The impact of microplastic-microbe interactions on animal health and biogeochemical cycles: A mini-review
Summary
This review examines the two-way interactions between microplastics and microorganisms in the environment. Researchers found that microplastics provide surfaces for bacteria to colonize and form biofilms, while some microbes can physically break down the plastics over time. The study highlights how these microplastic-microbe combinations can disrupt gut bacteria in animals and may affect broader biogeochemical cycles like carbon and nitrogen cycling.
Microplastic (MP) pollution has attracted global attention due to the extensive use of plastic products. The hydrophobic MP surface provides a habitat for multiple microorganisms. Although there have been several studies on the impact of plastic particles on microbial communities, there are few reviews that have systematically summarized the interaction between MPs and microbes and their effects on human health and biochemical circulation. The discussions in this review will take place under the following topics: (1) MPs prompt colonization, biofilm generation, and transfer of environmental microbes; (2) the microbial communities can cause the morphological alterations and biodegradation of MPs; (3) MP-microbe combinations can induce the alteration of intestinal flora and hazard animal health; (4) the biogeochemical cycles affected by MP-microbe interactions. This review will highlight the close interactions between MPs and microorganisms, and provide suggestions for future studies.
