説明
<jats:title>Abstract</jats:title><jats:p>Planctomycetes are intriguing microorganisms that apparently lack peptidoglycan, a structure that controls the shape and integrity of almost all bacterial cells. Therefore, the planctomycetal cell envelope is considered exceptional and their cell plan uniquely compartmentalized. Anaerobic ammonium-oxidizing (anammox) Planctomycetes play a key role in the global nitrogen cycle by releasing fixed nitrogen back to the atmosphere as N<jats:sub>2</jats:sub>. Here using a complementary array of state-of-the-art techniques including continuous culturing, cryo-transmission electron microscopy, peptidoglycan-specific probes and muropeptide analysis, we show that the anammox bacterium <jats:italic>Kuenenia stuttgartiensis</jats:italic> contains peptidoglycan. On the basis of the thickness, composition and location of peptidoglycan in <jats:italic>K. stuttgartiensis</jats:italic>, we propose to redefine Planctomycetes as Gram-negative bacteria. Our results demonstrate that Planctomycetes are not an exception to the universal presence of peptidoglycan in bacteria.</jats:p>
