Converting Organic Compounds to Useful Products

Playa lakes associated with cattle feedlots commonly contain high levels of organic compounds. These organics degrade water quality and have the potential to pollute both surface and ground water. Graduate students are working on a number of projects using this nutrient-rich water to produce single cell protein and microalgae. These products, processed into animal feeds, are being evaluated as dietary ingredients for fish. Improvement in water quality includes reduction of the biochemical oxygen demand and levels of nitrogenous compounds.
