Tuwongella immobilis gen. nov., sp. nov., a novel non-motile bacterium within the phylum Planctomycetes.

ABSTRACT: A gram-negative, budding, catalase negative, oxidase positive and non-motile bacterium (MBLW1^T) with a complex endomembrane system has been isolated from a freshwater lake in southeast Queensland, Australia. Phylogeny based on 16S rRNA gene sequence analysis places the strain within the family Planctomycetaceae, related to Zavarzinella formosa (93.3 %), Telmatocola sphagniphila (93.3 %) and Gemmata obscuriglobus (91.9 %). Phenotypic and chemotaxonomic analysis demonstrates considerable differences to the type strains of the related genera. MBLW1^T displays modest salt tolerance and grows optimally at pH values of 7.5-8.0 and at temperatures of 32-36 °C. Transmission electron microscopy analysis demonstrates the presence of a complex endomembrane system, however, withou
