Bacteria play a crucial role in aquaponic systems, converting ammonia from fish waste into nitrate, a nutrient that can be used by plants. [32] Beneficial bacteria, such as Nitrosomonas and Nitrobacter, are essential for maintaining a healthy and balanced ecosystem. Bacteria help to purify the water by removing excess ammonia and other waste ...
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]
The green scum shown in this image is the algae bloom in Lake Erie. Within aquatic ecosystems, algae assumes a pivotal role by utilizing photosynthesis to transform water and carbon dioxide into sugar, concurrently releasing oxygen as a by-product. However, inadequate management can create significant environmental consequences.
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.
Spirulina is the dried biomass of cyanobacteria (blue-green algae) that can be consumed by humans and animals. The three species are Arthrospira platensis , A. fusiformis , and A. maxima . Cultivated worldwide, Arthrospira is used as a dietary supplement or whole food . [ 1 ]
Recent studies around the world look at the algae usage for treating wastewater as a way to become more sustainable. [12] The utilization of algae as food is very common in East Asian regions [13] and is making an appearance around the world for uses in feedstock and even pharmaceuticals due to their high value products. [9]
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 ...
Single-cell proteins (SCP) or microbial proteins [1] refer to edible unicellular microorganisms.The biomass or protein extract from pure or mixed cultures of algae, yeasts, fungi or bacteria may be used as an ingredient or a substitute for protein-rich foods, and is suitable for human consumption or as animal feeds.
