“…Temperature has often been identified as one of the major abiotic environmental variables contributing, significantly, to shaping aquatic microbial communities. For instance, Mai et al 12 identified that temperature is responsible for the shifts of bacterial community in the Pearl River estuary. Similarly, temperature drove spatiotemporal variation of the bacterial composition in freshwater Lake Taihu 27 .…”

“…A number of published data have illustrated spatial heterogeneity of bacterial communities in freshwater ecosystems 8 – 10 . Bacterial population’s seasonality in different water types and variant ecosystems, such as bacterioplankton communities 11 , 12 , bacterial communities in sediments 13 , wastewater treatment plants 14 , 15 , and drinking water works 16 , 17 , as well as in the estuarine ecosystems 18 , 19 , has repeatedly been observed. However, seasonal impacts on the lotic bacterial community structure remain sparsely addressed.…”

Aquatic microbial diversity, composition, and dynamics play vital roles in sustaining water ecosystem functionality. Yet, there is still limited knowledge on bacterial seasonal dynamics in lotic environments. This study explores a temporal pattern of bacterial community structures in lotic freshwater over a 2-year period. The aquatic bacterial communities were assessed using Illumina MiSeq sequencing of 16S rRNA genes. Overall, the communities were dominated by α-, β-, and γ-Proteobacteria, Bacteroidetes, Flavobacteriia, and Sphingobacteriia. The bacterial compositions varied substantially in response to seasonal changes (cold vs. warm), but they were rather stable within the same season. Furthermore, higher diversity was observed in cold seasons compared to warm periods. The combined seasonal-environmental impact of different physico-chemical parameters was assessed statistically, and temperature, suspended solids, and nitrogen were determined to be the primary abiotic factors shaping the temporal bacterial assemblages. This study enriches particular knowledge on the seasonal succession of the lotic freshwater bacteria.

“…Numerous previous studies have shown the spatiotemporal variation of bacterial community richness and diversity in aquatic ecosystems (Adhikari et al, 2019;Dai et al, 2016;Mai et al, 2018;Mao et al, 2019;Yang et al, 2019;Sheng et al, 2016;Zhang et al, 2014Zhang et al, , 2019aZhu et al, 2019). However, little is known about the shift of bacterial richness and diversity in given urban rivers.…”

“…There is a large degree of variation in bacterial communities in terms of taxonomic composition in aquatic ecosystems (Adhikari et al, 2019;Chen et al, 2018;Dai et al, 2016;Mai et al, 2018;Sun et al, 2011;Xia et al, 2014;Yang et al, 2019;Zhang et al, 2014;Zhu et al, 2019), whereas the characteristics of bacterial communities in given urban rivers remains poorly understood. In this study, the results of PCoA and PerMANOVA revealed strong heterogeneity in the structure of planktonic and sediment bacterial communities, which was supported by previous studies in river systems Liu et al, 2018;Staley et al, 2015;Wang et al, 2018).…”

Urban rivers represent a unique ecosystem in which pollution occurs regularly, altering the biogeochemical characteristics of waterbodies and sediments. However, little is presently known about the spatiotemporal patterns of planktonic and sediment bacterial community diversities and compositions in urban rivers. Herein, Illumina MiSeq high-throughput sequencing was performed to reveal the spatiotemporal dynamics of bacterial populations in Liangtan River, a heavily polluted urban river in Chongqing City (China). The results showed the richness and diversity of sediment bacteria were significantly higher than those of planktonic bacteria, whereas a strong overlap (46.7%) in OTUs was identified between water and sediment samples. Bacterial community composition remarkably differed in waters and sediments. Planktonic bacterial communities were dominated by Proteobacteria, Bacteroidetes, Cyanobacteria and Actinobacteria, while sediment bacterial communities mainly included Proteobacteria, Actinobacteria, Chloroflexi and Bacteroidetes. Additionally, several taxonomic groups of potential bacterial pathogens showed an increasing trend in water and sediment samples from residential and industrial areas (RI). Variation partition analysis (VPA) indicated that temperature and nutrient were identified as the main drivers determining the planktonic and sediment bacterial assemblages. These results highlight that bacterial communities in the polluted urban river exhibit spatiotemporal variation due to the combined influence of environmental factors associated with sewage discharge and hydropower dams.

A novel marine actinobacterium, strain SCSIO 58843T, was isolated from the sediment sample collected from the South China Sea. Strain SCSIO 58843T was Gram-stain-positive, aerobic and rod shaped. The whole-cell hydrolysis of amino acids contained dd-DAP, alanine, glutamic acid, glycine and aspartic acid. The main menaquinone was MK-9(H8). The major fatty acids were C17 : 1 ω8c and C17 : 0. The major phospholipids were diphosphatidylglycerol (DPG), phosphatidylinositol (PI), phospatidylcholine (PC) and phosphatidylinositolmannoside (PIM). The G+C content of the genomic DNA was 72.5 %. Phylogenetic analysis of the 16S rRNA gene sequences showed that strain SCSIO 58843T formed a new lineage in the family Iamiaceae and had the highest similarity of 93.8 % with Iamia majanohamensis DSM 19957T. Strain SCSIO 58843T can be distinguished from these known genera in the family Iamiaceae by polyphasic data analyses, and represents a novel genus and novel species, for which Actinomarinicola tropica gen. nov., sp. nov is proposed with the type strain SCSIO 58843T(=KCTC 49408T=CGMCC 1.17503T).
