产1,3-丙二醇菌株的筛选、改良及发酵

Screening, Modification and Fermentation of Strains Producing 1,3-Propanediol

摘要:

从自然界筛选得到了9株可发酵甘油生产1,3 丙二醇的肠道细菌,经鉴定均为肺炎克雷伯氏菌.经化学诱变,菌株的1,3 丙二醇产量有所提高,其最终产量达到2%左右.

Abstract:

Nine strains of enteric bacteria,capable of converting glycerol to 1,3-PD were screened. All of the strains were identified as Klebsiella pneumoniae. After chemical mutation, the prodution of 1,3-PD was improved. After beering optimized the fermentation t
