Poribacteria
Fieseler,L, Horn, M., Wagner, M. and Hentschel1, U. (2004)Discovery of the Novel Candidate Phylum “Poribacteria” in Marine Sponges APPLIED AND ENVIRONMENTAL MICROBIOLOGY 70: 3724–3732
Bacterial types in the sponge Aplysina aerophoba1 Long rods with membrane-bound nuclear region and S-layer-type outer membrane, cell division by septation2 Short fat rods with membrane-bound nuclear region and electron-dense cytoplasm3 D-shaped cells with clear membrane-bound nuclear region and S-layer-type outer membrane4 Rods with clear membrane-bound nuclear region and gram-negative outer membrane5 Rods with clear, membrane-bound nuclear region and S-layer-type outer membrane6 Rods with membrane-bound compartment that is devoid of DNA; the compartment contains most of the RNA, while the DNA is restricted to the cytoplasm; the outer membrane contains budding appendages; there is an unusually wide periplasmic space and a phenotypic resemblance to G. aurantiaca
