Bioremediation
In-Situ and Ex-Situ Bioremediation • Ex-Situ • In-Situ
3 MAIN TYPES OF BIOREMEDIATION • Phytoremediation • Mycoremediation • Microbial Bioremediation
Phytoremediation • Plant Selection – Conditions, ability, rate • Concentration and size • 1990, now over 200 sites
Phytoremediation: Metal Hyperaccumulators
Phytoremediation • Chemically Altering Pollutant • Hydraulic Control • Volatilization
Mycoremediation • Fungi: Nature’s decomposers • Organic compounds, hydrocarbons • Enzymes • Hyperaccumulators
Mycoremediation Examples • Shiitake Mushroom – pentachlorophenol • Italian oyster mushrooms – Atrazine
Microbial Bioremediation • Use of Microorganisms, either natural or added • Promoted • Use of Contaminants as energy source • Aerobic vs Anaerobic (e donor)
Bioremediation and Genetic Engineering • Plants have been bred– poplar hybrids • Research • American University of Puerto Rico – Mercury Microbe • Lots of hopes • Concerns
