A method is provided which uses existing populations of soil bacteria to produce quantities of melanin and pyomelanin and related pigments which will chemically reduce and chelate metals and sorb to various soil minerals to help immobilize such metals within a subsurface environment. Tyrosene and phenylalanine may be used to generate enhanced levels of melanin.
