Mismanaged plastics, upon entering the environment, undergo degradation through physicochemical and/or biological processes. This process often results in formation of microplastics (MPs), most prevalent form plastic debris (<1 mm). MPs pose severe threats to aquatic and terrestrial ecosystems, necessitating innovative strategies for effective remediation. Some photosynthetic microorganisms can degrade but there lacks a comprehensive review. Here we examine specific role photoautotrophic water soil environments biodegradation focussing on their unique ability grow persistently diverse polymers under sunlight. Notably, these cells utilise light CO2 produce valuable compounds such as carbohydrates, lipids, proteins, showcasing multifaceted environmental benefits. We address key scientific questions surrounding utilisation nanoplastics (NPs) bioremediation, discussing potential engineering enhanced efficacy. Our review highlights significance alternative biomaterials exploration strains expressing enzymes, polyethylene terephthalate (PET) hydrolases, conjunction with microalgal cyanobacterial metabolisms. Furthermore, delve into promising photo-biocatalytic approaches, emphasising coupling sunlight exposure. The integration microalgal-bacterial consortia is explored biotechnological applications against NPs pollution, synergistic effects wastewater treatment absorption nitrogen, heavy metals, phosphorous, carbon. In conclusion, this provides overview current state research use bioremediation. It underscores need continued investigation development approaches tackle global issue pollution ecosystems.

Abstract This study exploited the different combinations of nutritional modes (autotrophic, mixotrophic and heterotrophic) green alga Scenedesmus obliquus in a two-stage cultivation process to remediate wastes as well maximise production high-protein algal biomass. The was first cultivated autotrophically Stage-one, using 0.5% digestate nutrient source natural light support growth; afterward, culture concentrated used Stage-two under modes. 2.5% anaerobic from food waste provide inorganic nutrients; sugar recovered confectionery manufacturer organic carbon mixo- hetero-trophic growth. In algae removed ammonium phosphate at 9.1 mg L −1 day 3.8 , respectively, yield approached carrying capacity 1 g dry weight per liter. Stage-two, population increased faster heterotrophic modes, reaching final concentration 7.2–10.5 than autotrophic mode. Ammonium were consumed about twice rate mode, 90–100% within 48–72 h. biomass had protein content 44% compared only 32% demonstrated that coupling growth S. can be both boost protein-rich biomass, which beneficial sustainable circular bioeconomy.
