Commercial and industrial algae cultivation has numerous uses, including production of nutraceuticals such as omega-3 fatty acids (as algal oil) [97] [98] [99] or natural food colorants and dyes, food, fertilizers, bioplastics, chemical feedstock (raw material), protein-rich animal/aquaculture feed, pharmaceuticals, and algal fuel, [100] and ...
Algae primarily use three different types of spores for asexual reproduction - autospores, zoospores, and aplanospores. [3] Autospores occur in several groups of algae, including Eustigmatophyceae, Dinoflagellates, and green algae. One example of a colonial alga that produces autospores is Dichotomococcus.
The algal symbionts convert inorganic carbon into carbohydrates for use by each partner and release oxygen to the animal host in the process. To accommodate the algae, the anemone must provide concentrated carbon dioxide to their intracellular photosynthetic guests as well as photosynthetically active radiation (PAR) to fuel the photosynthetic ...
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 ...
Harmful Algal blooms are colonies of microscopic algae that grow out of control. They can be damaging to people, wildlife and the environment. How harmful algal blooms, or colonies of microscopic ...
The most common, conventional extraction process involves six steps: pre-treatment of the algal biomass, acid treatment, alkaline extraction, precipitation, bleaching, and drying. [4] Pre-treatments mainly aim at either breaking the cell wall to help extract the alginate, or removing other compounds and contaminants from the algae. [4]
In lotic habitats (rivers, streams), golden algae (Chrysophyceae) and yellow-green algae (Xanthophyceae) are common and occasionally abundant. The golden algal genus Hydrurus , in particular, can be widespread in some drainage basins and is common in cold, clear, fast-flowing mountain streams, where it attaches to a firm substrate.
Microalgae or microphytes are microscopic algae invisible to the naked eye. They are phytoplankton typically found in freshwater and marine systems, living in both the water column and sediment. [1] They are unicellular species which exist individually, or in chains or groups. Depending on the species, their sizes can range from a few ...
