NOVELTY - Producing one or more products from a gas stream produced in an ammonia production process, comprises (a) converting at least a portion of a gas stream comprising methane to a substrate comprising carbon monoxide, carbon dioxide and hydrogen, and (b) passing at least a portion of the substrate to a bioreactor containing a culture of one or more microorganisms, anaerobically fermenting at least a portion of the substrate comprising carbon monoxide and hydrogen to produce one or more products and an exhaust gas stream comprising hydrogen and carbon dioxide.    USE - The method is useful for producing one or more products from a gas stream produced in an ammonia production process.    ADVANTAGE - The method is capable of producing one or more products from a gas stream produced in an ammonia production process with high specificity and yield, and without toxicity in an economical manner.    DETAILED DESCRIPTION - Producing one or more products from a gas stream produced in an ammonia production process, comprises either (a) converting at least a portion of a gas stream comprising methane to a substrate comprising carbon monoxide, carbon dioxide and hydrogen, and (b) passing at least a portion of the substrate to a bioreactor containing a culture of one or more microorganisms, anaerobically fermenting at least a portion of the substrate comprising carbon monoxide and hydrogen to produce one or more products and an exhaust gas stream comprising hydrogen and carbon dioxide, or (a1) converting at least a portion of a gas stream comprising methane to a substrate comprising carbon monoxide, carbon dioxide and hydrogen, (b1) passing at least a portion of the substrate to a bioreactor containing a culture of one or more microorganisms, anaerobically fermenting at least a first portion of the substrate comprising carbon monoxide and hydrogen to produce one or more products comprising alcohols and/or acids and an exhaust gas stream comprising hydrogen and carbon dioxide, (c1) passing a second portion of the substrate to a water gas shift reactor (114) operated at conditions to produce an effluent stream comprising carbon dioxide and hydrogen, (d1) passing the exhaust gas stream and the effluent stream of (c1) to a separation zone operated at conditions to separate at least a portion of the carbon dioxide and produce a second effluent stream rich in hydrogen and carbon dioxide stream, and (e1) passing the second effluent stream to an ammonia synthesis zone operated at conditions to produce ammonia.
