Abstract
This invention relates generally to method for producing products, particularly alcohols, by microbial fermentation. In particular, the invention relates to methods for increasing the efficiency of the fermentation, by providing a method for treating the used fermentation broth to produce a treated permeate which is then passed back to the bioreactor. The invention provides a method whereby at least one treatment step used to treat the permeated, produces a gaseous product which is then used in one or more stages of the fermentation process.
