“…The surface quality deteriorated rapidly, and at the end of the 2 h, the surface roughness of the three kinds of materials reached the worst, and then became stable. Beyond the 2 h, it no longer increased significantly, but fluctuated within certain limits and then reached the stable stage eventually (Yang et al, 2009). …”

Abstract-Micro-manufacturing is one of the fastest growing technologies and non-traditional machining processes have been found to be beneficial for micro manufacturing using low density of energy for metal removal. In biomachining the metabolic function of the bacterium is utilized, no physical or chemical energy needs to be focused at the machining point, thereby avoiding the possibility of generating a damaged layer or a heat-affected zone in the machined surface. In biomachining, microorganisms are used to create the desired part(s) of the metals to the required dimensions. In this study an attempt has been made to understand the basics of "Biomachining" along with the factors effecting the output performance characteristics.

Biomachining has become a promising alternative to micromachining metal pieces, as it is considered more environmentally friendly than their physical and chemical machining counterparts. In this research work, two strategies that contribute to the development of this innovative technology and could promote its industrial implementation were investigated: preservation of biomachining microorganisms (Acidithiobacillus ferrooxidans) for their further use, and making valuable use of the liquid residue obtained following the biomachining process. Regarding the preservation method, freeze‐drying, freezing, and drying were tested to preserve biomachining bacteria, and the effect of different cryoprotectants, storage times, and temperatures was studied. Freezing at –80°C in Eppendorf cryovials using betaine as a cryoprotective agent reported the highest bacteria survival rate (40% of cell recovery) among the studied processes. The treatment of the liquid residue in two successive stages led to the precipitation of most of the total dissolved iron and divalent copper (99.9%). The by‐products obtained (iron and copper hydroxide) could be reused in several industrial applications, thereby enhancing the environmentally friendly nature of the biomachining process.
