Abstract : Substitution of deuterium for hydrogen imparts an enhanced resistance to oxidation in materials such as lubricants. The exploitation of this and other novel properties of deuterated materials in applications of naval interest is only beginning to be realized. As an alternative to the conventional chemical methods of synthesizing deuterated compounds employing high temperature and reducing conditions, the present work explores the possible advantages of using algae grown in deuterium oxide (D2O) to provide completely deuterated precursors that are suitable for synthesizing a variety of lubricants. By proper choice of organism and growth conditions, it was possible to obtain dense cultures of algae containing 50 to 60% of their dry weight as long-chain fatty acids with different degrees of unsaturation. This report outlines strategies for synthesizing lubricant materials from these fatty acids and discusses the extension of biosynthesis to other deuterated materials such as polymers. Keywords: Biotechnology.
