  2. Algaculture - Wikipedia

    en.wikipedia.org/wiki/Algaculture

    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 ...

  3. Algal nutrient solution - Wikipedia

    en.wikipedia.org/wiki/Algal_nutrient_solution

    Sometimes referred to as "Growth Media", nutrient solutions (e.g., the Hoagland solution, along with carbon dioxide and light), provide the materials needed for algae to grow. Nutrient solutions, as opposed to fertilizers, are designed specifically for use in aquatic environments and their composition is much more precise. [2]

  4. Iron fertilization - Wikipedia

    en.wikipedia.org/wiki/Iron_fertilization

    Iron is a trace element necessary for photosynthesis in plants. It is highly insoluble in sea water and in a variety of locations is the limiting nutrient for phytoplankton growth. Large algal blooms can be created by supplying iron to iron-deficient ocean waters. These blooms can nourish other organisms.

  5. Biofertilizer - Wikipedia

    en.wikipedia.org/wiki/Biofertilizer

    Blue-green algae is used as a biofertilizer. A biofertilizer is a substance containing living micro-organisms which, when applied to seeds, plant surfaces, or soil, colonize the rhizosphere or the interior of the plant and promotes growth by increasing the supply or availability of primary nutrients to the host plant. [1]

  6. Algae bioreactor - Wikipedia

    en.wikipedia.org/wiki/Algae_bioreactor

    Specifically, algae bioreactors can be used to produce fuels such as biodiesel and bioethanol, to generate animal feed, or to reduce pollutants such as NO x and CO 2 in flue gases of power plants. Fundamentally, this kind of bioreactor is based on the photosynthetic reaction, which is performed by the chlorophyll -containing algae itself using ...

  7. Algae - Wikipedia

    en.wikipedia.org/wiki/Algae

    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. [129] [130]

  8. Seaweed - Wikipedia

    en.wikipedia.org/wiki/Seaweed

    "Seaweed" lacks a formal definition, but seaweed generally lives in the ocean and is visible to the naked eye. The term refers to both flowering plants submerged in the ocean, like eelgrass, as well as larger marine algae. Generally, it is one of several groups of multicellular algae; red, green and brown. [7]

  9. Ocean fertilization - Wikipedia

    en.wikipedia.org/wiki/Ocean_fertilization

    Urea is the most used fertilizer in the world, due to its high content of nitrogen, low cost and high reactivity towards water. [32] When exposed to ocean waters, urea is metabolized by phytoplankton via urease enzymes to produce ammonia. [33] + +
