摘　　要：Mismanaged plastics,upon entering the environment,undergo degradation through physicochemical and/or biological processes.This process often results in the formation of microplastics(MPs),the most prevalent form of plastic debris(<1 mm).MPs pose severe threats to aquatic and terrestrial ecosystems,necessitating innovative strategies for effective remediation.Some photosynthetic microorganisms can degrade MPs but there lacks a comprehensive review.Here we examine the specific role of photoautotrophic microorganisms in water and soil environments for the biodegradation of plastics,focussing on their unique ability to grow persistently on diverse polymers under sunlight.Notably,these cells utilise light and CO_(2) to produce valuable compounds such as carbohydrates,lipids,and proteins,showcasing their multifaceted environmental benefits.We address key scientific questions surrounding the utilisation of photosynthetic microorganisms for MPs and nanoplastics(NPs)bioremediation,discussing potential engineering strategies for enhanced efficacy.Our review highlights the significance of alternative biomaterials and the exploration of strains expressing enzymes,such as polyethylene terephthalate(PET)hydrolases,in conjunction with microalgal and/or cyanobacterial metabolisms.Furthermore,we delve into the promising potential of photo-biocatalytic approaches,emphasising the coupling of plastic debris degradation with sunlight exposure.The integration of microalgal-bacterial consortia is explored for biotechnological applications against MPs and NPs pollution,showcasing the synergistic effects in wastewater treatment through the absorption of nitrogen,heavy metals,phosphorous,and carbon.In conclusion,this review provides a comprehensive overview of the current state of research on the use of photoautotrophic cells for plastic bioremediation.It underscores the need for continued investigation into the engineering of these microorganisms and the development of innovative approaches to tackle the global issue of plastic pollution
