The invention relates to a method for treating a solution containing a saccharide comprising a heat treatment step of heating the saccharide solution at a temperature of 100&#xb0; C. or higher and 180&#xb0; C. or lower and a reduction step of reacting a reducing agent with the saccharide solution heated in the heat treatment step, a method for producing a treated saccharide solution using the treatment method, a treated saccharide solution obtained through treatment by the treatment method, a method for producing an organic compound comprising an organic-matter production step of obtaining an organic compound by causing a microorganism capable of producing organic matter to act on an organic raw material containing the treated saccharide solution and a method for culturing a microorganism using the treated saccharide solution as a carbon source.

Treatment method of saccharide solution

The present invention aims to provide a polyester polyol having favorable reactivity and a favorable color tone, which can be used for obtaining a polyurethane having an excellent balance of flexibility, mechanical strength, and chemical resistance, and a method for producing the polyester polyol. The object can be achieved with a polyester polyol in which an aliphatic diol contains as a structural unit 1,10-decanediol derived from a biomass resource, and in which the aldehyde body content in the polyester polyol is 0.01 to 0.5% by weight, and a method for producing the polyester polyol.

Polyester polyol, polyurethane resin, and production processes therefor

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.
