The molecular ecology of Microcystis sp. blooms in the San Francisco Estuary

open access: bronzeEnvironmental Microbiology, 2017
SummaryHarmful blooms of the cyanobacterium Microcystis sp. have become increasingly pervasive in the San Francisco Estuary Delta (USA) since the early 2000s and their rise has coincided with substantial decreases in several important fish species. Direct and indirect effects Microcystis blooms may have on the Delta food web were investigated.

Influence of Microcystis sp. and freshwater algae on pH: Changes in their growth associated with sediment [PDF]

open access: greenEnvironmental Pollution, 2020
Samples from two reservoirs with eutrophication problems, located in Pontevedra and Ourense (Northwestern Spain), were cultured, along with a third crop from a reservoir with no problems detected in Ourense (Northwestern Spain). The samples were grown under the same conditions (with an average temperature of 21 ± 2 °C, and a 3000 lux light intensity ...

Nitrogen Substrate Impacts Microcystis aeruginosa Exometabolome Composition. [PDF]

open access: yesEnviron Microbiol Rep
We used untargeted metabolomics to identify differences in the compounds exuded into culture media by three strains of M. aeruginosa grown on three N substrate treatments (NO3−, NH4+, and urea). Results showed that the usage of different N substrates changes the exometabolome of toxic and non‐toxic strains of M. aeruginosa.

Effective dilution rate to suppress the risk of Microcystis blooms in Lake Tega, Japan, based on a competitive growth simulation model

open access: yesWater Supply, 2022
Although water transfer as an efficient method to improve water quality and control Microcystis blooms in lakes has been executed for several decades, few studies have examined effective dilution rates depending on various water qualities.

Genomic signatures of Lake Erie bacteria suggest interaction in the Microcystis phycosphere.

open access: yesPLoS ONE, 2021
Microbial interactions in harmful algal bloom (HAB) communities have been examined in marine systems, but are poorly studied in fresh waters. To investigate HAB-microbe interactions, we isolated bacteria with close associations to bloom-forming ...

Simultaneous Removal of the Freshwater Bloom-Forming Cyanobacterium Microcystis and Cyanotoxin Microcystins via Combined Use of Algicidal Bacterial Filtrate and the Microcystin-Degrading Enzymatic Agent, MlrA

open access: yesMicroorganisms, 2021
Freshwater cyanobacterial blooms (e.g., Microcystis blooms) constitute a major global environmental problem because of their risks to public health and aquatic ecological systems.

Co-occurrence of microcystin and microginin congeners in Brazilian strains ofMicrocystissp. [PDF]

open access: bronzeFEMS Microbiology Ecology, 2012
Species of Microcystis are the most common bloom-forming cyanobacteria in several countries. Despite extensive studies regarding the production of bioactive cyanopeptides in this genus, there are limited data on isolated strains from Brazil. Three Microcystis sp.

Microcystis sp. AE03 strain in Dal Lake harbors cylindrospermopsin and microcystin synthetase gene cluster

open access: yesFrontiers in Sustainable Food Systems, 2022
Cyanobacterial harmful algal blooms (CHABs) are increasing at an alarming rate in different water bodies worldwide. In India, CHAB events in water bodies such as Dal Lake have been sporadically reported with no study done to characterize the ...
