Microplastic Accumulation and Degradation in Environment via Biotechnological Approaches
AI summary Read the abstract
This review examines how biotechnological approaches, including genetic engineering, genome editing, and synthetic biology, can enhance microbial degradation of plastics. Researchers found that while microplastics and nanoplastics are now found throughout the environment and even in food and the human body, improved methods for plastic biodegradation could help reduce their production. The study highlights the potential of engineered microorganisms as a strategy for addressing plastic waste accumulation.
The extensive use of plastics in daily life has led to the generation of huge amounts of plastic waste, which causes an enormous burden on the environment. More than half of the plastic waste ends up in the landfill, and about one-fifth of waste is managed by incineration. Only about one-tenth of plastic waste is recycled, and the rest, about one-fifth of mismanaged plastic waste, ends up in the terrestrial and aquatic environment. Here, we review how the deterioration of plastics leads to the formation of microplastics and nanoplastics, which are now found abundantly and are contaminating aquatic life and water bodies. It observed that increasing experimental evidence provides data about the presence of these microplastics in food items, terrestrial environment, and even the human body. The harmful effects of microplastics on human health still need to be substantiated with more precise experimental studies. However, measures can be taken to reduce the production of microplastics by improving the methods used for plastic degradation. This review focuses on the use of genetic engineering, genome editing, synthetic biology, and system biology approaches to increase the potential of microorganisms to degrade plastics.
