BIOMOLECULES AND ENZYMES

Detailed explanation-1: -Enzyme recycle is required to lower the cost of the enzymes, while the reuse of the spent cellulose will lower the feedstock cost.

Detailed explanation-2: -Enzymatic Depolymerization as a Solution These biological processes usually work by placing plastic waste in a bioreactor with specific enzymes such as PETase and MHETase that bind specifically to the PET polymers and monomers to depolymerize the long PET polymer chains.

Detailed explanation-3: -This PETase enzyme breaks down a commonly used plastic-called PET, or polyethylene terephthalate-into its component parts, which can then be reassembled into shiny new plastic. In order for enzymatic degradation of PET to be commercially viable, researchers needed to develop a faster version of PETase.

Detailed explanation-4: -Enzymes are reusable. Once an enzyme binds to a substrate and catalyzes the reaction, the enzyme is released, unchanged, and can be used for another reaction. This means that for each reaction, there does not need to be a 1:1 ratio between enzyme and substrate molecules.
