Asparagopsis taxiformis (red sea plume or limu kohu), formerly A. sanfordiana, [1] is a species of red algae, with cosmopolitan distribution in tropical to warm temperate waters. [2] Researchers have demonstrated that feeding ruminants a diet containing 0.2% A. taxiformis seaweed reduced their methane emissions by nearly 99 percent.
Most algae are harmless, LCRA officials said, but some species — notably cyanobacteria or blue-green algae — can produce toxins that can be dangerous to animals and people. Lake safety for pets
The addition of nitrogen and phosphorus can cause the rapid growth of algae, also known as an algae bloom. The reduction of oxygen and nutrients in the water caused by the growth of algae ultimately leads to the death of other species in the ecosystem. This ecological harm has consequences not only for the native animals in the affected water ...
Maerl has been extracted for centuries mainly for use as an agricultural fertilizer. The amount extracted increased in the late 20th century and in 2000, maerl was extracted at c. 5,000 tonnes per year in Ireland and c. 500,000 tonnes per year in France. [19] Large scale maerl extraction over the past 40 years has removed and degraded maerl ...
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, is an algal bloom that causes negative impacts to other organisms by production of natural algae-produced toxins, water deoxygenation, mechanical damage to other organisms, or by other means.
Red algae, like Gracilaria, Gelidium, Euchema, Porphyra, Acanthophora, and Palmaria are primarily known for their industrial use for phycocolloids (agar, algin, furcellaran and carrageenan) as thickening agent, textiles, food, anticoagulants, water-binding agents, etc. [87] Dulse (Palmaria palmata) is one of the most consumed red algae and is a ...
Chondrus crispus—commonly called Irish moss or carrageenan moss (Irish carraigín, "little rock")—is a species of red algae [1] which grows abundantly along the rocky parts of the Atlantic coasts of Europe and North America. In its fresh condition it is soft and cartilaginous, varying in color from a greenish-yellow, through red, to a dark ...
Galdieria is a genus of red algae belonging to the order Galdieriales; [1] family Galdieriaceae. [2] It was created by an Italian botanist Aldo Merola in 1981 for the identification from the species of Cyanidium. [3] [4] Species: [2] Galdieria daedala O.Yu.Sentsova, 1991; Galdieria maxima O.Yu.Sentsova, 1991; Galdieria partita O.Yu.Sentsova, 1991
