Abstract: An alcohol production method whereby high quality alcohol can be easily and effectively produced includes a step in which an alcohol solution, which contains sugar and/or sugar alcohol as an impurity and an alcohol other than sugar alcohol as a main component, has the sugar and/or sugar alcohol adsorptively removed therefrom by contacting the alcohol solution with one type or a mixture of two or more types of adsorbents selected from zeolite, an ion-exchange resin, silica alumina, and alumina.

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: By filtering, through an ultrafiltration membrane of a 600-2000 fraction molecular weight, an aqueous sugar solution obtained by hydrolyzing a cellulose-containing biomass, removing fermentation inhibitors on the permeated side and recovering the sugar solution from the un-permeated side, this method is capable of manufacturing a sugar solution with an extremely low amount of fermentation inhibitors.

Abstract: The problem addressed by the present invention is manufacturing a sugar solution in which the amount of fermentation inhibiting substances is extremely low. The present invention is a method that concentrates an aqueous solution of sugar derived from cellulose using a nano filtering membrane and/or a reverse osmosis membrane and is a method for manufacturing a sugar solution in which an anionic polymer is added and fermentation inhibiting substances are eliminated on the permeated side of a nano filtration membrane and/or a reverse osmosis membrane.

Abstract: A method for producing a diol or triol, which has a step of removing impurities contained in a diol- or triol-containing solution, is provided. In the method, a diol-or triol-containing solution is filtered through a nanofiltration membrane having a polyamide-containing functional layer. The diol-or triol--containing solution is then collected from the permeate flow of the nanofiltration membrane.

Abstract: Provided is a polyester with an excellent color tone, and improved molding stability and mechanical properties. This improvement is achieved by controlling the electrical conductivity of the diol composition, which is a raw material for the polyester, to be between 0.6 mS/m and 30 mS/m, and preferably by controlling the pH of the diol composition to be between 5 and 7.5, thereby reducing the heating weight loss ratio of the polyester.

Abstract: Disclosed is a hollow fiber membrane module (1) for use in the production of a chemical substance, which can be used in the continuous fermentation that comprises filtrating a fermentation culture of a microorganism or a cultured cell through a hollow fiber membrane, collecting a chemical substance from a filtrate, retaining a concentrated solution in the fermentation culture or refluxing the concentrated solution, and further adding a fermentation raw material to the fermentation culture. In the hollow fiber membrane module (1), multiple hollow fiber membrane bundles are accommodated in a tubular case, at least one end part of each of the hollow fiber membrane bundles is fixed onto the tubular case in such a manner that the end surface of each of the hollow fiber membranes is opened by means of a hollow-fiber-membrane-bundling material, and the hollow-fiber-membrane-bundling material comprises a synthetic resin that exhibits a hardness retention rate of 95% or more after the material is brought into contact with a saturated water vapor at 121°C for 24 hours. The hollow fiber membrane module (1) can keep substance productivity at a high level and can be used in the production of a chemical substance by a sterilizable continuous fermentation method.

Abstract: Provided is an efficient method for decomposing biomass, which involves producing glucosidase in which the cellulose degrading efficiency is improved, and using said glucosidase. Specifically, provided is a method for producing a mutant glucosidase wherein a DNA encoding a secretion signal sequence and a DNA encoding Asn-X-Ser or Asn-X-Thr are introduced into a DNA encoding a glucosidase from a thermophile, and the resulting product is introduced into a eukaryotic microorganism and expressed as a secretory protein. Also provided are an enzyme composition containing said mutant glucosidase, and a biomass hydrolysis method using said enzyme composition.
