ABSTRACT:
Disclosed is a process for leaching selected metal compounds (e.g. gallium arsenide) from integrated circuits containing those compounds. The method includes placing the integrated circuits into a culture medium containing bacteria. Bacteria capable of leaching the metal compounds from the integrated circuits leach the metals from the integrated circuits. The bacteria preferably used will be ATCC 53921 and mutations and recombinants thereof. The integrated circuits are generally crushed to between 20 and -400 mesh before placement into the
