Climate change amplifies the risk of potentially toxigenic cyanobacteria

Global Change Biology, Journal Year: 2023, Volume and Issue: 29(18), P. 5240 - 5249

Published: July 6, 2023

Abstract Cyanobacterial blooms pose a significant threat to water security, with anthropogenic forcing being implicated as key driver behind the recent upsurge and global expansion of cyanobacteria in modern times. The potential effects land‐use alterations climate change can lead complicated, less‐predictable scenarios cyanobacterial management, especially when forecasting toxin risks. There is growing need for further investigations into specific stressors that stimulate toxins, well resolving uncertainty surrounding historical or contemporary nature cyanobacterial‐associated To address this gap, we employed paleolimnological approach reconstruct abundance microcystin‐producing temperate lakes situated along human impact gradient. We identified breakpoints (i.e., points abrupt change) these time series examined landscape climatic properties on their occurrence. Our findings indicate subject greater influence exhibited an earlier onset biomass by 40 years compared less‐impacted lakes, emerging dominant predictor. Moreover, increased both high‐ low‐impact around 1980s, warming primary driver. chronicle importance increasing risk toxigenic freshwater resources.

Water Quality and Land Use Shape Bacterial Communities Across 621 Canadian Lakes

Environmental Microbiology, Journal Year: 2025, Volume and Issue: 27(1)

Published: Jan. 1, 2025

Human activities such as agriculture and urban development are linked to water quality degradation. Canada represents a large heterogeneous landscape of freshwater lakes, where variations in climate, geography geology interact with land cover alteration influence differently across regions. In this study, we investigated the use on bacterial communities 12 ecozones. At pan-Canadian scale, total phosphorus (TP) was most significant variable influencing community structure, pronounced shift observed at 110 μg/L TP, corresponding transition from eutrophic hypereutrophic conditions. regional significantly explained structure all terms effect, and, lesser extent, urbanisation were variables structure. Regionally, ecozones characterised by extensive agriculture, consistently explaining Likewise, extensively urbanised ecozones, Overall, these results demonstrate that richness influenced shaped different ways.

Investigation on Lanthanum Modified Kaolinite for Control of Cyanobacterial Growth and Microcystin Production

Water, Journal Year: 2025, Volume and Issue: 17(3), P. 428 - 428

Published: Feb. 4, 2025

Eutrophication and its resultant cyanobacterial blooms are a severe environmental issue in global water bodies, phosphate is regarded as one of the primary triggers. In this study, situ-synthesized heated kaolinite lanthanum hydroxide composite (HKL-LH) was used to treat through removal. A typical cyanobacteria species—Microcystis aeruginosa—was selected target organism. HKL-LH efficiently removed solution with inoculation M. aeruginosa over course day. good performance on control initial cell densities ranging from 104 cells mL−1 105 observed. Although genetic expression relating photosynthesis division upregulated under stress phosphorus deficiency, growth significantly inhibited, i.e., inhibition rate up 98% achieved by 0.1g L−1 HKL-LH. addition growth, photosynthetic activity viability were decreased Furthermore, production associated toxins (microcystins) algal organic matters effectively which can reduce ecological risk challenges that follow treatment. it shown has excellent application potential mitigation eutrophic water.

Metagenomic insights into cyanotoxin dynamics in a Mexican subtropical lake

Chemosphere, Journal Year: 2025, Volume and Issue: 376, P. 144285 - 144285

Valle de Bravo is a vital water supply for part of the metropolitan area Mexico megacity, providing 30% City's demand. This body has experienced an acceleration in its trophic status, going from oligotrophic to eutrophic just few years. temperate lake (at tropical latitude) persistent bloom dominated by variety co-occurring cyanobacteria, many which have toxigenic potential based on microscopic identification, that makes it difficult or even impractical identify cyanotoxin producers. To unravel this complexity and directly genera, we showed integrating classical approaches with metagenomic required. We first characterized, genes metagenomes assembled genomes, Cyanobacteria. found Microcystis was most dominant cyanobacterial genus sole carrier mcy operon, making only microcystin producer. then quantified twenty-one different cyanopeptides, including twelve congeners using high-performance liquid chromatography-high-resolution. Nine microcystins (MCs) emerging anabaenopeptin-A -B were at varying concentrations throughout year, MC-LA being common abundant. Our findings, constrained our sampling strategy, indicate conventional biomarkers (e.g., toxin genes) not consistently reliable indicators freshwater system.

Harmful blooms across a longitudinal gradient in central Europe during heatwave: Cyanobacteria biomass, cyanotoxins, and nutrients

Ecological Indicators, Journal Year: 2024, Volume and Issue: 160, P. 111929 - 111929

Published: March 1, 2024

Climate change has increased the frequency, duration and intensity of heatwaves in Europe. These extreme events result alterations physical, chemical, biological properties lakes that may synergistically promote cyanobacterial dominance. In our study we focused on blooms distributed over a longitudinal gradient Central Europe during one "top ten European heat waves" summer 2015. 92 were included study, located across three climatic subregions: cool northern lakes, situated Lithuania, temperate Poland, warm Croatia. The objective was to determine if biomass, predominant species, cyanotoxin concentration differed, south-north gradient, as function water temperature, total phosphorus, nitrogen. Statistical significance observed patterns tested using Kruskal-Wallis rank sum test generalized linear model. We found lowest average epilimnion but highest biomass northern, 'cool' while temperature with southern, 'warm' lakes. cyanotoxins also Total phosphorus nitrogen correlated significantly some species (mainly Planktothrix agardhii), regardless latitude. Only (microcystins anatoxin-a) dominant (P. agardhii). Our results emphasized differences weaves impact various latitudes, strongest increase toxic high latitudes. On other hand, nutrients directly enhanced all studied latitudes cyanobacteria dominating might be recognized ecological indicators climate change, especially north-eastern part
