Abstract: Disclosed is a method for producing 1,3-butadiene and/or 3-buten-2-ol from 2,3-butanediol with high selectivity without using a radioactive substance. The method for producing 1,3-butadiene and/or 3-buten-2-ol comprises the step of dehydrating 2,3-butanediol in the presence of scandium oxide. The method enables the production of 1,3-butadiene and/or 3-buten-2-ol from 2,3-butanediol with high selectivity without using a radioactive substance.

Abstract: To control the flow rate of a liquid culture medium in a membrane separation tank without affecting the culture conditions in a culture tank and to increase the production efficiency of a chemical by inhibiting the precipitation of a microorganism or culture cells, provided is a method for producing a chemical which comprises culturing a microorganism or culture cells in a culture tank, feeding the liquid culture medium from the culture tank to a membrane separation tank and filtering the same through a separation membrane, collecting a fermentation product as the chemical from the permeate and, at the same time, returning the unfiltered liquid culture medium not having been filtered in such a manner as combining the same with the liquid culture medium in the upstream side of the membrane separation tank, wherein a portion of the liquid culture medium fed from the culture tank is passed outside the membrane separation tank depending on the inflow side pressure of the membrane separation tank.

Abstract: The present invention provides a process for producing a sugar solution having improved fermentability from cellulosic biomass as a raw material. This process for producing a sugar solution comprises: a step in which an alkali is added to a cellulosic-biomass-derived concentrated sugar solution to regulate the pH thereof to 7 or higher, thereby precipitating insoluble substances containing at least magnesium; and a step in which the resulting mixture is filtered with a microfiltration membrane to remove the insoluble substances and obtain a sugar solution as the penetrant.

Abstract: A process produces 1,4-butanediol by purifying 1,4-butanediol originated from a fermentation broth, by which process 1,4-butanediol having properties suited as a material of producing a polyester is obtained, which 1,4-butanediol enables to reduce by-production of tetrahydrofuran during the esterification reaction and to reduce the delay in polymerization. The process of producing 1,4-butanediol includes adding an alkaline substance other than an ammonia or an amine to an aqueous 1,4-butanediol-containing solution originated from a fermentation broth; distilling the resulting mixture; and recovering a 1,4-butanediol- containing solution from the vapor flow.
