Plastic debris in the environment is degraded in nature by photo-, bio-, and thermo-oxidative depolymerization as well as friction (Barnes et al., 2009; Browne et al., 2011). Chem. Biodegradation of Polycaprolactone (PCL) blended PP has also been demonstrated using lipase since lipase is well known to degrade the ester linkages of PCL (Weiland et al., 1995). (2004). Int. Research focusing on digestive enzyme(s) in plastic-degrading invertebrates and their gut microbes could also lead to novel approach for plastic degradation, especially for persistent non-hydrolyzable polymers.

Purification and characterization of a soluble polyurethane degrading enzyme from Comamonas acidovorans. Structural variations in PE polymers formed during polymerization and subsequent processing, such as unsaturated carboncarbon double bonds, carbonyl groups, and hydroperoxide groups (Ojeda et al., 2011) have been shown to be consumed first by the bacteria resulting in rapid growth. Health 16:1941. doi: 10.3390/ijerph16111941, Restrepo-Flrez, J.-M., Bassi, A., and Thompson, M. R. (2014). This branching system makes LDPE chains more accessible and the tertiary carbon atoms at the branch sites more susceptible to attack. There are many different types of esterase, which differ in their protein structure, substrate specificity, and biological functions. Recent studies have shown that the digestive tracts (gut) of some insects function as bioreactors, with digestive enzymes and gut microbiomes that appear to contribute to and accelerate the biodegradation rate of some recalcitrant plastics. *Correspondence: David B.
