Enhanced Microbial Interactions and Deterministic Successions During Anoxic Decomposition of Microcystis Biomass in Lake Sediment

Frontiers in Microbiology, 2019
Microcystis biomass remineralization after blooming represents a hotspot of nutrient recycling in eutrophic lakes. Because Microcystis blooms are massively deposited on lake sediments, resulting in anoxic conditions, it is important to understand the ...

Growth and photosynthesis responses of microcystin (MC)- and non-MC-producing Microcystis strains during co-culture with the submerged macrophyte Myriophyllum spicatum

Water Science and Technology, 2022
The growth and photosynthetic responses of microcystin (MC)- and non-MC-producing Microcystis to the submerged macrophyte Myriophyllum spicatum were investigated under plant-Microcystis co-culture conditions (PMC + , PMC−), in comparison with their ...

Continental scale metagenomics reveals Microcystis‐induced synchrony among aquatic taxa is exacerbated by trophic cascades

Ecography, EarlyView.
Harmful Microcystis proliferation severely threatens aquatic ecosystems globally, but its impacts on food‐web stability remain poorly understood. Here, we analyzed 1309 metagenomic samples from freshwater ecosystems across China to investigate how Microcystis abundance affects synchrony among taxa in multi‐trophic food webs (from bacteriophages to ...

Polyphasic Characterization and Taxonomic Evaluation of a Bloom-Forming Strain Morphologically Resembling Radiocystis fernandoi (Chroococcales, Cyanobacteria) from Lake Erhai, China

Diversity, 2022
Microcystis-dominated blooms cause environmental and ecological impacts worldwide. However, it is sometimes challenging to correctly identify Microcystis and its related genera.

Statistical filtering to aid in the sorting of phytoplankton: The effects of image library size and phytoplankton shape

Limnology and Oceanography: Methods, EarlyView.
Abstract The demand for efficient image sorting methods has increased due to technological advancements that enable more intensive phytoplankton monitoring. Both statistical and machine learning algorithms can misidentify algal taxa in taxonomically diverse samples, in which phytoplankton morphology and image traits can vary.

Cyanopeptide Mixtures Induce Variable Synergistic and Antagonistic Effects Across Diverse Human Cell Lines

Environmental Toxicology, EarlyView.
ABSTRACT Cyanobacterial harmful algal blooms (cyanoHABs) threaten human, animal, and ecosystem health and safety through production of toxic secondary metabolites. Microcystis, a cosmopolitan bloom‐forming cyanobacterial genus, is well‐known for producing hepatotoxic microcystins (MCs), but it can produce many other bioactive cyanopeptides, such as ...

Synergistic and Antagonistic Effects of Chemical Pollutants and Parasitic Fungi on Cyanobacterial Metabolism

Environmental Toxicology, EarlyView.
ABSTRACT Freshwater ecosystems are increasingly impacted by anthropogenic pollutants, including the widely used herbicide metolachlor (MET) and cigarette butt (CB) litter. Parasites represent an additional biotic stressor that can modulate pollutant effects on their hosts.

Cyanobacterial Bloom Formation by Enhanced Ecological Adaptability and Competitive Advantage of Microcystis—Non-Negligible Role of Quorum Sensing

Microorganisms
Microcystis-dominated cyanobacterial blooms (MCBs) frequently occur in freshwaters worldwide due to massive Microcystis colony formation and severely threaten human and ecosystem health.
