An algae bioreactor is used for cultivating micro or macroalgae. Algae may be cultivated for the purposes of biomass production (as in a seaweed cultivator ), wastewater treatment , CO 2 fixation , or aquarium/pond filtration in the form of an algae scrubber . [ 1 ]
The algae supply nutrients produced via photosynthesis to the Hydra. Because the algae live in the vacuoles of the cells, they are protected from the digestive enzymes of the Hydra. [3] During long period of darkness, such as storms or blooms that block sunlight, algae loss starts from the tentacles, hypostome and growth region.
In a reversal of the pattern on land, in the oceans, almost all photosynthesis is performed by algae and cyanobacteria, with a small fraction contributed by vascular plants and other groups. Algae encompass a diverse range of organisms, ranging from single floating cells to attached seaweeds. They include photoautotrophs from a variety of groups.
Green thread algae is common in newly established aquaria and is easily outcompeted by installed plants. [9] Hair algae is very similar to green thread algae. Typically, hair algae grows in a carpet of dense, short filaments. Oedogonium in particular may be referred to as hair algae. Hair algae may be caused by too much light in the aquaria. [11]
Together they carry out the primary photochemistry of photosynthesis: the absorption of light and the transfer of energy and electrons. Photosystems are found in the thylakoid membranes of plants, algae, and cyanobacteria. These membranes are located inside the chloroplasts of plants and algae, and in the cytoplasmic membrane of photosynthetic ...
The origin of the chloroplasts from green algae is supported by their pigmentation, which includes chlorophylls a and b, and by genetic similarities. The only other groups of algae that contain nucleomorphs are a few species of dinoflagellates , which also have plastids originating from green algae, [ 6 ] and the cryptomonads , which acquired ...
These algae photosynthesize and produce nutrients, some of which are passed to the coral. The coral in turn will emit ammonium waste products which the algae uptake as nutrients. There has been an observed tenfold increase in calcium carbonate formation in corals containing algal symbionts compared with corals that do not have this symbiotic ...
Gutweed or Tube algae is common in both tropical and temperate waters. The algae forms tube-like blades secured by a single holdfast to hard surfaces and Mangrove roots. In the aquarium, this algae should be kept in water temperatures under 80 °F (26.7 °C) and may be used to feed herbivorous fish.
