Abstract

See full text

The invention provides method for producing butanediol and specifically 2,3-butanediol by anaerobic fermentation of a gaseous substrate comprising CO by a culture of at least one micro-organism. In accordance with particular methods of the invention, 2,3-butanediol is produced by anaerobic fermentation of substrates including carbohydrates and carbon monoxide. The invention further provides for the up-regulation of a native 2,3-butanediol dehydrogenase gene in the at least one micro-organism. The 2,3-butanediol can be further converted to compounds such as butene(s), butadiene and methyl ethyl ketone. These compounds can be further converted to chemical products such as 2-butanol.
