Bioluminescence is a spectacular feature of some prokaryotes. In the present work, we address the distribution of bioluminescence among bacteria isolated from the White Sea finfishes. Luminous bacteria are widely distributed throughout the World Ocean. Many strains have been isolated and described for tropical latitudes, while Nordic seas still remain quite a white spot in studying bioluminescence of bacteria. We describe the strains related to the two main genera of luminous bacteria, Photobacterium and Aliivibrio, as well as Shewanella and Vibrio. They are related to families Vibrionaceae and Shewanellaceae of the Gammaproteobacteria class. Here, we at the first time, report the bioluminescence of the Enterobacteriaceae Kosakonia cowanii. Moreover, we applied the polyphasic approach to identify and describe the isolated microorganisms. The data on sequencing, diversity of cell fine structure, and light emission spectra at room temperature on the solid medium are discussed. The bacteria are characterized by features in their light emission spectra. It may reflect possible molecular mechanisms of bioluminescence as well as features of bacterial composition. The obtained data expands the existing body of knowledge about the bioluminescence spread among the bacteria of Nordic latitudes and provides complex information that is crucial for their precise identification.

从白海有鳍鱼类中分离出的生物发光细菌菌株：光细菌属，Aliivibrio，弧菌，希瓦氏菌和第一发光科萨科尼亚属。

生物发光是某些原核生物的引人注目的特征。在当前的工作中，我们解决了从白海有鳍鱼类分离出的细菌中生物发光的分布。发光细菌在世界海洋中广泛分布。已经分离出许多菌株，并描述了热带纬度，而北欧海域在研究细菌的生物发光方面仍然是一个白点。我们描述了与发光细菌的两个主要属有关的菌株，即光细菌和Aliivibrio，以及希瓦氏菌和弧菌。它们与γ-变形杆菌属的弧菌科和Shewanellaceae科有关。在这里，我们是第一次报告肠杆菌科小叶锦鸡儿的生物发光。此外，我们应用了多相方法来识别和描述分离出的微生物。讨论了关于测序，细胞精细结构多样性以及室温下在固体培养基上的发光光谱的数据。细菌的特征在于其发光光谱。它可能反映了生物发光的可能分子机制以及细菌组成的特征。获得的数据扩展了有关北欧纬度细菌间生物发光分布的现有知识，并提供了对其精确识别至关重要的复杂信息。
