“…Microbial structures or communities, basically bacteria, of the water system contribute significantly to the aquatic ecosystem due to their role in biogeochemical processes ( Han et al, 2019 ). Such communities have a high diversity level that enhances their function and stability ( Lu et al, 2020 ).…”

“…In addition, microbial communities in lake networks could be appropriate bioresources for industry, agriculture, and relevant divisions ( Yadav et al, 2018 ). Bacteria is considered the most important component of the microbial community in aquatic ecosystems that is responsible for vital global ecological processes ( Han et al, 2019 ). Bacterial type and concentration can provide information about the water quality and contamination source.…”

“…In this study, T and DO were the major factors that drove variations in the epiphytic bacterial community in June and August. Nutrient dynamics were the major factors for the epiphytic bacterial community and functional potential of the physicochemical properties that have been studied (Han et al, 2019). In this study, the determinations of water quality showed that the TP differed significantly among the three sampling times.…”

“…The results indicated that the Cytophaga-Flavobacter-Bacteroidetes group, Alphaproteobacteria, and Betaproteobacteria were abundant (Hempel et al, 2009). Currently, 16S rRNA gene high-throughput sequencing is the routine method used to study the epiphytic bacterial communities of submerged macrophytes, such as Myriophyllum verticillatum, H. verticillata, V. natans, M. spicatum, P. malaianus, P. lucens, among others (Han et al, 2019;Liu et al, 2019Liu et al, , 2020Yan et al, 2019;He et al, 2020). Previous studies suggested that several factors, such as the plant species, water environment, sampling sites and growing season, affected the composition of the epiphytic bacterial community on submerged macrophytes (Hempel et al, 2009;Cai et al, 2013;He et al, 2020).…”

Epiphytic bacteria on the surfaces of submerged macrophytes play important roles in the growth of the host plant, nutrient cycling, and the conversion of pollutants in aquatic systems. A knowledge of the epiphytic bacterial community structure could help us to understand these roles. In this study, the abundance, diversity, and functions of the epiphytic bacterial community of Myriophyllum spicatum collected from Baiyangdian Lake in June, August, and October 2019 were studied using quantitative PCR (qPCR), high-throughput sequencing, and the prediction of functions. An analysis using qPCR showed that the epiphytic bacteria were the most abundant in October and the least abundant in August. High-throughput sequencing revealed that Proteobacteria, Gammaproteobacteria, and Aeromonas were the dominant phylum, class, and genus in all the samples. The common analyses of operational taxonomic units (OTUs), NMDS, and LDA showed that the epiphytic bacterial communities were clustered together based on the seasons. The results of a canonical correlation analysis (CCA) showed that the key water quality index that affected the changes of epiphytic bacterial community of M. spicatum was the total phosphorus (TP). The changes in abundance of Gammaproteobacteria negatively correlated with the TP. Predictive results from FAPROTAX showed that the predominant biogeochemical cycle functions of the epiphytic bacterial community were chemoheterotrophy, nitrate reduction, and fermentation. These results suggest that the epiphytic bacterial community of M. spicatum from Baiyangdian Lake varies substantially with the seasons and environmental conditions.

“…caroliniana ) of plants evaluated in our study, which agreed with the results from Xia et al (2020) . The structure of the epiphytic bacterial communities also depends on the environmental conditions ( Bao et al, 2020 ; Comba González et al, 2021 ) and the growth states and even decompositions of the hosts ( Han et al, 2019 ); thus, it is not a simple reflection of the host species.…”

The combination of submerged plants and snails can combat eutrophication of freshwater systems by suppressing algal growth and assimilating nutrients. By consuming epiphytes, snails can benefit the growth of submerged plants. However, the efficiency of this phytoremediation strategy may depend on the microbes associated with the plants and snails. In this study, we compared the epiphytic bacterial communities on submerged plants (Vallisneria natans and Cabomba caroliniana) and intestinal bacterial communities of a snail, Bellamya aeruginosa, found on these plants using 16S rRNA gene sequencing. Epiphytic bacterial communities were similar between the two plant species and snails shared a high proportion of snail intestinal bacterial OTUs (75%) and genera (85%) with plants they grazed on. However, significant variations of Bray-Curtis distances differentiated epiphytic and intestinal bacterial communities. In addition, between the top 50 genera shared by intestinal and epiphytic bacterial communities, more Spearman correlations were detected within bacterial communities associated with snails than between communities associated with plants (190 vs. 143), and the correlations in epiphytic bacterial networks were more concentrated on certain genera, indicating they possessed distinct bacterial networks. This suggests the bacterial communities associated with snails do not depend strongly on the plant they graze on, which may be important for better understanding the role of snails in aquatic eco-restoration.
