Methanol, a potential feedstock for biotechnological processes

A wide variety of bacteria and yeasts is able to grow in inexpensive synthetic media with methanol as the sole or major source of carbon and energy. This is due to the presence of a few unique enzymes which enable these organisms to generate metabolic energy and synthesize cell constituents from this one-carbon substrate. In the chemical industry there is currently much interest in the production of fuels and chemicals from methanol. As a feedstock for industrial fermentations methanol is also attractive because of its low cost, ease of handling and abundant availability. In many countries methanol-utilizing microbes are being studied and their potential utility in biotechnological processes is explored. These studies are aimed at making use of their characteristic properties, exploiting known organisms and new strains for improving existing processes and developing novel products.
