Microbial Degradation for Microplastic Remediation: Mechanisms and Analysis
AI summary Read the abstract
This paper reviews existing research on how bacteria, fungi and archaea, including species like Pseudomonas and Ideonella sakaiensis, break down microplastics using enzymes. It also discusses how factors like temperature and nutrients affect this process, and notes that degradation remains slow, requiring further engineering work.
Microbial degradation presents an eco-friendly and sustainable approach to addressing microplastic (MP) pollution. This section explores the role of microorganisms, including bacteria, fungi, and archaea, in breaking down synthetic polymers through enzymatic actions such as oxygenases, esterases, and hydrolases. Key species like Pseudomonas, Ideonella sakaiensis, Aspergillus, and Rhodococcus are emphasized. The impact of environmental factors, including temperature, salinity, and nutrient levels, on degradation efficiency is discussed. Additionally, advanced analytical tools like FTIR, Raman spectroscopy, and SEM aid in assessing polymer breakdown. Overcoming challenges like slow degradation rates requires innovative bioengineering strategies for effective MP bioremediation.

Recent advances in biodegradation of emerging contaminants - microplastics (MPs): Feasibility, mechanism, and future prospects
AI summary Read the abstract
This review explores biological approaches to breaking down microplastics, including using bacteria, fungi, and enzymes. While some organisms can partially degrade certain plastic types, the process is slow and incomplete compared to the scale of pollution. The research is promising for future cleanup efforts but shows that biodegradation alone cannot yet solve the microplastic contamination problem.
