Biodegradation of polystyrene and systems biology-based approaches to the development of new biocatalysts for plastic degradation
Plastic waste has become one of the most pressing environmental issues with rapidly increased their production that also has a severe impact on individual species and ecosystem functioning.
With recycling technologies in place, the waste plastic will become a valuable resource and hence less material will be lost to the environment. In the pursuit of a sustainable approach to the treatment of plastic waste, biological processes have emerged as an eco-friendly method with significant potential. In this review, we summarize previous research on the biodegradation of polystyrene (PS) as major plastics, including a review of the analytical methods used to investigate the plastic biodegradation, the isolation of PS-degrading microbes from various environment, and the identification of potential enzymes for PS biodegradation. Based on this, we propose a potential PS biodegradation pathway, even though the specific biochemical mechanisms associated with certain enzymes have not yet been fully identified. Finally, we discuss how PS-biodegrading enzymes can be identified using a systems biology-based screening approach that combines culture-based genomic and culture-independent metagenomic methods. This strategy can be applied to searching biodegrading enzymes for other plastics.
期刊介绍:
Current Opinion in Systems Biology is a new systematic review journal that aims to provide specialists with a unique and educational platform to keep up-to-date with the expanding volume of information published in the field of Systems Biology. It publishes polished, concise and timely systematic reviews and opinion articles. In addition to describing recent trends, the authors are encouraged to give their subjective opinion on the topics discussed. As this is such a broad discipline, we have determined themed sections each of which is reviewed once a year. The following areas will be covered by Current Opinion in Systems Biology: -Genomics and Epigenomics -Gene Regulation -Metabolic Networks -Cancer and Systemic Diseases -Mathematical Modelling -Big Data Acquisition and Analysis -Systems Pharmacology and Physiology -Synthetic Biology -Stem Cells, Development, and Differentiation -Systems Biology of Mold Organisms -Systems Immunology and Host-Pathogen Interaction -Systems Ecology and Evolution
