Lignipirellula cremea gen. nov., sp. nov., a planctomycete isolated from wood particles in a brackish river estuary
Summary
Researchers isolated and described a new species of bacteria, Lignipirellula cremea, found growing on wood submerged near a wastewater treatment plant in Germany, adding to our understanding of the microbial communities that colonize surfaces in polluted aquatic environments.
A novel planctomycetal strain, designated Pla85_3_4<sup>T</sup>, was isolated from the surface of wood incubated at the discharge of a wastewater treatment plant in the Warnow river near Rostock, Germany. Cells of the novel strain have a cell envelope architecture resembling that of Gram-negative bacteria, are round to pear-shaped (length: 2.2 ± 0.4 µm, width: 1.2 ± 0.3 µm), form aggregates and divide by polar budding. Colonies have a cream colour. Strain Pla85_3_4<sup>T</sup> grows at ranges of 10-30 °C (optimum 26 °C) and at pH 6.5-10.0 (optimum 7.5), and has a doubling time of 26 h. Phylogenetically, strain Pla85_3_4<sup>T</sup> (DSM 103796<sup>T</sup> = LMG 29741<sup>T</sup>) is concluded to represent a novel species of a novel genus within the family Pirellulaceae, for which we propose the name Lignipirellula cremea gen. nov., sp. nov.
