20150307905 | MANUFACTURING METHOD FOR A BUTANEDIOL, FABRICATION METHOD FOR A MICROBE FOR MANUFACTURING A BUTANEDIOL, AND MICROBE - A method of manufacturing a butanediol through 3-hydroxybutyryl-CoA that uses a microbe and/or a culture thereof and utilizes an enzyme reaction that is caused by an acyl-CoA reductase, wherein the microbe in the manufacturing method for a butanediol is characterized in that an activity of an acyl-CoA hydratase (EC number: 3. 1. 2. −) is deleted or reduced. | 10-29-2015 |
20150322625 | PRETREATMENT METHOD FOR CELLULOSE-CONTAINING BIOMASS, PRODUCTION METHOD FOR SACCHARIFYING BIOMASS COMPOSITION, AND SUGAR PRODUCTION METHOD - A pretreatment method (1) for improving saccharification performance of a cellulose-containing biomass as a saccharification starting material, which includes: step 1 of pulverizing cellulose-containing biomass; step 2 of subjecting the pulverized cellulose-containing biomass to hydrothermal treatment; and step 3 of finely pulverizing the cellulose-containing biomass subjected to the hydrothermal treatment. The fine pulverization in step 3 is performed by using a refiner or disc mill provided with a plate or disc without a flow passage leading from a center toward a circumferential direction. Also disclosed is (2) a method for producing a biomass composition for saccharification, which includes conducting the pretreatment method; and (3) a method for producing a sugar, which includes hydrolyzing a biomass composition for saccharification obtained by the production method. | 11-12-2015 |
20150337401 | PLANT-BIOMASS HYDROLYSIS METHOD - A method for hydrolyzing a plant biomass, including hydrothermal treatment in which an equivalent concentration of an acid equal to the total of 30 to 1,000% of the equivalent concentration of cations and equivalent concentration of hydroxide ions in a plant-biomass hydrolysis reaction solution is added to the reaction solution; and a method for producing glucose using the above method for hydrolyzing a plant biomass. The hydrothermal treatment is desirably conducted using a solid catalyst including a carbon material and an inorganic acid. The method can eliminate reaction-inhibiting factors due to cations existing in the reaction system to thereby attain a high glucose yield. | 11-26-2015 |
20150337402 | PLANT-BIOMASS HYDROLYSIS METHOD - A method for hydrolyzing a plant biomass, which includes a first process of heating a mixture containing a plant biomass, a solid catalyst, acid and water, and a second process for heating the mixture containing a solid containing a plant biomass and a catalyst separated from the reaction solution after the first process, acid and water, wherein the highest heating temperature in the second process is higher than that in the first process; and a method for producing glucose and xylose using the above-mentioned hydrolyzing method. In the method, both of glucose and xylose can be obtained efficiently from an actual biomass. | 11-26-2015 |
20150337403 | PLANT-BIOMASS HYDROLYSIS METHOD - A method for hydrolyzing a plant biomass, which includes hydrothermal treatment in the presence of an equivalent concentration of an acid equal to 30 to 1,000% of the equivalent concentration of cations in a plant-biomass hydrolysis reaction solution; and a method for producing glucose using the above method for hydrolyzing a plant biomass. The hydrothermal treatment is preferably conducted by using a solid catalyst comprising a carbon material and using inorganic acid as acid. The method eliminates reaction-inhibiting factors to thereby obtain a high glucose yield. | 11-26-2015 |
