Phase-contrast micrographs of "Leptothrix discophora" strain LMG 8141. Two photographs of the strain are shown to demonstrate the observed variability in cellular morphology depending on growth conditions. False branchings are marked by an arrow. Scale Bar, 10 um. - Source:2Aerobic heterotroph
Aerobic, chemoorganoheterotrophs 2 4. Most species are restricted to natural, unpolluted environments with low concentrations of easily degradable organic nutrients. Only L. cholodnii is frequently detected in sewage sludge 4. It has been associated with the bulking in activated sludge WWTPs 3. Cells are straight rods, which may occur singly, in pairs or chains 2. Growth is filamentous under natural conditions due to the formation of tubular sheaths surrounding single and linear chains of cells 4. Poly-β-hydroxybutyrate is stored as reserve material 4. Oxidation of iron and manganese is typical for bacteria belonging to the genus 2 4. Nothing is known about the physiology of the genus in situ.
