  • TRANSFORMED STRAIN AND METHOD FOR DEGRADING PET BY USING THE SAME
    Publication number: 20250145940
    Abstract: The present invention provides a transformed strain, comprising: a host cell; a first nucleotide sequence, located inside the host cell, the first nucleotide sequence encoding a PETase, which is derived from Ideonella; and a second nucleotide sequence, located inside the host cell, the second nucleotide sequence comprising a first chaperon nucleotide sequence or a second chaperon nucleotide sequence; wherein the first chaperon nucleotide sequence encodes a molecular chaperon protein (GroELS), and the second chaperon nucleotide sequence encodes a lipase secretion chaperone protein (LsC). The present invention also provides a method for degrading plastic, using said transformed strain for degrading a plastic having PET.
