Leptothrix (bacterium)

This article is about the group of bacteria. For the genus of spiders, see Leptothrix (spider).

Leptothrix is a genus of Gram-negative bacteria in the class Betaproteobacteria.^[3] The name is from the Greek leptos thrix (literally 'fine hair').^[1] They occur in standing or slow-flowing, ferruginous, neutral to slightly acidic fresh waters with only low concentrations of organic matter. The energy metabolism of Leptothrix is strictly aerobic, oxidative, and chemoorganoheterotrophic. Five species are known: L. ochracea, L. discophora, L. cholodnii, L. lopholea, and L. mobilis.
