Jellyfish blooms can represent a significant but largely overlooked source of organic matter (OM), in particular at the local and regional scale. We provide an overview of the current state of knowledge on the bloom-forming jellyfish as sink and source of OM for microorganisms. In particularly, we compare the composition, concentration, and release rates of the OM excreted by living jellyfish with the OM stored within jellyfish biomass, which becomes available to the ocean's interior only once jellyfish decay. We discuss how these two stoichiometrically different jelly-OM pools might influence the dynamics of microbial community and the surrounding ecosystem. We conceptualize routes of jelly-OM in the ocean, focusing on different envisioned fates of detrital jelly-OM. In this conceptual framework, we revise possible interactions between different jelly-OM pools and microbes and highlight major knowledge gaps to be addressed in the future.

水母-微生物相互作用对海洋生物地球化学循环的重要性

水母开花可能是重要的有机物质（OM）来源，但在很大程度上被忽视，特别是在地方和区域范围内。我们概述了形成水华作为微生物的OM和汇的形成水母的知识的现状。特别是，我们比较了活水母排出的OM的成分，浓度和释放速率，以及储存在水母生物质中的OM，只有在水母腐烂后才可在海洋内部使用。我们讨论了这两个化学计量不同的果冻-OM池如何影响微生物群落和周围生态系统的动力学。我们将海洋中果冻OM的路线概念化，重点关注碎石果冻OM的不同预想命运。在这个概念框架中，
