In a method of enhancing the activity of a plastic-degrading enzyme (32) such as a PETase, a biofilm-producing micro-organism (30) is modified to exhibit elevated levels of cyclic di-GMP. The micro- organism (30), such as E. coli modified to express and secrete the plastic-degrading enzyme (32), 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 (32), such as a PETase. The diguanylate cyclase can be an E. coli diguanylate cyclase or a P. aeruginosa diguanylate cyclase. A biofilm-forming micro-organism (30) is transformed by the expression construct.

This invention relates to an apparatus (high shear device) and method for treating liquid metals by intensive melt shearing. The apparatus comprises a stator and a rotor with a small gap between them to provide intensive melt shearing for dispersing efficiently and distributing uniformly gas, liquid and solid phases in liquid metals without severe turbulence at the melt surface. The device can be extended to a multistage high shear pump by arranging individual rotor/stator assemblies either concentrically (one in another) or vertically. The device and high shear pump can be readily integrated into existing casting processes. The device is suitable for use in casting processes including high pressure die casting, low pressure die casting, gravity die casting, sand casting, investment casting, direct chill casting, twin roll casting, and any other casting process which requires liquid metal as a feedstock. In addition, the device is particularly suitable for providing conditioned liquid metal for both shape casting and continuous (or semi-continuous) casting of metallic materials, preparing high quality semi-solid slurries, solidification processing of particulate reinforced metal matrix composites, mixing immiscible metallic liquids and degassing of liquid metals prior to any casting processes.
