STRUCTURAL GENE OF CELL MEMBRANE BONDING TYPE ALDEHYDE DEHYDROGENASE, PLASMID CONTAINING THE SAME, TRANSFORMED ACETIC ACID BACTERIUM AND METHOD FOR FERMENTING ACETIC ACID

摘要

PURPOSE:To enhance content of an enzyme in a cell as well as efficiency of fermentation and enable efficient production of a desired acid by isolating a structural gene of cell membrane bonding type aldehyde dehydrogenase and integrating the isolated gene into a plasmid. CONSTITUTION:A microorganism belonging to the genus Acetobacter or Gluconobacter is transformed by a plasmid containing a structural gene of a cell membrane bonding type aldehyde dehydrogenase derived in a microorganism of the genus Acetobacter and having about 3.6 kilo base molecular size and fermentation is carried out using the transformed microorganism to provide the acid, especially acetic acid. The map of restriction enzyme of the structural gene is shown in the figure.
