The invention relates to methods of capturing carbon by microbial fermentation of a gaseous substrate comprising CO. The methods of the invention include converting CO to one or more products including alcohols and/or acids and optionally capturing CO2 to improve overall carbon capture. In certain aspects, the invention relates to processes for producing alcohols, particularly ethanol, from industrial waste streams, particularly steel mill off-gas.

Carbon capture in fermentation

The invention relates to improvements in the production of alcohols by microbial fermentation, particularly to production of alcohols by microbial fermentation of substrates comprising CO. It more particularly relates to the provision of an improved fermentation media, comprising nickel, to a fermentation system such that one or more micro-organisms convert a substrate comprising CO to one or more alcohols, such as ethanol. In particular embodiments, a microbial culture is provided with at least 10 &#x3bc;M nickel, such that CO uptake by the microbial culture increases and ethanol productivity improves.
