Background Planctomyces limnophilus is a member of the order Planctomycetales, a group of budding mostly aquatic microorganisms lacking peptidoglycan and representing a phylogenetically distinct lineage within the domain Bacteria. The planctomycetes share a number of morphological features, having spherical or ovoid cells which bear crateriform structures and, in some cases, nonprosthecate appendages. The is the type strain and was isolated from the surface waters of a German lake. It is a pink to red color and is able to use glucose, N-acetylglucosamine, cellobiose, maltose, sucrose and trehalose as a sugar source, in addition to others. Its pH optimum range is 6.2 to 7.0 and grows optimally from 30 to 32 degrees Celsius. This organism has a distinct cell cycle, with sessile mother cells forming stalks that attach to surfaces or to other stalks and motile daughter cells that bud from the mother cell. Mother cells are spherical to ovoid with stalks composed of twisted fibrils. The diameter of the mother cell is 1.1 to 1.5 um. Multiplication occurs by budding on the distal cell pole, yielding daughter cells which are mono-trichously and polarly flagellated. Cells have rigid stalk fibers and can form multicellular rosettes. Although it lacks peptidoglycan it has a cell envelope which consists almost entirely of protein which is rich in proline and cysteine and is stabilized to a high degree by disulfide bonds. The sole respiratory lipoquinone is MK-6 (adapted from PMID 17978240 and DOI=10.4056/sigs.1052813). (EBI Integr8)
