Abstract
Microplastics (MPs) degrade through various abiotic processes (thermal, mechanical, hydrolytic, and photo-oxidative) and biotic processes involving microorganisms. This study investigates specific bacteria, fungi, and algae that contribute to MP biodegradation, focusing on species like Bacillus, Rhodococcus, and Pseudomonas, which produce enzymes such as PETase, laccases, and peroxidases to break down high- and low-density polyethylene. However, the biodegradation process varies based on environmental factors and the durability of plastics. There is an urgent need to use advanced methods to understand degradation and its byproducts. Microbial degradation holds promise for addressing MPs, but further research is needed to enhance efficiency and develop sustainable solutions.
期刊介绍：
Current Opinion in Chemical Engineering is devoted to bringing forth short and focused review articles written by experts on current advances in different areas of chemical engineering. Only invited review articles will be published.
The goals of each review article in Current Opinion in Chemical Engineering are:
1. To acquaint the reader/researcher with the most important recent papers in the given topic.
2. To provide the reader with the views/opinions of the expert in each topic.
The reviews are short (about 2500 words or 5-10 printed pages with figures) and serve as an invaluable source of information for researchers, teachers, professionals and students. The reviews also aim to stimulate exchange of ideas among experts.
Themed sections:
Each review will focus on particular aspects of one of the following themed sections of chemical engineering:
1. Nanotechnology
2. Energy and environmental engineering
3. Biotechnology and bioprocess engineering
4. Biological engineering (covering tissue engineering, regenerative medicine, drug delivery)
5. Separation engineering (covering membrane technologies, adsorbents, desalination, distillation etc.)
6. Materials engineering (covering biomaterials, inorganic especially ceramic materials, nanostructured materials).
7. Process systems engineering
8. Reaction engineering and catalysis.
