A Citizen`s Guide to Bioremediation
What is bioremediation? Bioremediation is a treatment process that uses naturally occurring microorganisms (yeast, fungi, or bacteria) to break down, or degrade, hazardous substances into less toxic or nontoxic substances. Microorganisms, just like humans, eat and digest organic substances for nutrients and energy. In chemical terms, 'organic' compounds are those that contain carbon and hydrogen ...
