Algae is an alternative for gelatin and can also be a much more natural/healthier source for creating low carb, gluten and fat-free foods. [4] Algae presents a distinct advantage over traditional food and feed sources, as it does not compete with them and does not require changes in land use.
The organisms require nutrient-rich water with temperatures between 6 and 14 °C (43 and 57 °F). They are known for their high growth rate—the genera Macrocystis and Nereocystis can grow as fast as half a metre a day (that is, about 20 inches a day), ultimately reaching 30 to 80 metres (100 to 260 ft).
Algae can be used to capture fertilizers in runoff from farms. When subsequently harvested, the enriched algae can be used as fertilizer. 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. [130] [131]
Chara is a genus of charophyte green algae in the family Characeae. They are multicellular and superficially resemble land plants because of stem -like and leaf -like structures. They are found in freshwater, particularly in limestone areas throughout the northern temperate zone, where they grow submerged, attached to the muddy bottom.
Seaweed is lifted out of the top of an algae scrubber/cultivator, to be discarded or used as food, fertilizer, or skin care. Alginates are used in industrial products such as paper coatings, adhesives, dyes, gels, explosives and in processes such as paper sizing, textile printing, hydro-mulching and drilling.
Monocots are grass and grass-like flowering plants (angiosperms), the seeds of which typically contain only one embryonic leaf or cotyledon. [12] Terrestrial plants evolved perhaps as early as 450 million years ago from a group of green algae. [13] Seagrasses then evolved from terrestrial plants which migrated back into the ocean.
The presence of mucilage in seeds affects important ecological processes in some plant species, such as tolerance of water stress, competition via allelopathy, or facilitation of germination through attachment to soil particles. [13] [14] [15] Some authors have also suggested a role of seed mucilage in protecting DNA material from irradiation ...
A large number of Phaeophyceae are intertidal or upper littoral, [26] and they are predominantly cool and cold water organisms that benefit from nutrients in up welling cold water currents and inflows from land; Sargassum being a prominent exception to this generalisation. Brown algae growing in brackish waters are almost solely asexual. [26]
