초록

For the production of cis, cis-muconic acid via biocatalytic conversion reactions from a toxic cosubstrate, benzoic acid, a fed-batch process using computer-controlled DO-stat feeding was developed. The mutant strain of Pseudomonas putida BM014 produced cis, cis-muconic acid from benzoic acid with high conversion yield. More than 32 g/L of cis, cis-muconic acid was accumulated in 42h and a productivity of 1.4g/(L.h)was achieved.
