Abstract
A process for providing vicinal dimethyl long chain between alkyl groups of organic compounds is described. The process uses intact or disrupted cells of various species of bacteria, particularly Thermoanaerobacter sp., Sarcina sp. and Butyrivibrio sp. The process can be conducted in an aqueous reaction mixture at room temperatures.
Claims19
A process for formation of a long carbon chain compound which comprises;
- (a) reacting in an aqueous reaction mixture in absence of whole cells at a pH between pH 3 and pH 10 (1) a cellular material of a bacterium selected from the group consisting of Thermoanaerobacter, Sarcina and Butyrivibrio, wherein the cellular material is a cellular membrane fragment, (2) two molecules of long chain aliphatic compound having a terminal methyl group wherein at least one of the molecules is exogenous to and foreign to the bacterium and (3) an added hydrogen acceptor compound, wherein the two molecules of (2) form a carbon-carbon bond with the cellular membrane fragment as a catalyst, at a position of each molecule adjacent to the methyl group to provide the long chain carbon compound with vicinal dimethyls adjacent to the carbon-carbon bond;
- and
- (b) separating the long chain aliphatic compound with the vicinal dimethyls from the cellular membrane material.
