    Abstract: Processes for the bioconversion of syngas to oxygenated organic compound are disclosed that reliably, cost-effectively and efficiently supply sulfur nutrient to microorganisms contained in acidic, aqueous fermentation menstrua. In the processes of this invention, at least a portion of the sulfur nutrient for the population of microorganisms in the aqueous menstruum is provided as calcium sulfite, and the presence of undissolved calcium sulfite is maintained in the aqueous menstruum.

    Abstract: A process for conversion of syngas to liquid products that serve as surface acting agents uses the gas stream at a relatively low pressure to eliminate the use of a compressor. The process uses a liquid stream as the primary energy input to a gas injector that intensely mixes gas and the liquid with reduced compression costs while the presence of the liquid product maintains the gas-liquid dispersion as it flows downward to build a static pressure head. The process lowers the required gas pressure by adjusting the elevation of the gas injector such that a conduit receives the gas-liquid dispersion from the outlet of the injector and confines it as it travels downward to enter the bottom of a column of liquid. The liquid product provides a surface acting agent that prolongs the creation and duration of microbubbles in the gas-liquid dispersion.

    Abstract: The invention relates to improvements in the production of butanol and butyrate by microbial fermentation, particularly to production of alcohols by microbial fermentation of a substrate comprising CO and the addition of an inorganic sulfur additive. It more particularly relates to the provision of an inorganic organic sulfur source to a fermentation system such that one or more micro-organisms convert a substrate comprising CO to butanol. In one aspect the invention uses a sulfur additive comprising inorganic sulfur compounds having a +2 to a +4 sulfur oxidation state that produces sulfur oxoanions and hydrosulfur oxoanions in an aqueous fermentation medium.

    Abstract: Integrated processes are disclosed for reducing the carbon foot print related to the use of non-renewable hydrocarbon gas streams for producing alcohols by anaerobic bioconversion of reformed gas. These processes combine renewable and non-renewable gas sources of hydrogen, carbon monoxide and carbon dioxide to produce alcohol. Thus the invention found a highly a practical way to make use of non-renewable carbon oxide sources while still lowering the carbon footprint of such alcohols produced thereby, especially when combined with corn ethanol production. In the case of motor fuel use, the renewable portion of the alcohol produced in this manner provides a reduction in greenhouse gases by 50% or more when compared to gasoline.
