Abstract
Official abstract text for this publication.
A method of producing THB with improved efficiency is provided. Provided is a method of producing trihydroxybenzene (THB), the method comprising a step of heating a bacterial culture liquid comprising deoxy-scyllo-inosose (DOI) at a high temperature of no lower than 80° C. to obtain a product solution comprising trihydroxybenzene (THB).
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of producing trihydroxybenzene (THB), the method comprising a step of heating a bacterial culture liquid comprising deoxy-scyllo-inosose (DOI) at a high temperature of 130 to 180° C. to obtain a product solution comprising trihydroxybenzene (THB), wherein the method further comprises, before the heating, a step of culturing a DOI-synthesizing bacteria in a liquid culture medium under a DOI-synthesizing condition, wherein the liquid culture medium after the culturing, without purifying the DOI or only with removal of the bacteria, provides the bacterial culture liquid to be heated. 2. The method according to claim 1 , wherein the bacterial culture liquid comprises at least 1 g/L DOI accumulated from culturing DOI-synthesizing bacteria. 3. The method according to claim 1 , wherein the heating at the high temperature is carried out for at least 30 seconds. 4. The method according to claim 1 , further comprising a step of separating the trihydroxybenzene (THB) from the product solution. 5. The method according to claim 4 , wherein the step of separating comprises solvent extraction. 6. The method according to claim 5 , wherein the solvent in the solvent extraction is ethyl acetate.
