Ascophyllum nodosum is an autotroph, meaning that it makes its own food by photosynthesis, like other plants and algae. The air bladders on A. nodosum serve as a flotation device, which allows sunlight to reach the plant better, aiding photosynthesis. [6] Epiphytic red algae on knotted wrack at Roscoff, France
Grossman is an expert in algal photosynthesis and has studied how algae protect themselves from harsh environments and reasoned they could be used to protect human skin. [25] TerraVia also markets its AlgaPūr Algae Oil brand to personal care producers. Unilever, a leading consumer goods company, is one of TerraVia's biggest partners.
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 ...
Pelvetia canaliculata, the channelled wrack, [2] is a very common brown alga (Phaeophyceae) found on the rocks of the upper shores of Europe. It is the only species remaining in the monotypic genus Pelvetia .
Iran started investigating the production of algae from 2000. Scientific evidence shows that south Iran is the richest area in the world for cultivating algae, because of high humidity, sunny weather, large unused area and salty water. [2] The first version of algae based biofuel will become available for industrial purposes in 2015. [3]
Algae can be converted into various types of fuels, depending on the production technologies and the part of the cells used. The lipid, or oily part of the algae biomass can be extracted and converted into biodiesel through a process similar to that used for any other vegetable oil, or converted in a refinery into "drop-in" replacements for petroleum-based fuels.
Algae fuel, algal biofuel, or algal oil is an alternative to liquid fossil fuels that uses algae as its source of energy-rich oils. Also, algae fuels are an alternative to commonly known biofuel sources, such as corn and sugarcane. [50] [51] When made from seaweed (macroalgae) it can be known as seaweed fuel or seaweed oil.
Wrack line on a sandy beach adjacent to a sand dune ecosystem. Beach wrack or marine wrack is organic material (e.g. kelp, seagrass, driftwood) and other debris deposited at high tide on beaches and other coastal area. This material acts as a natural input of marine resources into a terrestrial system, providing food and habitat for a variety ...
