    摘要: Industrial-scale fermentative production of 3-carboxy-cis,cis-muconic acid from terephthalic acid. Also, a protocatechuate 4,5-ring-cleaving enzyme gene-disrupted strain in which the gene coding for (a) the amino acid sequence set forth in SEQ ID NO: 1 or 3, or (b) the amino acid sequence set forth in SEQ ID NO: 1 or 3 which has a deletion, substitution, addition and/or insertion of one or more amino acids and exhibits protocatechuate 4,5-ring cleavage activity, present in the chromosomal DNA of microbial cells, has been disrupted; recombinant plasmids comprising the Tph gene and protocatechuate 3,4-dioxygenase gene; transformants obtained by introducing the recombinant plasmids into the disrupted strain; and a process for production of 3-carboxy-cis,cis-muconic acid and/or 3-carboxymuconolactone characterized by culturing the transformants in the presence of terephthalic acid.
