Aquaria and ponds can be filtered using algae, which absorb nutrients from the water in a device called an algae scrubber, also known as an algae turf scrubber. [ 129 ] [ 130 ] Agricultural Research Service scientists found that 60–90% of nitrogen runoff and 70–100% of phosphorus runoff can be captured from manure effluents using a ...
Green, red and brown algae all have multicellular macroscopic forms that make up the familiar seaweeds. Green algae , an informal group, contains about 8,000 recognised species. [ 49 ] Many species live most of their lives as single cells or are filamentous, while others form colonies made up from long chains of cells, or are highly ...
This vast air–water interface sits at the intersection of major air–water exchange processes spanning more than 70% of the global surface area . Bacteria in the surface microlayer of the ocean, called bacterioneuston , are of interest due to practical applications such as air-sea gas exchange of greenhouse gases, production of climate ...
Vents can be characterized by temperature and chemical composition as diffuse vents which release clear relatively cool water usually below 30 °C, as white smokers which emit milky coloured water at warmer temperatures, about 200-330 °C, and as black smokers which emit water darkened by accumulated precipitates of sulfide at hot temperatures ...
Chlorophyta (green algae), mostly unicellular algae found in fresh water. [44] The chlorophyta are of particular importance because they are believed to be most closely related to the evolution of land plants. [45] Diatoms, unicellular algae that have siliceous cell walls. [46] They are the most abundant form of algae in the ocean, although ...
Microalgae or microphytes are microscopic algae invisible to the naked eye. They are phytoplankton typically found in freshwater and marine systems, living in both the water column and sediment. [1] They are unicellular species which exist individually, or in chains or groups. Depending on the species, their sizes can range from a few ...

Nannochloropsis is a genus of algae comprising six known species.The genus in the current taxonomic classification was first termed by Hibberd (1981). [2] The species have mostly been known from the marine environment but also occur in fresh and brackish water. [3]
