Microalgae are used in various biotechnological processes, such as biofuel production due
to their high biomass yields, agriculture as biofertilizers, production of high-value-added …

Biological dinitrogen (N 2) fixation is a key metabolic process exclusively performed by
prokaryotes, some of which are symbiotic with eukaryotes. Species of the marine haptophyte …

In the open ocean, some phytoplankton establish symbiosis with cyanobacteria. Some
partnerships involve diatoms as hosts and heterocystous cyanobacteria as symbionts …

Sponges have co-evolved with microbes for over 400 myr. Previous studies have
demonstrated that sponges can be classified according to the abundance of microbes in …

The rapid growth of diatoms makes them one of the most pervasive and productive types of
plankton in the world's ocean, but the physiological basis for their high growth rates remains …

Nitrogen fixers (diazotrophs) are often an important nitrogen source to phytoplankton
nutrient budgets in N-limited marine environments. Diazotrophic symbioses between …

N2 fixation constitutes an important new nitrogen source in the open sea. One group of
filamentous N2 fixing cyanobacteria (Richelia intracellularis, hereafter Richelia) form …

Nitrogen-fixing organisms are of importance to the environment, providing bioavailable
nitrogen to the biosphere. Quantitative models have been used to complement the …

Elevated organic matter (OM) export flux promotes marine anoxia, thus increasing carbon
sequestration efficiency and decreasing atmospheric carbon dioxide levels. However, the …

Many organisms have formed symbiotic relationships with nitrogen (N)-fixing bacteria to
overcome N limitation. Diatoms in the family Rhopalodiaceae host unicellular, N-fixing …
