20110033906 | METHOD FOR PRODUCING USEFUL SUBSTANCE FROM CELLULOSE-CONTAINING MATERIAL - The present invention provides a method for producing a useful substance efficiently from cellulose without using any cellulase preparation. According to the disclosures of the present specification, in the production of a useful substance from a cellulose-containing material, the cellulose-containing material is brought into contact with an ionic liquid to cause the ionic liquid to permeate the cellulose-containing material, and a carbon source comprising the cellulose in the cellulose-containing material is simultaneously saccharified and fermented by a cellulase-producing microorganism in the presence of the ionic liquid. | 02-10-2011 |
20110039316 | YEAST MUTANT AND SUBSTANCE PRODUCTION METHOD USING THE SAME - According to the present invention, the ability to produce a desired product is significantly improved and the growth rate and the fermentation rate are maintained at excellent levels for yeast upon production of a desired product with the use of yeast | 02-17-2011 |
20110151528 | PROCESS FOR PRODUCING ORGANIC ACID - This invention is intended to improve the efficiency of organic acid fermentation in a simple manner without mutant breeding, DNA recombination breeding, or other means, when producing an organic acid via fermentation with the use of yeast that produces the organic acid of interest. The efficiency of the yeast's ability to produce organic acid is significantly improved by treating yeast that produces an organic acid in an organic-acid-containing medium having a low pH value. | 06-23-2011 |
20130130328 | METHOD OF TREATING PLANT BIOMASS - Plant biomass is immersed in a solution that contains a polar solvent and an imidazolium salt that has a melting point of at least 100° C. As a result, the cellulose and hemicellulose present in the plant biomass are relaxed (decrystallized and depolymerized) and brought into an easy-to-degrade state. Reacting the immersed plant biomass with a cellulase produces saccharide at a high conversion efficiency. | 05-23-2013 |
20130217076 | POLYPEPTIDE CAPABLE OF ENHANCING CELLULOSIC BIOMASS DEGRADATION - The saccharification efficiency of cellulase is enhanced within reaction temperature regions of general fermenting microorganisms other than heat-resistant yeast. Cellulosic biomass is saccharified with cellulase in the presence of a polypeptide comprising the amino acid sequence shown in SEQ ID NO: 2 or 4 and having a function of enhancing the saccharifying activity of cellulase. | 08-22-2013 |
20130302854 | METHOD FOR TREATMENT OF CELLULOSIC BIOMASS AND METHOD FOR PRODUCTION OF SUGAR, ALCOHOL, OR ORGANIC ACID FROM CELLULOSIC BIOMASS - This invention is intended to improve saccharification efficiency by allowing cellulose and/or hemicellulose to relax sufficiently with an ionic liquid. Cellulose and/or hemicellulose is allowed to relax sufficiently with an ionic liquid through a step of soaking cellulosic biomass in a solution containing an ionic liquid and an alkali. | 11-14-2013 |
20140356925 | POLYPEPTIDE CAPABLE OF ENHANCING CELLULOSIC BIOMASS DEGRADATION - The saccharification efficiency of cellulase is enhanced within reaction temperature regions of general fermenting microorganisms other than heat-resistant yeast. Cellulosic biomass is saccharified with cellulase in the presence of a polypeptide comprising the amino acid sequence shown in SEQ ID NO: 2 or 4 and having a function of enhancing the saccharifying activity of cellulase. | 12-04-2014 |
20160040151 | PROTEIN HAVING XYLOSE ISOMERASE ACTIVITY AND USE OF SAME - A eukaryotic cell having xylose utilization ability. Provided is a protein that has xylose isomerase activity and has an amino acid sequence including, when aligned with an amino acid sequence expressed by SEQ ID NO:1, the 1st to 6th motifs expressed respectively by SEQ ID NOs:2 to 7 from the N-terminus side in the order described, and having, in place of asparagine (N) in an amino acid sequence of the 6th motif, another amino acid. | 02-11-2016 |
