Abstract: Preliminary results on the novel use of the bacterium Thiobucillus ferrooxiduns (ATCCI 3598 and ATCC3302Q) for the micro-machining (or biomachining) of metals are reported. Biomacnining is a controlled microbiological process to selectively form microstructures on a metal work-piece by metal removal (or dissolution) using microorganisms. Applying copper and mild steel as work-pieces, i t was shown that the mass removed increased proportionately with machining time. In another experiment, the work-pieces were …
