Abstract: The present invention aims to provide a method for producing polybutylene terephthalate (PBT) with an excellent color using biomass-derived 1,4-butanediol (BG). The invention relates to a method for producing PBT comprising a step of subjecting a diol component containing raw material 1,4-BG having a nitrogen content of 0.01 to 50 ppm by mass and a dicarboxylic acid component to esterification or ester-exchange reaction, and a polycondensation reaction step for obtaining PBT from the reactant, wherein the content of gamma butyrolactone in the raw material 1,4-BG is 1 to 100 ppm by mass.

Abstract: A process of isolating 1,4-butanediol (1,4-BDO) from a fermentation broth includes separating a liquid fraction enriched in 1,4-BDO from a solid fraction comprising cells, removing water from said liquid fraction, removing salts from said liquid fraction, and purifying 1,4-BDO. A process for producing 1,4-BDO includes culturing a 1,4-BDO-producing microorganism in a fermentor for a sufficient period of time to produce 1,4-BDO. The 1,4-BDO-producing microorganism includes a microorganism having a 1,4-BDO pathway having one or more exogenous genes encoding a 1,4-BDO pathway enzyme and/or one or more gene disruptions. The process for producing 1,4-BDO further includes isolating 1,4-BDO.

Abstract: At the time of producing a polyester by using a dicarboxylic acid component and a biomass-resource-derived diol as raw materials, a polyester is efficiently produced with good color tone, as the raw material diol derived from biomass resources, a diol in which the content of a cyclic carbonyl compound having a carbon atom number of 5 or 6 is from 0.01 to 12 ppm by mass, is used, and by controlling the content of a cyclic carbonyl compound having a carbon atom number of 5 or 6 in the raw material diol to fall in a prescribed range, the color tone of the polyester is improved.
