MAJOR APPLICATIONS Potential applications involve oxygen enrichment apphcable to combustion furnaces, car engines, and respiration-aiding apparatuses. Also in the transport of oxygen dissolved in water applied to contact lenses and artificial lungs. In liquid mixture separation associated with ethanol concentration of fermented biomass. Furthermore, in polymer degradation related to resist materials for microlithography. [Pg.863]

Presently enzymes can hardly be used to degrade artificial synthetic polymers unless it is under special conditions. It is worth noting that compounds like poly(vinyl alcohol), PVA, bacterial polymers and poly(e-caprolatone), PCL, that are biodegradable under outdoor conditions are degraded abiotically and thus very slowly in an animal body where they are not biodegradable. Despite this difficulty the number of artificial polymers proposed as biodegradable biomaterial candidates to replace biopolymers or biostable polymers is increasing. [Pg.69]

Sericin is recovered during the various stages of producing raw silk. Sericin is oxidation-, bacterial-, and UV-resistant, and it absorbs and releases moisture rapidly. Sericin can be cross-linked, copolymerized, and blended with other macromolecular materials, especially artificial polymers. The materials modified with sericin and sericin composites are useful as degradable biomaterials, biomedical materials, polymers, functional membranes, fibers, and fabrics [26]. [Pg.488]
