Abstract

Until recently, the data on the diversity of the entire microbial community from the Baltic Sea were relatively rare and very scarce. However, modern molecular methods have provided new insights into this field with interesting results. They can be summarized as follows. (i) Although low salinity causes a reduction in the biodiversity of multicellular species relative to the populations of the North-East Atlantic, no such reduction occurs in bacterial diversity. (ii) Among cyanobacteria, the picocyanobacterial group dominates when considering gene abundance, while filamentous cyanobacteria dominate in means of biomass. (iii) The diversity of diatoms and dinoflagellates is significantly larger than described a few decades ago; however, molecular studies on these groups are still scarce. (iv) Knowledge gaps in other protistan communities are evident. (v) Salinity is the main limiting parameter of pelagic fungal community composition, while the benthic fungal diversity is shaped by water depth, salinity, and sediment C and N availability. (vi) Bacteriophages are the predominant group of viruses, while among viruses infecting eukaryotic hosts, Phycodnaviridae are the most abundant; the Baltic Sea virome is contaminated with viruses originating from urban and/or industrial habitats. These features make the Baltic Sea microbiome specific and unique among other marine environments.

波罗的海微生物的生物多样性:鉴定海洋微生物新方法的力量。
直到最近,有关波罗的海整个微生物群落多样性的数据还相对稀少。然而,现代分子方法为这一领域提供了新的见解,并取得了令人感兴趣的成果。这些结果可归纳如下(i) 与东北大西洋的种群相比,虽然低盐度导致多细胞物种的生物多样性减少,但 细菌多样性并没有减少。(ii) 在蓝藻中,从基因丰度角度看,微囊藻类占优势,而从生物量角度看,丝状蓝藻占优 势。(iii) 硅藻和甲藻的多样性比几十年前描述的大得多;然而,对这些类群的分子研究仍 然很少。(iv) 对其他原生动物群落的了解明显不足。(v) 盐度是浮游真菌群落组成的主要限制参数,而底栖真菌多样性则受水深、盐度、沉积物 C 和 N 可利用性的影响。(vi) 噬菌体是最主要的病毒群,而在感染真核宿主的病毒中,噬菌体病毒科(Phycodnaviridae)的数量最多;波罗的海病毒群受到来自城市和/或工业栖息地的病毒的污染。这些特点使得波罗的海微生物群具有特殊性,在其他海洋环境中独一无二。
