The active release of reactive oxygen species from cells has a variety of purposes, including a means to deter predators, or a chemical defense for the incapacitation of competitors. [ 58 ] [ 59 ] [ 60 ] In addition, ROS may be involved in cell signaling, as well as the oxidation or reduction of necessary or toxic metals.
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 ...
Microalgae play a major role in nutrient cycling and fixing inorganic carbon into organic molecules and expressing oxygen in marine biosphere. While fish oil has become famous for its omega-3 fatty acid content, fish do not actually produce omega-3s, instead accumulating their omega-3 reserves by consuming microalgae. These omega-3 fatty acids ...
“When the algae die and break down, they create oxygen-depleted dead zones in the water where fish, crabs, oysters, and other aquatic life cannot survive,” the bay foundation said in a statement.
Climate change is going to wreak havoc on the world’s oceans, according to two new studies, depleting the warming waters of the oxygen that fish and other sea life need to survive.
Cyanobacteria (blue-green algae) bloom on Lake Erie (United States) in 2009. These kinds of algae can cause harmful algal bloom. A harmful algal bloom (HAB), or excessive algae growth, sometimes called a red tide in marine environments, is an algal bloom that causes negative impacts to other organisms by production of natural algae-produced toxins, water deoxygenation, mechanical damage to ...
The organisms responsible for primary production are called primary producers or autotrophs. Most marine primary production is generated by a diverse collection of marine microorganisms called algae and cyanobacteria. Together these form the principal primary producers at the base of the ocean food chain and produce half of the world's oxygen ...
Through a series of chemical reactions, the microbes were able to break down soluble compounds called nitrites, molecules made of one nitrogen and two oxygen atoms, to produce molecular oxygen in ...
