- Rapidly increasing prices and dwindling supplies of petroleum have intensified interest in natural products as renewable raw materials for the chemical industry. Starch, a polysaccharide produced in great abundance in nature, is a prime candidate as a raw material because of its availability and relatively low cost, and because it can be converted readily into a variety of useful monomeric and polymeric products by chemical and biochemical means. Fermentation of starch to industrial-grade ethyl alcohol is becoming more economically competitive with the synthetic route due, largely, to the increasing cost of ethylene. Other biological conversions yield a variety of alcohols, ketones, and organic acids, and these too will become increasingly important as the petroleum situation worsens. Enzymatic conversion of starch to glucose, a useful starting compound for a variety of alcohols, acids, and polyols, proceeds readily and in near quantitative yield. Strach is an excellent source of renewable energy and raw materials.
