红藻琼胶多糖微生物降解及意义研究进展

Research progress in biodegradation of the agar from red algae

琼胶是红藻细胞壁的重要成分之一。琼胶的生物降解影响着营养盐再循环、大型海藻群落演替、重金属污染和碳汇等海洋生态过程。此外,琼胶降解产物在水产、农业、医药、保健品和生物能源等领域也具有很大应用潜力。因此,近年来琼胶的生物降解及其生态和应用价值已经成为研究热点。本文针对琼胶降解意义、微生物琼胶酶、琼胶代谢途径等方面的研究进展进行综述,为红藻琼胶多糖生态功能和工业价值的综合利用研究提供理论支撑。

Agar is one of the important components in the cell wall of red algae.The biodegradation of agar affects marine ecological processes,such as nutrient recycling,succession of large seaweed communities, heavy metal pollution, and carbon sequestration. In addition, the degradation products of agar demonstrate great application potential in aquaculture, agriculture, medicine, health products, bioenergy, etc. Therefore, the biodegradation of agar and its ecological and application values have become research hotspots in recent years. This article reviews the research progress in the significance of agar degradation, microbial agarases, and agar metabolic pathways, providing theoretical support for the research on the ecological effects and comprehensive utilization of the agar from red algae.
