The abundance of bacterioneuston and bacterioplankton and their taxonomic composition were determined with the fluorescence in situ hybridization (FISH) method in the harbor channel in Ustka. Among bacteria inhabiting the surface microlayer and subsurface water two phylogenetic groups dominated: Gammaproteobacteria and Cytophaga-Flavobacterium. The abundance of bacterial taxonomic groups in the water of the studied channel showed typical ranking, i.e., Gammaproteobacteria > Cytophaga-Flavobacterium > Marine alpha cluster > Pseudomonas > Vibrio. Total prokaryotic cell differed along the vertical and horizontal profiles. Similar taxonomic composition of bacterioneuston and bacterioplankton in both studied profiles were noted. All studied taxonomic groups occurred more often in the surface microlayer than subsurface water.

波罗的海南部沿海海港河道内细菌游动藻和浮游植物的数量和系统发育多样性

用荧光原位杂交(FISH)方法在乌斯特卡港口通道中确定了eueustoneuston和细菌的浮游生物的丰度及其分类学组成。在居住于表层微层和地下水的细菌中,两个系统发生族群占主导地位:γ变形杆菌细胞吞噬黄杆菌。细菌分类群在所研究的通道的水的丰度表明典型的排名,即,γ-变形菌>噬纤维菌-黄杆菌>海洋阿尔法簇>假单胞菌>弧菌。总的原核细胞沿垂直和水平方向不同。在两个研究曲线中都发现了类似的细菌游动素和浮游细菌的生物分类组成。所有研究的生物分类群比地表水更常出现在地表微层。
