  • METHOD OF PRODUCING 2,3-BUTANEDIOL
    Publication number: 20160298144
    Abstract: A method of producing 2,3-butanediol includes the steps of: culturing a microorganism belonging to the genus Zymobacter in a fermentation feedstock containing a carbon source (Step A); and purifying 2,3-butanediol from culture liquid obtained in this step (Step B). In this method, the carbon source contains pentose, and the microorganism belonging to the genus Zymobacter has a capacity to metabolize pentose.

  • METHOD OF PRODUCING CHEMICAL SUBSTANCE
    Publication number: 20150024445
    Abstract: A method of producing a chemical product by continuous fermentation includes filtering a culture liquid of a microorganism(s) through a separation membrane; retaining unfiltered liquid in, or refluxing unfiltered liquid to, the culture liquid; adding a fermentation feedstock to the culture liquid; and recovering a product in the filtrate, wherein the fermentation feedstock contains pentose and hexose, and wherein the microorganism(s) is/are a microorganism(s) having a pathway in which pentose reductase and pentol dehydrogenase are used to metabolize pentose.

  • PROCESS FOR PRODUCING 2,3-BUTANEDIOL
    Publication number: 20140238841
    Abstract: A method of producing 2,3-butanediol includes subjecting a 2,3-butanediol culture liquid produced by microbial fermentation to nanofiltration membrane treatment and ion-exchange treatment (Step A), and then adding an alkaline substance and performing distillation (Step B).
