More specifically methods of increasing the butanediol productivity from the anaerobic fermentation of a substrate comprising carbon monoxide or carbon monoxide and hydrogen by one or more caboxydotrophic acetogenic bacteria are disclosed. The method includes supplying a hydrogen depleted substrate to increase butanediol productivity. The method includes producing butanediol at a volumetric productivity rate of at least 15 g/L/day.
