Plastics degradation by hydrolytic enzymes: The plastics‐active enzymes database—PAZy

Proteins Structure Function and Bioinformatics, Journal Year: 2022, Volume and Issue: 90(7), P. 1443 - 1456

Petroleum-based plastics are durable and accumulate in all ecological niches. Knowledge on enzymatic degradation is sparse. Today, less than 50 verified plastics-active enzymes known. First examples of acting the polymers polyethylene terephthalate (PET) polyurethane (PUR) have been reported together with a detailed biochemical structural description. Furthermore, very few polyamide (PA) oligomer active In this article, current known synthetic PET PUR briefly summarized, their published activity data were collected integrated into comprehensive open access database. The Plastics-Active Enzymes Database (PAZy) represents an inventory experimentally that act fossil fuel-based polymers. Almost 3000 homologs PET-active identified by profile hidden Markov models. Over 2000 PUR-active BLAST. Based multiple sequence alignments, conservation analysis most conserved amino acids, motifs for PET- derived.

Microplastics waste in environment: A perspective on recycling issues from PPE kits and face masks during the COVID-19 pandemic

Environmental Technology & Innovation, Journal Year: 2022, Volume and Issue: 26, P. 102290 - 102290

During the COVID-19 pandemic, extensive use of face masks and protective personal equipment (PPE) kits has led to increasing degree microplastic pollution (MP) because they are typically discarded into seas, rivers, streets, other parts environment. Currently, a negative impact on environment high-level fragmentation. Typically, MP can be detected by various techniques, such as microscopic analysis, density separation, Fourier transform infrared spectrometry. However, there limited studies disposable PPE kits. A wide range marine species ingest MPs in form fibers fragments, which directly affect human health; thus, more research development needed effect health. This article provides perspective origin distribution waterbodies (e.g., ponds, lakes, seas) wastewater treatment plants, reviews possible remediation related excessive disposal aquatic environments.
