3. The study of PVA biodegradation mechanism There are three main types of PVA degrading enzymes, namely PVA oxidase, PVA dehydrogenase, and oxidative PVA hydrolase. The catalytic reaction mechanism of these three types of enzymes will be explored below. The degradation of PVA by enzymes is a comple Read More

2. PVA degradase In the practical application of biodegradation of polyvinyl alcohol, enzymes tend to be easier to use industrially than microbial formulations, and their results tend to be better. This is mainly due to the PVA degradation microorganisms in the process of degradation of polyvinyl al Read More

Polyvinyl alcohol (PVA) is a synthetic polymer compound, which is widely used in textile and paper industries. It is easily soluble in water but difficult to degrade under natural conditions, and is a difficult pollutant to degrade in water treatment. Its content in textile wastewater is very high, Read More
