| 摘 要： | β-二甲基巯基丙酸内盐(DMSP)是一种在海洋中普遍存在的重要生源有机硫化物,其降解产物二甲基硫(DMS)挥发到大气中会形成云凝结核,进而对大气温度产生负反馈效应.DMSP主要由浮游植物和部分细菌生物合成,在浮游食物链和微食物环中进行传递和转化,并进一步通过食物网进入更高营养级.浮游生物是驱动全球碳、硫循环的关键环节,...

| Abstract: | Dimethylsulfoniopropionate(DMSP)is an important biogenic organic sulfide that is ubiquitous in the ocean.Dimethylsulfide(DMS),the degradation product of DMSP,volatilizes into the atmosphere to form cloud condensation nuclei which has a negative effect on atmospheric temperature.DMSP is mainly biosynthesized by phytoplankton and some bacteria,and is transferred and transformed in the planktonic food chain and microbial food loop,and then enters into the higher trophic level through the food web.Plankton is a key link driving the global carbon and sulfur cycling,and its role in the DMSP biogeochemical cycling has received increasing attention.We reviewed the sources,sinks,and transfer of DMSP in the planktonic food chain.We also introduced the role of the planktonic food chain and microbial food loop in the transfer and transformation of DMSP.There are still many research gaps about the transmission and degradation pathways of DMSP in the marine food chain.In the future,further attention should be focused on the mechanisms of generation,transmission and conversion mechanisms of DMSP,which is crucial to a better understanding of the biogeochemical cycling of DMSP. |
