摘要:
聚羟基脂肪酸酯(polyhydroxyalkanoate, PHA)是一种可生物降解的高分子聚酯材料, 主要由微生物在一定的胁迫条件下产生, 具有较多的单体结构, 由于其具备良好的生物相容性和生物可降解性, 近年来对其研究逐渐深入, 但由于其生产成本较高导致其在生物塑料行业的应用进展缓慢, 而以废料作为微生物碳源进行生产的方式往往会对环境造成二次污染。近年来大型海藻养殖量逐年上升, 其含有丰富的碳水化合物等生物质资源, 对其资源化利用的研究主要集中于食品、医药、饲料、新能源等领域, 目前仅在海藻饲料和海藻肥领域实现了工业化, 对其资源化利用的方式仍然需要不断地研究创新, 使海藻资源的利用率达到最大, 以创造更多的经济价值。为了引入庞大的海藻资源进行PHA的生产, 降低其生产成本, 促进其在生物塑料行业的应用, 本文综述了PHA近年来在生产工艺研究上的进展情况, 阐明了微藻生物合成PHA及大型海藻作为PHA生产的碳源的可行性, 并评估了海藻资源作为碳源开发的优劣, 为将来黄海绿潮资源的开发利用提供新的思路。

Abstract:
Polyhydroxyalkanoate (PHA), which is a type of biodegradable polymer polyester material, is mainly produced by microorganisms under certain stress conditions and has several monomer structures. Research on PHA has gradually expanded in recent years due to its good biocompatibility and biodegradability. However, the research progress of PHA in the bioplastic industry is slow due to its production cost and production using waste as a microbial carbon source often causes secondary pollution in the environment. Recently, the biomass of seaweed, which is rich in biomass resources such as carbohydrates, has been increasing annually. Research on its resource utilization mostly focuses on food, medicine, feed, new energy, and others, lacking innovation; therefore, only the industrialization of seaweed feed and fertilizer has been realized. The resource utilization method still needs continuous research to maximize the utilization rate of seaweed resources and create additional economic value. This paper aims to introduce vast seaweed resources for PHA production, thereby reducing costs and promoting its development in the bioplastics industry. Furthermore, this paper summarizes the progress of the PHA production technology in recent years, clarifies PHA synthesis via microalgae and the feasibility of macroalgae as a carbon source for PHA production, and evaluates the advantages and disadvantages of seaweed resources as carbon source development, providing a new approach for utilizing green tide resources in the Yellow Sea in the future.
