Method for producing glycolic acid by immobilization

Abstract

The present invention provides a method for producing glycolic acid by immobilization. The method for producing glycolic acid by immobilization includes providing a modified strain, the modified strain includes the gene sequences of SEQ ID NO: 1, SEQ ID NO: 2 and SEQ ID NO: 3, and producing polyvinyl alcohol bacteria particles, said The polyvinyl alcohol bacteria pellet includes the modified strain; and a carbon source is supplied to the polyvinyl alcohol bacteria pellet to convert the carbon source into glycolic acid using the modified strain. The polyvinyl alcohol bacteria pellets are mixed with the auxiliary solution, and the carbon source is supplied to the polyvinyl alcohol bacteria pellets and air is introduced at the same time.
