Enhancing the activity of a plastic-degrading enzyme

Enhancing the activity of a plastic-degrading enzyme, a biofilm-producing micro-organism is modified to exhibit elevated levels of cyclic di-GMP. The enzyme can be a PETase. The micro organism, such as E. coli, can be modified to express a heterologous diguanylate cyclase such as DdcC or WspR. An expression construct for use in the method encodes an enzyme that modulates levels of cyclic di-GMP, such as diguanylate cyclase, and also a plastic degrading enzyme, such as a PETase. The diguanylate cyclase can be an E. coli diguanylate cyclase or a P. aeruginosa diguanylate cyclase.

Abstract

Enhancing the activity of a plastic-degrading enzyme, a biofilm-producing micro-organism is modified to exhibit elevated levels of cyclic di-GMP. The enzyme can be a PETase. The micro organism, such as E. coli, can be modified to express a heterologous diguanylate cyclase such as DdcC or WspR. An expression construct for use in the method encodes an enzyme that modulates levels of cyclic di-GMP, such as diguanylate cyclase, and also a plastic degrading enzyme, such as a PETase. The diguanylate cyclase can be an E. coli diguanylate cyclase or a P. aeruginosa diguanylate cyclase.
