在过去的二十年里，许多报告显示存在能够杀死浮游植物的细菌。这些溶藻细菌的丰度有时会随着藻华的减少而增加，这表明它们可能会影响藻华的动态。在这里，我们综合现有的知识溶藻细菌与海洋真核微藻的相互作用。我们讨论了目前的方法来表征溶藻表型在生态系统中的有效性。我们简要地考虑了文献上的系统发育鉴定的溶藻细菌，它们与藻类猎物的相互作用，溶藻分子的表征，并在藻华的溶藻细菌的计数。我们的结论是，由于目前的方法的局限性，溶藻细菌引起水华下降的证据是间接的。需要新的方法和生态系统的方法来测试假设的影响，溶藻细菌在藻华动力学。这将需要扩大调查范围，目前的重点是溶藻细菌在控制有害藻华方面的潜在用途。我们建议在海洋中藻类群落结构的细菌调节的一般问题内概念化细菌] algicidy。
Over the past two decades, many reports have revealed the existence of bacteria capable of killing phytoplankton. These algicidal bacteria sometimes increase in abundance concurrently with the decline of algal blooms, suggesting that they may affect algal bloom dynamics. Here, we synthesize the existing knowledge on algicidal bacteria interactions with marine eukaryotic microalgae. We discuss the effectiveness of the current methods to characterize the algicidal phenotype in an ecosystem context. We briefly consider the literature on the phylogenetic identification of algicidal bacteria, their interaction with their algal prey, the characterization of algicidal molecules, and the enumeration of algicidal bacteria during algal blooms. We conclude that, due to limitations of current methods, the evidence for algicidal bacteria causing algal bloom decline is circumstantial. New methods and an ecosystem approach are needed to test hypotheses on the impact of algicidal bacteria in algal bloom dynamics. This will require enlarging the scope of inquiry from its current focus on the potential utility of algicidal bacteria in the control of harmful algal blooms. We suggest conceptualizing bacteria] algicidy within the general problem of bacterial regulation of algal community structure in the ocean.
