White Paper: In-Pipe Technology Microbiology Metabolic Pathways Introduction

In-Pipe Technology (IPT) bacteria are heterotrophic bacteria commonly found in soil. They are part of a group of microorganisms termed "decomposers" and are "generalists" in regards to their broad capabilities of using many different carbon sources to fuel their metabolism. In their natural soil environment, similar bacteria feed on decaying material and by-products produced by the other organisms in the food chain. These organisms contain a great diversity of enzymes that are both excreted and retained within the cells and are very active degrading complex organic matter. The IPT bacteria can be found in the human gastrointestinal tract but in very low numbers and usually in a low metabolic state. They are naturally occurring and are not pathogenic or genetically modified. IPT bacteria can operate using aerobic respiration, fermentation, and anaerobic respiration using nitrate or fumarate as the final electron acceptor. They are vigorous growers and are more than capable of degrading pollutants normally found in municipal wastewater.
