Interaction of Micro- and Nanoplastics with Enzymes: The Case of Carbonic Anhydrase

International Journal of Molecular Sciences, Journal Year: 2024, Volume and Issue: 25(17), P. 9716 - 9716

Published: Sept. 8, 2024

Microplastics (MPs) and nanoplastics (NPs) have emerged as significant environmental pollutants with potential detrimental effects on ecosystems human health. Several studies indicate their interaction enzymes; this topic represents a multifaceted research field encompassing several areas of interest from the toxicological ecotoxicological impact MPs NPs humans wildlife to biodegradation plastics by microbial enzymes. This review aims provide critical analysis state-of-the-art knowledge enzyme carbonic anhydrase (CA), providing recent insights, analyzing gaps in field, drawing future perspectives its application. CA is widespread crucial various organisms; it for physiological processes animals, plants, bacteria. It catalyzes reversible hydration CO2, which essential respiration, acid–base balance, pH homeostasis, ion transport, calcification, photosynthesis. Studies demonstrate that can inhibit activity mechanisms including adsorption surface subsequent conformational changes. In vitro silico highlight role electrostatic hydrophobic interactions these processes. vivo present mixed results, are influenced factors like particle type, size, concentration, organism type. Moreover, potentiality esterase plastic degradation discussed. The complexity between MPs/NPs underscores need further fully understand ecological health impacts expression glimpses field.

Effects of Polystyrene Microparticles on Growth and Physiological Metabolism of Microalgae Scendesmus obliquus

Sustainability, Journal Year: 2023, Volume and Issue: 15(14), P. 11223 - 11223

Plastic products are widely used due to their lightness, durability, low cost, and malleability, threat the environment is becoming increasingly apparent. However, detailed mechanism of such an effect unclear. Due improper treatment, microplastic contamination very much studied in areas around sewage outfalls or some plastic manufacturers, its content high. To investigate ecological impact microplastics this particular area, we evaluated toxic polystyrene (PS-MPs) on microalgae Scenedesmus obliquus (S. obliquus). In particular, cell growth, photosynthesis, antioxidant enzyme activity, membrane permeability, morphology presence different PS-MP concentrations were monitored. These new data revealed increase growth as early response low-dose exposure with a maximum inhabitation rate −3.33%. contrast, higher concentration solution leads significant inhibition within test concentration, 43.62%. Meanwhile, decreased photosynthesis activity S. was observed during exposure. Moreover, PS-MPs induced oxidative damage algae cells, exhibiting activities enhanced lipid peroxidation reactions, evidenced by reduction superoxide dismutase (SOD) level increased malondialdehyde (MDA) content, well damaged soluble protein. Collectively, our study systematically investigates toxicity microalgae, providing deep insight into possible influences pollution whole food web aquatic ecosystem.
