Interactions between microplastics and microorganisms in the environment: Modes of action and influencing factors

Dissolved Organic Matter Promotes the Aging Process of Polystyrene Microplastics under Dark and Ultraviolet Light Conditions: The Crucial Role of Reactive Oxygen Species

“…Due to their durability and low cost, plastics that are widely used in various industries pose a serious threat to the environment after being discarded and, more importantly, can break into smaller plastic fragments via environmental weathering, which causes more potential harm to the environment. − Microplastics (MPs) are defined as plastic particles or fibers with a size of less than 5 mm and have received extensive attention in research due to their widespread presence in the environment. , Plastics that have been widely distributed in the environment for a long time are susceptible to ultraviolet (UV) radiation, oxidation reactions, thermal degradation, and biodegradation and break into MPs of smaller sizes, making the MPs easier to transfer into and enrich the food web, thereby posing a threat to the balance of the ecosystem and human health. − In addition, the environmental behavior of MPs after entering the environment is closely related to their own microscopic interface to a large extent, which is affected by their own surface characteristics and microstructure and is closely related to active substances in the environment. , …”

Thiamine-Mediated Microbial Interaction between Auxotrophic Rhodococcus ruber ZM07 and Prototrophic Cooperators in the Tetrahydrofuran-Degrading Microbial Community H-1

“…Therefore, we considered that energy metabolism in ZM11 was inhibited by exogenous thiamine, leading to the accumulation of propionate and causing side effects on bacterial growth. In microbial communities, mutualism could promote communication between bacterial species to obtain an environmental niche and nutrients ( 47 ); however, the interaction between microorganisms could be changed by environmental factors ( 48 ). Here, exogenous thiamine changed the microbial co-occurrence pattern between strains ZM07 and ZM11.…”

Soil microplastics: we need to pay more attention

“…The microbial community in soil with PEMPs was significantly different from those in the soil without PEMPs [60] . Soil porosity and moisture can also be changed by MPs, thereby affecting the distribution of different microorganisms and even resulting in the destruction of microhabitats and the extinction of some microorganisms [61,62] . MPs in the soil environment may accumulate a lot of organic matter or heavy metal pollutants, such as pesticides and metals, e.g., copper, which might inhibit microbial growth [63] .…”

“…The effect and damage of MPs to plants are also multifaceted, because of the diversity of MPs and the mechanisms of MPs and plants. It can be summarized in two ways: (1) directly changing the physiological and biochemical properties of plants through the roots; and (2) changing the physicochemical properties or biological conditions of the soil to indirectly affect the growth of plants [62,[76][77] . The toxicity of MPs to plants after being absorbed by plants is related to other pollutants bound to MPs, such as organic or heavy metal pollutants [78] .…”
