomycetes. This strain forms white colonies on modified M13 medium and the cells are pear-shaped, can form rosettes, divide by polar budding and are motile. The novel isolate is mesophilic and neutrophilic with an optimum growth temperature of about 30 degrees C and an optimum pH for growth between 6.5 and 7.5. It showed growth over a broad range of salinities (0-9% NaCl - optimum at 1.5%). No additional vitamins are required for growth. It is cytochrome c oxidase and catalase positive. The major respiratory quinone was menaquinone 6 (MK-6). Genome sequencing revealed a genome size of 6.37 Mbp and a DNA G + C content of 54.2%. Analysis of phylogenetic markers, including similarities of the 16S rRNA gene sequence, rpoB gene sequence, as well as Percentage of Conserved Proteins (POCP), Average Nucleotide Identity (ANI) and Average Amino Acid Identity (AAI), suggest the affiliation of strain FF15(T) to "Bremerella", a recently described genus in the family Pirellulaceae. Based on the genotypic, phylogenetic, chemotaxonomic, physiological and biochemical characterization, we described a new species represented by strain FF15(T) (=CECT 8078(T) = LMG 31936(T)), for which we propose the name Bremerella alba snov.
