Abstract:
A method for providing a metabolizable chemical to a microorganism in the presence of water over a period of time which comprises:introducing into the water an admixture of multiple particles which are water insoluble with micropores throughout each of the particles, the micropores of at least one particle containing a microorganism and the micropores of at least one particle containing a chemical selected from the group consisting of an electron acceptor, an electron donor, substances for modification of pH, a nutrient medium for the microorganism and mixtures thereof, and said chemical being metabolizable by the microorganism, wherein said chemical is exposed on a surface of each of the particles other than the particles containing the microorganism, and the particles containing the chemical release the chemical over a period of time to the particles containing the microorganism in the water such that the microorganism is able to metabolize the chemical over the period of time.
