Microplastic stress induce bioresource production and response in microalgae: a concise review
AI summary Read the abstract
This review examines how microplastic stress influences bioresource production in microalgae, covering the pathways by which exposure to microplastics induces oxidative stress responses including lipid accumulation and antioxidant enzyme production. Researchers found that microplastic-induced stress can paradoxically enhance production of industrially and pharmaceutically valuable compounds while also stimulating microplastic removal capacity in aquatic ecosystems.
There are many literatures on the importance of bioresources from microalgae, but this review shows how microalgae are able to respond to the stress induced by microplastics (MP) and how the process leads to the production of bioresources. The study of these bioresources is significant because they are harnessed by man as energy and pharmaceutical tools. The extent of MP in the aquatic environment, microalgae stress induced by MP, the response of microalgae to stress induced by MP and bioresource production in microalgae due to stress induced by MP are described. The study shows that the presence of MP in the environment can induce nutrients and environmental stress, which enhances lipid accumulation and the production of other useful biotechnology resources. The study also shows that microalgae tend to produce resources that can respond to the stress induced by MP, which leads to a high removal efficiency of MP in aquatic ecosystems. The study also shows that the production of bioresources in the form of antioxidants, which are either enzymatic or non-enzymatic antioxidants, is the basic reason why microalgae are able to remove MP. A number of studies have shown the effect of MP on microalgae, while others have shown the efficiency of microalgae in the removal of MP from aquatic systems. But scanty literature exists showing how MP induces stress on microalgae. More studies are needed to show the mechanism and the concentration of bioresources produced by microalgae under the stress of MP.

Lipid fluorescence and antioxidant activity in microalgae under polystyrene microplastic stress
AI summary Read the abstract
Tiny plastic particles (microplastics) can stress out microalgae, the base of the ocean food chain, causing them to temporarily disrupt their fat production and ramp up antioxidant defenses to cope with the damage. Since these microalgae are eaten by small fish and other creatures that eventually end up in our food supply, this stress response could ripple up the food chain, potentially affecting the nutritional quality of seafood we eat. While this study didn't test human health directly, it adds to growing evidence that microplastic pollution may quietly reshape the marine ecosystems we depend on for food.
Evaluating physiological responses of microalgae towards environmentally coexisting microplastics: A meta-analysis
AI summary Read the abstract
A meta-analysis of 52 studies found that microplastics inhibit microalgal growth and photosynthesis and induce oxidative damage, though microalgae can recover over time. Cyanobacteria are more vulnerable than green algae, and the relative size of microplastics to algal cells governs the mechanism of impact, while aged versus pristine microplastics have opposite effects on extracellular polymeric substance and microcystin production.
