Today, algae are used by humans in many ways; for example, as fertilizers, soil conditioners, and livestock feed. [123] Aquatic and microscopic species are cultured in clear tanks or ponds and are either harvested or used to treat effluents pumped through the ponds. Algaculture on a large scale is an important type of aquaculture in some places.
Algae is an alternative for gelatin and can also be a much more natural/healthier source for creating low carb, gluten and fat-free foods. [ 4 ] Algae presents a distinct advantage over traditional food and feed sources, as it does not compete with them and does not require changes in land use.
The researcher behind this outlined the benefits of using this food replacement for chickens in that it improved growth and wellbeing of the chicken. While this example is not a natural one, it does outline the use of algae as a food source for domestic chickens, an important consideration in the future of both algophagy and agriculture.
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 ...
The food industry exploits the gelling, water-retention, emulsifying and other physical properties of these hydrocolloids. [6] Most edible seaweeds are marine algae whereas most freshwater algae are toxic. Some marine algae contain acids that irritate the digestion canal, while others can have a laxative and electrolyte-balancing effect. [7]
So how does algae become biodiesel? Garton explained the algae has to be grown and cultivated. Afterwards, oil must be extracted from the algae, which can be further refined and turned into biodiesel.
Four of the City of Lake Geneva's beaches remain closed due to blue-green algae, a bloom that can produce toxins that can make humans and animals sick, or even cause them to die in some cases.
Therefore, exopolysaccharide-producing "soil algae" play a vital role in the ecology of the world's soils. The substance covers the outside of, for example, unicellular or filamentous green algae and cyanobacteria. Amongst the green algae especially, the group Volvocales are known to produce exopolysaccharides at a certain point in their life ...
