Cells of strain ElP^T are spherical, form pink colonies and display typical planctomycetal characteristics including division by budding and presence of crateriform structures. Strain ElP^T has a mesophilic (optimum at 30 °C) and neutrophilic (optimum at pH 7.5) growth profile, is aerobic and heterotrophic. It reaches a generation time of 29 h (µ_max = 0.024 h^-1). The strain has a genome size of 9.40 Mb with a G + C content of 71.1% and harbours five plasmids, the highest number observed in the phylum Planctomycetes thus far. Phylogenetically, the strain represents a novel speciesAntonie van LeeuwenhoekTautonia plasticadhaerens sp. nov., a novel species in the family Isosphaeraceae isolated from an alga in a hydrothermal area of the Eolian Archipelago.PMC7716859KA 4967/1-1JO 893/4-1ALWOP.308024002002Kallscheuer NPeeters SHJogler CWiegand SJetten MSMRohde MJogler MBoedeker CHeuer AfalseTautonia plasticadhaerens sp. nov., a novel species in the family Isosphaeraceae isolated from an alga in a hydrothermal area of the Eolian Archipelago.A novel planctomycetal strain, designated ElP^T, was isolated from an alga in the shallow hydrothermal vent system close to Panarea Island in the Tyrrhenian Sea.
