摘要

本文研究了奥佩琴下湖水工改造前后(2016-2018年)和周边地区水工改造前后(2019-2021年)浮游细菌和底栖细菌的结构和功能指标。分析了水体和底泥中浮游细菌、底栖细菌、富营养化细菌和寡营养化细菌、细胞质膜受损细菌(死细胞)和电子传递链活跃细菌(活细胞)的数量、破坏强度和细菌分解水中有机物的季节动态。揭示了湖泊水体中卫生指示微生物的显著发展。对两个调查时期湖泊细菌种群的数量发育和功能进行了比较分析。所得结果可用于揭示在人为污染和重建水体中抗污染微生物群落的形成和功能机制,以及它们在自净化过程中的作用。

Structural and Functional Changes in Bacterial Population of the Lake as a Response to Hydrotechnical Construction (by Example of Opechen Nyzhne Lake, Kyiv, Ukraine)
The paper deals with structural and functional indicators of bacterioplankton and bacteriobenthos of Opechen Nizhny Lake before (2016-2018) and after (2019-2021) its hydrotechnical reconstruction and improvement of the surrounding areas are presented. The analysis of seasonal dynamics of bacterioplankton, bacteriobenthos, eutrophic and oligotrophic bacteria, bacteria with a damaged cytoplasmic membrane (dead cells) and bacteria with active electron transport chain (alive cells) number in water and bottom sediments, intensity of destruction and bacterial decomposition of organic matter in water was analyzed. Significant development of sanitary-indicative microorganisms in the lake water was revealed. The comparative analysis of the quantitative development and functioning of the bacterial population of the lake over two investigated periods was carried out. The results obtained can be used to reveal the mechanisms of formation and functioning of pollution-resistant microbial communities in anthropogenically polluted and reconstructed water bodies, as well as their role in the self-purification processes.

期刊介绍: This journal contains translations from the premier Russian and Eastern European periodicals in aquatic biology and aquatic ecosystems, supplemented by original articles from elsewhere. The journal publishes in the area of physiology, biochemistry, systematics, ecology and conservation of freshwater fish, invertebrates, vascular plants, zoo- and phytoplankton, as well as freshwater quality and toxicology. While most of the papers deal with inland waters, the journal also publishes articles reporting on expeditionary work, especially the Antarctic and tropical seas. Hydrobiological Journal is valuable to freshwater and marine biologists and chemists, limnologists, environmental scientists, oceanographers, and toxicologists.
