| 摘 要：以熱帶假絲酵母(Candidatropicalis)為菌種發(fā)酵生產(chǎn)1,13 十三碳二羧酸(DCl3)是現階段最經(jīng)濟的方法。通過(guò)對接種量、補堿工藝、發(fā)酵級數和空氣流量的優(yōu)化以及采取中間補加正十三碳烷烴(C13)、延長(cháng)發(fā)酵周期等措施,確定了最佳的DC13發(fā)酵工藝,15m3發(fā)酵DC13的產(chǎn)量達到850kg,主要原材料正十三碳烷烴的消耗下降了11 6%。 |

| Abstract：It is an economic method to produce tridecanedioic acid by the fermentation of candida tropicalis in recent time. In this paper, the optimized fermentation conditions were obtained by investigating seed concentration, alkali supplementation,fermentative grade and aeration volume. The method of alkane supplementation and prolonging fermentation time was also adopted. The yield in 15m~3 fermentation tank reached 850kg and the major cost of material was reduced 11.6%. |
| Key words：candida tropicalis; tridecanedioic acid; fermentation |
