Abstract:
1. A process for the microbial production of 1,3-propanediol and methane by a co-culture of microorganisms in a bioreactor, comprising: a) producing 1,3-propanediol in an anaerobic bioreactor from a substrate using a producer microorganism, wherein during the production of 1,3-propanediol at least one byproduct selected from the group consisting of alcohols, aldehydes, acids, hydrogen, carbon dioxide, and combinations thereof is also produced by the producer microorganism, b) producing methane using a methanogen, wherein during the production of the methane at least one byproduct from step (a) is consumed wherein said byproduct inhibits the production of 1,3-propanediol by said producer microorganism, and c) purifying the 1,3-propanediol.
