Research efforts have shifted to creating biodegradable polymers to offset the harmful environmental impacts associated with the accumulation of non-degradable synthetic polymers in the environment. This review presents a comprehensive examination of the role of green microbes in fostering sustainable bioproduction of these environment-friendly polymers. Green microbes, primarily algae and cyanobacteria, have emerged as promising bio-factories due to their ability to capture carbon dioxide and utilize solar energy efficiently. It further discusses the metabolic pathways harnessed for the synthesis of biopolymers such as polyhydroxyalkanoates (PHAs) and the potential for genetic engineering to augment their production yields. Additionally, the techno-economic feasibility of using green microbes, challenges associated with the up-scaling of biopolymer production, and potential solutions are elaborated upon. With the twin goals of environmental protection and economic viability, green microbes pave the way for a sustainable polymer industry.
研究工作已转向开发可生物降解的聚合物，以抵消环境中不可降解合成聚合物积累所带来的有害环境影响。本综述全面考察了绿色微生物在促进这些环保聚合物可持续生物生产中的作用。绿色微生物，主要是藻类和蓝细菌，由于其能够捕获二氧化碳并高效利用太阳能，已成为有前景的生物工厂。它还讨论了用于合成聚羟基脂肪酸酯（PHA）等生物聚合物的代谢途径，以及基因工程提高其产量的潜力。此外，还阐述了使用绿色微生物的技术经济可行性、生物聚合物生产扩大规模所面临的挑战以及潜在的解决方案。出于环境保护和经济可行性的双重目标，绿色微生物为可持续聚合物产业铺平了道路。
