摘　　要：甘氨酸甜菜碱(GBT)是海洋藻类中广泛存在的一种含氮渗透调节物质,其被降解后产生的有机胺可通过海气交换进入大气中。近年研究表明,大气中有机胺可以促进新粒子生成及增长,具有潜在重要的气候效应,因此,海洋环境中有机胺的形成机制越来越受到关注。概述了海洋藻类中GBT合成及其降解为有机胺的途径,归纳了不同藻类体内GBT的浓度分布特征,探讨了影响藻类体内GBT浓度的因素,剖析了该领域待解决的科学问题,并对今后的研究工作进行了展望,以期为提高对海洋环境中有机胺来源的认识提供科学参考。Glycine betaine(GBT)is a nitrogen containing osmotic adjustment substance widely found in marine algae.The organic amines produced after degradation can enter the atmosphere through sea air exchange.Recent studies have shown that organic amines in the atmosphere can promote the generation and growth of new particles,and have potentially important climate effects.Therefore,the formation mechanism of organic amines in the marine environment has attracted more and more attention.This article outlined the pathways of GBT synthesis and degradation into organic amines in marine algae,summarized the distribution characteristics of GBT in different algae,discussed the factors that affect the concentration of GBT in algae,and analyzed the scientific problems to be solved in this field.The future research work is prospected,hoping to provide a scientific reference for improving the understanding of the sources of organic amines in the marine environment.
