Abstract: Procedimiento para producir una β-glucosidasa mutante derivada de un termófilo que tiene fijada selectivamente a ella una cadena de azúcares y también tiene una actividad glucosidasa, que comprende: (i) preparar ADN que codifica una β-glucosidasa mutante derivada de un termófilo introduciendo una secuencia de ADN que codifica Asn-X-Ser o Asn-X-Thr (en las que, X es cualquier aminoácido excepto prolina) en ADN que codifica una β-glucosidasa derivada de un termófilo que está originalmente desprovista de una secuencia de glucosilación y, además, añadiendo una secuencia de ADN que codifica una secuencia señal de secreción al ADN que codifica una β-glucosidasa mutante, (ii) introducir el ADN que codifica una β-glucosidasa mutante al que se le ha añadido la secuencia de ADN que codifica la secuencia señal de secreción en un microorganismo eucariota, de modo que una β-glucosidasa mutante codificada por el ADN de la β-glucosidasa mutante se exprese como una proteína secretora, y (iii) aislar y purificar la β-glucosidasa mutante expresada de este modo como una proteína secretora.

Abstract: [Problem] To provide a method for producing a chemical substance with high yield using a mixed sugar composed of a hexose and a pentose as a fermentation raw material. [Solution] Provided is a method for producing a chemical substance through continuous fermentation, said method comprising filtrating a culture solution of a microorganism using a separation membrane, retaining an unfiltered portion of the culture solution in the culture solution or refluxing the unfiltered portion through the culture solution, adding a new fermentation raw material to the culture solution and collecting a product from the culture solution, wherein the fermentation raw material comprises a pentose and a hexose and the microorganism has a pathway through which a pentose can be metabolized with a pentose isomerase.

Abstract: Disclosed is a method for producing 1,5-pentanediamine through fermentation using a microorganism, said microorganism having LDC gene in the chromosome and showing regulated secondary production of L-lysine. In the method for producing 1,5-pentanediamine whereby 1,5-pentanediamine is produced by a coryneform bacterium having a gene encoding lysine decarboxylase in the chromosome, said coryneform bacterium continuously maintains a lysine decarboxylase activity of 50 mU/mg protein or greater during the culture.
