Abstract

Provided are a method for treating a saccharide solution, which comprises subjecting a saccharide solution containing at least one selected from the group consisting of a carbonyl compound and an unsaturated alcohol other than a saccharide to hydrogenation reaction to hydrogenate the carbonyl compound and/or the unsaturated alcohol contained in the saccharide solution, a hydrogenated saccharide solution obtained by treating with the treatment method, and a method for producing an organic compound having a process of obtaining the organic compound by acting a microorganism having an organic material producing ability on an organic raw material containing the hydrogenated saccharide solution.

First claim

The invention claimed is:

1. A method for producing an organic compound, the method comprising:
hydrogenating a saccharide solution which comprises saccharide and at least one selected from the group consisting of a carbonyl compound and an unsaturated alcohol at a temperature of 120° C. or less, wherein the carbonyl compound is other than a saccharide, and
producing an organic material in which a microorganism capable of producing an organic material is acted in an aqueous medium on an organic raw material containing the saccharide solution, and in which the microorganism contacts the hydrogenated saccharide solution, after the hydrogenating of the saccharide solution.

2. The method for producing an organic compound according to claim 1 , wherein the producing of the organic material is carried out under an anaerobic atmosphere.

3. The method for producing an organic compound according to claim 1 , further comprising purifying the organic compound obtained in the producing of the organic material.

4. The method for producing an organic compound according to claim 1 , wherein the aqueous medium comprises at least one selected from a carbonate ion, a bicarbonate ion, and a carbon dioxide gas.

5. The method for producing an organic compound according to claim 1 , wherein the organic compound is at least one selected from an alcohol, an amine, a carboxylic acid and a phenol.

6. The method for producing an organic compound according to claim 5 , wherein the alcohol is an aliphatic alcohol having 2 to 10 carbon atoms.

7. The method for producing an organic compound according to claim 5 , wherein the carboxylic acid is an aliphatic carboxylic acid having 2 to 10 carbon atoms.

8. The method according to claim 1 , wherein the microorganism is at least one selected from the group consisting of coryneform bacterium, Escherichia coli , a bacterium of the genus Anaerobiospirillum , a bacterium of the genus Actinobacillus , a bacterium of the genus Mannheimia , a bacterium of the genus Basfia , a bacterium of the genus Zymomonas , a bacterium of the genus Zymobacter , a fungus and a yeast.

9. The method according to claim 1 , wherein the microorganism can utilize pentose nutritionally.

10. The method according to claim 9 , wherein the pentose is xylose.

11. The method according to claim 10 , wherein the microorganism is a microorganism in which a xylose isomerase activity is provided or enhanced by introducing a gene which encodes a protein having a xylose isomerase activity to a parental strain of the microorganism.

12. The method according to claim 11 , wherein the microorganism is a microorganism in which a xylulokinase activity is provided or enhanced by introducing a gene which encodes a protein having xylulokinase activity to a parental strain of the microorganism.

13. The method for producing an organic compound according to claim 1 , wherein the hydrogenation of the saccharide solution is carried out at a temperature from 20 to 120° C.
