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 ...
Dulse is one of many edible algae. Algaculture may become an important part of a healthy and sustainable food system [11]. Several species of algae are raised for food. While algae have qualities of a sustainable food source, "producing highly digestible proteins, lipids, and carbohydrates, and are rich in essential fatty acids, vitamins, and minerals" and e.g. having a high protein ...
Ulvaria obscura is a common marine algae, typically identified in algal blooms referred to as "Green Tides". [3] [4] The species is distinct in its ability to produce the neurotransmitter dopamine as a herbivore defense mechanism.
Valonia ventricosa, also known as bubble algae, sea grape, [2] or sailor's eyeballs, [3] is a species of algae found in oceans throughout the world in tropical and subtropical regions, within the phylum Chlorophyta. It is one of the largest known unicellular organisms. [3] [4] Valonia ventricosa in the Red Sea
Volvox is a polyphyletic genus of chlorophyte green algae in the family Volvocaceae. Volvox species form spherical colonies of up to 50,000 cells, and for this reason they are sometimes called globe algae. They live in a variety of freshwater habitats, and were first reported by Antonie van Leeuwenhoek in 1700.
Laurencia can be found all over the world, in particular in tropical and subtropical regions with warmer waters. [citation needed] Its habitats range from tide pools, reef flats, mud flats, and a variety of hard substrates (e.g. rocks, corals), within intertidal and subtidal zones up to 65 m. [4]
The algae poses a threat to both marine and human life. People should avoid swimming in water around the blooms because toxins that may be present could lead to a host of illnesses.
Scenedesmus is one of the most common freshwater algae genera; however, the extremely diverse morphologies found within species make identification difficult. [4] While most species are found across the world, certain species exist only in local populations such as S. intermedius and S. serratus which are found in New Zealand.
