Abstract: Disclosed is a lactic acid production method by separating lactic acid produced in a culture solution by means of the fermentation culture of a microorganism. Specifically disclosed is a lactic acid production method, which comprises: a step (A) of filtering the culture solution through a nano-filtration membrane; and a step (B) of distilling a lactic-acid-containing solution produced in the step (A) under a pressure ranging from 1 Pa to the atmospheric pressure (inclusive) at a temperature ranging from 25 to 200 DEG C (inclusive) to collect lactic acid. The method can effectively remove an inorganic salt dissolved in a fermentation culture solution or contained in the fermentation culture solution in the form of a poorly soluble solid material by a simple manipulation, enables to prevent the racemization or oligomerization of lactic acid during the process of producing lactic acid, and therefore can produce lactic acid in a high yield.

Abstract: An alcohol production method whereby high quality alcohol can be easily and effectively produced includes a step in which an alcohol solution, which contains sugar and/or sugar alcohol as an impurity and an alcohol other than sugar alcohol as a main component, has the sugar and/or sugar alcohol adsorptively removed therefrom by contacting the alcohol solution with one type or a mixture of two or more types of adsorbents selected from zeolite, an ion-exchange resin, silica alumina, and alumina.

Abstract: Highly pure butanol can be produced by a method for producing butanol, the method comprising: Step A, wherein a butanol-containing solution is filtered through a nanofiltration membrane and a butanol-containing solution is recovered from the permeate side; Step B, wherein the butanol-containing solution obtained in Step A is passed through a reverse osmosis membrane and thereby concentrated to cause two-phase separation into a butanol phase and an aqueous phase; and Step C, wherein butanol is recovered from the butanol phase obtained in Step B.

Abstract: A method for selective production of µ-caprolactam, wherein a substance inducible from a biomass resource is used as a material; the reaction process is short; ammonium sulfate is not produced as a by-product; and production of by-products is suppressed; is disclosed. The method for producing µ-caprolactam comprises the step of reacting a particular compound inducible from a biomass resource, such as ±-hydromuconic acid, 3-hydroxyadipic acid, or 3-hydroxyadipic acid-3,6-lactone, or a salt thereof with hydrogen or ammonia.
