The origin of multicellularity in cyanobacteria [PDF]

open access: yesBMC Evolutionary Biology, 2011
Cyanobacteria are one of the oldest and morphologically most diverse prokaryotic phyla on our planet. The early development of an oxygen-containing atmosphere approximately 2.45-2.22 billion years ago is attributed to the photosynthetic activity of cyanobacteria. Furthermore, they are one of the few prokaryotic phyla where multicellularity has evolved.

Cyanobacteria: Review of Current Potentials and Applications

open access: yesEnvironments, 2020
Continual increases in the human population and growing concerns related to the energy crisis, food security, disease outbreaks, global warming, and other environmental issues require a sustainable solution from nature.

Cyanobacteria of the Genus Prochlorothrix† [PDF]

open access: yesFrontiers in Microbiology, 2012
Green cyanobacteria differ from the blue-green cyanobacteria by the possession of a chlorophyll-containing light-harvesting antenna. Three genera of the green cyanobacteria namely Acaryochloris, Prochlorococcus, and Prochloron are unicellular and inhabit marine environments.

Effects of Solar Radiation on the Cyanobacteria: Diversity, Molecular Phylogeny, and Metabolic Activity

open access: yesFrontiers in Ecology and Evolution, 2022
Cyanobacteria bloom is a global aquatic ecological problem that seriously threatens human health and social development. The outbreak of cyanobacteria bloom is affected by various environmental factors, among which light dose is an essential factor.

The Toxins of Cyanobacteria [PDF]

open access: yesActa Medica (Hradec Kralove, Czech Republic), 2001
Cyanobacteria, formerly called ”blue-green algae“, are simple, primitive photosynthetic microorganism wide occurrence in fresh, brackish and salt waters. Forty different genera ofCyanobacteriaare known and many of them are producers of potent toxins responsible for a wide array of human illnesses, aquatic mammal and bird morbidity and mortality, and ...

Dynamics of the cyanobacterial water bloom with focus to Microcystis and its relationship with environmental factors in Brno reservoir

open access: yesActa Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2013
Our paper brings new information about long-term changes of the phytoplankton communities in the Brno reservoir with the focus on the Microcystis abundance using the semi-monthly monitoring data covering the period 2006–2012.

Generic assignments, strain histories, and properties of pure cultures of cyanobacteria

open access: yes, 1979
Summary: On the basis of a comparative study of 178 strains of cyanobacteria, representative of this group of prokaryotes, revised definitions of many genera are proposed.

Toxic Cyanobacteria: A Growing Threat to Water and Air Quality.

open access: yesEnvironmental Science and Technology, 2020
The global expansion of harmful cyanobacterial blooms (CyanoHABs) poses an increasing threat to public health. CyanoHABs are characterized by the production of toxic metabolites known as cyanotoxins.

Oxygenic photosynthetic responses of cyanobacteria exposed under an M-dwarf starlight simulator: Implications for exoplanet's habitability [PDF]

open access: yesFront. Plant Sci. 14:1070359 (2023), 2023
Introduction: The search for life on distant exoplanets is expected to rely on atmospheric biosignatures detection, such as oxygen of biological origin. However, it is not demonstrated how much oxygenic photosynthesis, which on Earth depends on visible light, could work under spectral conditions simulating exoplanets orbiting the Habitable Zone of M ...

Cyanobacteria bloom prevention and control and salvage disposal integrated management system [PDF]

open access: yesE3S Web of Conferences, 2019
Cyanobacteria are large single-cell prokaryotes that can undergo oxygen-producing photosynthesis. However, if the cyanobacteria are contaminated by nitrogen, phosphorus and other elements, cyanobacteria will cause the phenomenon of “water bloom” in the ...
