The PTT building block is consisted of 1,3-propanediol. It replaces PET in the 21 century. That’s the reason why does 1,3-propanediol become more important in these recent years. The purpose of this study were focused on separation and purification of 1,3-propanediol from the fermentation broth produced by Klsebsiella pneumonia. The concentration of 1,3-propanediol achieved was 7.13 g/L. The salting out ability become good follow increasing temperature. So separating 1,3-propanediol by salting out that discussed about effect of one salt and effect of two salts at 60oC. The sodium phosphate tribasic had the highest distribution coefficient of 1,3-propanediol was 3.722 and the recovery of 1,3-propanediol was 72% in signal-salt system. The highest distribution coefficient of 1,3-propanediol for using sodium phosphate tribasic and sodium sulfate was 2.52 and the recovery of them were...
