Abstract
Integrated processes are provided for the bioconversion of syngas to oxygenated organic compound with the ability to recycle sulfur nutrient and generate sulfur nutrient to the syngas fermentation in a safe and cost-effective manner. In preferred aspects of the invention, an acidogenic digestion is used to provide a biogas containing hydrogen sulfide, and then a methanogenic fermentation can follow to provide a methane-containing biogas that has a low hydrogen sulfide concentration.
