Identification and Enumeration of Marine Chroococcoid Cyanobacteria by Immunofluorescence [PDF]

open access: yesApplied and Environmental Microbiology, 1983
We used an indirect immunofluorescence technique to permit the identification and enumeration of individual or closely related strains of chroococcoid cyanobacteria of the general Synechococcus and Synechocystis in natural seawater samples.

Integrating Oceanographic Data and Benthic Community Structure Temporal Series to Assess the Dynamics of a Marginal Reef

open access: yesFrontiers in Marine Science, 2021
Reefs are the richest marine ecosystems. Their benthic communities generate structural complexity and participate in nutrient cycles, providing habitat and food for many marine species.

Marine Flora of French Polynesia: An Updated List Using DNA Barcoding and Traditional Approaches

open access: yesBiology, 2023
Located in the heart of the South Pacific Ocean, the French Polynesian islands represent a remarkable setting for biological colonization and diversification, because of their isolation.

Exploring Components of the CO2-Concentrating Mechanism in Alkaliphilic Cyanobacteria Through Genome-Based Analysis

open access: yesComputational and Structural Biotechnology Journal, 2017
In cyanobacteria, the CO2-concentrating mechanism (CCM) is a vital biological process that provides effective photosynthetic CO2 fixation by elevating the CO2 level near the active site of Rubisco.

Symbioses of Cyanobacteria in Marine Environments: Ecological Insights and Biotechnological Perspectives

open access: yesMarine Drugs, 2021
Cyanobacteria are a diversified phylum of nitrogen-fixing, photo-oxygenic bacteria able to colonize a wide array of environments. In addition to their fundamental role as diazotrophs, they produce a plethora of bioactive molecules, often as secondary ...

Exploring Bioactive Properties of Marine Cyanobacteria Isolated from the Portuguese Coast: High Potential as a Source of Anticancer Compounds

open access: yesMarine Drugs, 2013
The oceans remain a major source of natural compounds with potential in pharmacology. In particular, during the last few decades, marine cyanobacteria have been in focus as producers of interesting bioactive compounds, especially for the treatment of ...

Global distribution and diversity of marine euendolithic cyanobacteria

open access: yesJournal of Phycology, 2022
Euendolithic, or true‐boring, cyanobacteria actively erode carbonate‐containing substrata in a wide range of environments and pose significant risks to calcareous marine fauna. Their boring activities cause structural damage and increase susceptibility to disease and are projected to only intensify with global climate change. Most research has, however,

Faster growth of the major prokaryotic versus eukaryotic CO2 fixers in the oligotrphic ocean [PDF]

open access: yes, 2014
Because maintenance of non-scalable cellular components—membranes and chromosomes—requires an increasing fraction of energy as cell size decreases, miniaturization comes at a considerable energetic cost for a phytoplanktonic cell.

Overgrowth of reef organisms by benthic cyanobacteria in the Colombian Caribbean

open access: yesMutis, 2013
Blooms of marine benthic cyanobacteria seem to be recurrent at various reef sites of the Colombian Caribbean. However, their effect on local reef communities has not been assessed.

Phanerozoic Large Igneous Province, Petroleum System, and Source Rock Links

open access: yesGeophysical Monograph Series, Page 191-228., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.
