Dynamic response of bacterial communities to Microcystis blooms: A three-year study

The Science of The Total Environment, Год журнала: 2023, Номер 902, С. 165888 - 165888

Although nutrient availability is widely recognized as the driving force behind Microcystis blooms, identifying microorganisms that play a pivotal role in their formation challenging task. Our understanding of contribution bacterial communities to development blooms remains incomplete, despite fact relationship between and has been extensively investigated. Most studies have focused on interaction for single year rather than multiple years. To determine key bacteria crucial we collected samples from three sites Daechung Reservoir (Chuso, Hoenam, Janggye) over years (2017, 2019, 2020). results indicated bloom-associated were more conserved across stations Bacterial could be separated into modules corresponding different phases blooms. Dolichospermum Aphanizomenon belonged same module, whereas module was distinct. The microbial recurrent association network (MRAN) showed amplicon sequence variants (ASVs) directly linked Pseudanabaena, Microscillaceae, Sutterellaceae, Flavobacterium, Candidatus Aquiluna, Bryobacter, DSSD61. These ASVs also identified indicators bloom stage, indicating they fundamental biological elements Overall, our study highlights that, although change annually, continue share core may maintenance

Interplays between cyanobacterial blooms and antibiotic resistance genes

Environment International, Год журнала: 2023, Номер 181, С. 108268 - 108268

Cyanobacterial harmful algal blooms (cyanoHABs), which are a form of microbial dysbiosis in freshwater environments, an emerging environmental and public health concern. Additionally, the environment serves as reservoir antibiotic resistance genes (ARGs), pose risk transmission during dysbiosis, such cyanoHABs. However, interactions between potential synergistic pollutants, cyanoHABs, ARGs remain poorly understood. During Microcystis high microcystin levels were dominant all nine regions river sampled. The resistome, mobilome, microbiome interrelated linked to physicochemical properties freshwater. Planktothrix Pseudanabaena competed with Actinobacteriota Proteobacteria Forty two ARG carriers identified, most belonged Proteobacteria. showed strong correlation density, decreased severity cyanoHAB. Although due reduction mobile gene elements (MGEs) virulence factors (VFs) increased. We explored relationship cyanoHABs for interaction. Our findings demonstrated that cyanobacteria compete commensal bacteria Proteobacteria, carry freshwater, resulting levels. Moreover, generate biotic abiotic stress microbiome, may lead increase MGEs VFs. Exploration intricate interplays pathobiome not only revealed mechanisms underlying dynamics but also emphasizes need prioritize prevention management ARGs.

Relic DNA obscures DNA‐based profiling of multiple microbial taxonomic groups in a river‐reservoir ecosystem

Molecular Ecology, Год журнала: 2023, Номер 32(17), С. 4940 - 4952

Опубликована: Июль 15, 2023

Numerous studies have investigated the spatiotemporal variability in water microbial communities, yet effects of relic DNA on community profiles, especially microeukaryotes, remain far from fully understood. Here, total and active bacterial microeukaryotic compositions were characterized using propidium monoazide (PMA) treatment coupled with high-throughput sequencing a river-reservoir ecosystem. Beta diversity analysis showed significant difference composition between both PMA untreated treated bacteria microeukaryotes; however, differentiating effect was much stronger for microeukaryotes. Relic only resulted underestimation relative abundances Bacteroidota Nitrospirota, while other taxa exhibited no changes. As some phytoplankton (e.g. Chlorophyta, Dinoflagellata Ochrophyta) fungi greater after removal, whereas Cercozoa Ciliophora opposite trend. Moreover, removal weakened size complexity cross-trophic networks significantly changed relationships environmental factors composition. However, there rates temporal turnover samples either or Overall, our results imply that presence waters can give misleading information composition, co-occurrence their conditions. More abundance, decay rate functioning nonviable freshwater ecosystems are highly recommended future.

Abstract The accelerated decline in Arctic sea-ice cover and duration is enabling the opening of marine passages improving access to natural resources. increasing accessibility navigation resource exploration production brings risks accidental hydrocarbon releases into waters, posing a major threat ecosystems where oil may persist for many years, especially beach sediment. composition response microbial community contamination on beaches remain poorly understood. To address this, we analyzed structure identified degradation genes among Northwest Passage intertidal sediments shoreline seawater from five high beaches. Our results 16S/18S rRNA genes, long-read metagenomes, metagenome-assembled genomes reveal metabolic capabilities degrader community, as well tight cross-habitat cross-kingdom interactions dominated by lineages that are common often dominant polar coastal habitat, but distinct petroleum hydrocarbon-contaminated sites. In sediment habitats, Granulosicoccus sp. Cyclocasticus were potential hydrocarbon-degraders, our metagenomes revealed small proportion microalgae algal viruses possessing key biodegradative genes. This research demonstrates communities possess ability attenuation. findings provide new insights viral microalgal might represent an important contribution removal hydrocarbons under harsh environmental conditions pristine, cold, oil-free environment threatened spills.
