ABSTRACT:
A method for in situ bioremediation of contaminants in the environment is described. The method includes adding an electron donor to ground water in an amount sufficient for a microbe in the ground water to use the electron donor for reducing the contaminant into an innocuous derivative thereof. Illustratively, the electron donor contains about 0.1 to 75% by weight of chitin, such as crustacean shell, partially deproteinized crustacean shell, ground mushrooms, or a fungal fermentation broth. The chitinous electron donor can be added to the ground water as a particulate solid or aqueous slurry.
