海藻资源应用于聚羟基脂肪酸酯生产的研究进展
Research progress of the application of seaweed in polyhydro-xyalkanoate production
摘要
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 con-tinuous 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.关键词
