Leptothrix - a sheated filamentous chemolitotroph
Leptothrix bacteria can be found in aquatic environments that contain sufficient amounts of organic matter. The optimal temperatures at which they grow are between 10-35oC and a pH of 6.5-7.5. Iron Bacteria can be found in streams, lakes, ponds and oceans. Some Leptothrix live in wastewater treatment plants where they may clog pipes and other parts of the system.
Leptothrix is not known to pose any environmental or human health risk.
