Abstract
Planctomycetes is a phylum of environmentally important bacteria, which also receive significant attention due to their fascinating cell biology. Access to axenic Planctomycete cultures is crucial to study cell biological features within this phylum in further detail. In this study, we characterise three novel strains, Mal52T, Pan258 and CA54T, which were isolated close to the coasts of the islands Mallorca (Spain) and Panarea (Italy), and from Monterey Bay, CA, USA. The three isolates show optimal growth at temperatures between 22 and 24 °C and at pH 7.5, divide by polar budding, lack pigmentation and form strong aggregates in liquid culture. Analysis of five phylogenetic markers suggests that the strains constitute two novel species within a novel genus in the family Planctomycetaceae. The strains Mal52T (DSM 101177T = VKM B-3432T) and Pan258 were assigned to the species Symmachiella dynata gen nov., sp. nov., while strain CA54T (DSM 104301T = VKM B-3450T) forms a separate species of the same genus, for which we propose the name Symmachiella macrocystis sp. nov.
