This review summarizes the present state of knowledge regarding the toxic, bloom-forming
cyanobacterium, Microcystis, with a specific focus on its geographic distribution, toxins …

Microcystis is a cyanobacterium that forms toxic blooms in freshwater ecosystems around
the world. Biological variation among taxa within the genus is apparent through genetic and …

Interactions between bacteria and phytoplankton in the phycosphere have impacts at the
scale of whole ecosystems, including the development of harmful algal blooms. The …

Bacterial community composition of different sized aggregates within the Microcystis
cyanobacterial phycosphere were determined during summer and fall in Lake Taihu, a …

Confocal and scanning electron microscopic observations have previously shown the strong
bacterial association of Microcystis aeruginosa cells on their surfaces. DNA-based analyses …

The factors and processes driving cyanobacterial blooms in eutrophic freshwater
ecosystems have been extensively studied in the past decade. A growing number of these …

Cyanobacterial blooms occur in lakes worldwide, producing toxins that pose a serious
public health threat. Eutrophication caused by human activities and warmer temperatures …

Bacteria play key roles in the function and diversity of aquatic systems, but aside from study
of specific bloom systems, little is known about the diversity or biogeography of bacteria …

In the oligotrophic oceans, key autotrophs depend on “helper” bacteria to reduce oxidative
stress from hydrogen peroxide (H2O2) in the extracellular environment. H2O2 is also a …

In eutrophic lakes, heterotrophic bacteria are closely associated with algal detritus and play
a crucial role in nutrient cycling. However, the seasonal and spatial dynamics of free‐living …
