Covariance of Phytoplankton, Bacteria, and Zooplankton Communities Within Microcystis Blooms in San Francisco Estuary

open access: yesFrontiers in Microbiology, 2021
Microcystis blooms have occurred in upper San Francisco Estuary (USFE) since 1999, but their potential impacts on plankton communities have not been fully quantified.

Coordinated Diel Gene Expression of Cyanobacteria and Their Microbiome

open access: yesMicroorganisms, 2021
Diel rhythms have been well recognized in cyanobacterial metabolisms. However, whether this programmed activity of cyanobacteria could elicit coordinated diel gene expressions in microorganisms (microbiome) that co-occur with cyanobacteria and how such ...

The Dynamics of Microcystis Genotypes and Microcystin Production and Associations with Environmental Factors during Blooms in Lake Chaohu, China

open access: yesToxins, 2014
Lake Chaohu, which is a large, shallow, hypertrophic freshwater lake in southeastern China, has been experiencing lake-wide toxic Microcystis blooms in recent decades.

Further characterization of glycine-containing microcystins from the McMurdo Dry Valleys of Antarctica [PDF]

open access: yes, 2015
Microcystins are hepatotoxic cyclic peptides produced by several cyanobacterial genera worldwide. In 2008, our research group identified eight new glycine-containing microcystin congeners in two hydro-terrestrial mat samples from the McMurdo Dry Valleys ...

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

open access: yesFrontiers 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 ...

Use of a generalized additive model to investigate key abiotic factors affecting microcystin cellular quotas in heavy bloom areas of Lake Taihu. [PDF]

open access: yesPLoS ONE, 2012
Lake Taihu is the third largest freshwater lake in China and is suffering from serious cyanobacterial blooms with the associated drinking water contamination by microcystin (MC) for millions of citizens.

Investigation of cellular structure and metabolic activity of Microcystis cells treated by chlorination

open access: yesWater Supply, 2023
Frequent outbreaks of cyanobacterial blooms in lakes and reservoirs can result in the deterioration of drinking water quality. Chlorine has been used as an oxidant or algicide to treat cyanobacteria-laden source waters, but influences of chlorination on ...

The mosaic structure of the mcyABC operon in Microcystis [PDF]

open access: yesMicrobiology, 2008
An extensive study of the mcyABC genes and regions flanking the mcy gene cluster was performed in naturally occurring Microcystis strains. Lack of methylation in strains producing only desmethyl(7)-microcystin was found to be associated with point mutations in substrate-binding sequence motifs of the N-methyltransferase (NMT) domain in McyA.
