Management of Biesboch reservoirs for quality control with special reference to eutrophication [PDF]
, 1992 The three Biesbosch Reservoirs are pumped storage reservoirs, fed with rather polluted and highly eutrophic water from the River Meuse. Air injection at the bottom of the reservoirs prevents thermal stratification, which would otherwise result in serious

Angewandte Chemie, EarlyView.Marine polyhydroxylated macrolides’ drug discovery potential is limited by structural complexity and scarce material supply, hindering structure assignment, synthesis, and biological studies. Here, we present an integrated workflow that combines chemogenomic profiling, ultra‐high‐resolution NMR‐guided structural revision and stereochemical assignment ...

Symbiotic unicellular cyanobacteria fix nitrogen in the Arctic Ocean
Proceedings of the National Academy of Sciences of the United States of America, 2018 Significance Biological dinitrogen (N2) fixation (BNF) is an important source of nitrogen in marine systems. Until recently, it was believed to be primarily limited to subtropical open oceans. Marine BNF is mainly attributed to cyanobacteria.

Developmental Biology in Cyanobacteria [PDF]
Life, 2019 Filamentous, heterocyst-forming cyanobacteria are phototrophic multicellular organisms in which N2-fixing heterocysts and CO2-fixing vegetative cells exchange regulators and nutrients [...]

Two Novel S‐methyltransferases Confer Dimethylsulfide Production in Actinomycetota
Advanced Science, EarlyView.This study identifies two novel S‐adenosine‐methionine‐dependent methyltransferases, MddM1 and MddM2, in actinomycetes from the Mariana Trench. These enzymes can convert toxic hydrogen sulfide (H2S) and methanethiol (MeSH) into dimethylsulfide (DMS), serving as a cellular detoxification and oxidative stress response.

Do Cyanobacteria Blooms Enhance Parasite Loads in Lake Erie Yellow Perch? [PDF]
, 2020 Harmful Algal Blooms composed of cyanobacteria (HABs) are a major concern globally, especially in ecosystems that support commercial and recreational fisheries. Although HABs have been shown to negatively affect the services provided by ecosystems (e.g.,
