Bacterioplankton community composition has become the center of research attention in recent years. Bacteria associated with toxic cyanobacteria blooms have attracted considerable interest. However, little is known about the environmental factors driving the bacteria community, including the impact of invasive cyanobacteria. Therefore, our aim has been to determine the relationships between heterotrophic bacteria and phytoplankton community composition across 24 Polish lakes with different contributions of cyanobacteria including the invasive species This analysis revealed that cyanobacteria were present in 16 lakes, while occurred in 14 lakes. Our results show that bacteria communities differed between lakes dominated by cyanobacteria and lakes with minor contributions of cyanobacteria but did not differ between lakes with and other lakes. Physical factors, including water and Secchi depth, were the major drivers of bacteria and phytoplankton community composition. However, in lakes dominated by cyanobacteria, bacterial community composition was also influenced by biotic factors such as the amount of , chlorophyll-a and total phytoplankton biomass. Thus, our study provides novel evidence on the influence of environmental factors and on lake bacteria communities.
近年来，细菌浮游生物群落组成已成为研究的焦点。与有毒蓝藻水华相关的细菌引起了相当大的关注。然而，关于驱动细菌群落的环境因素，包括入侵蓝藻的影响，人们知之甚少。因此，我们的目的是确定 24 个具有不同蓝藻（包括入侵物种 ）贡献的波兰湖泊中异养细菌和浮游植物群落组成之间的关系。
这一分析表明，16 个湖泊中存在蓝藻，而 存在于 14 个湖泊中。我们的研究结果表明，蓝藻占主导地位的湖泊和蓝藻贡献较小的湖泊中的细菌群落存在差异，但 和其他湖泊之间的细菌群落没有差异。物理因素，包括水温和透明度，是细菌和浮游植物群落组成的主要驱动因素。然而，在蓝藻占主导地位的湖泊中，细菌群落组成也受到生物因素的影响，如 的数量、叶绿素-a 和总浮游植物生物量。
因此，我们的研究提供了关于环境因素和 对湖泊细菌群落影响的新证据。
