The main importance of algae in nature and human life. Application in various industries and agriculture.


It is impossible to overestimate the importance of algae in nature and human life. Thanks to the processes of photosynthesis, they are the main producers of a huge amount of organic matter in fresh and saline water bodies. Special attention should be paid to the fact that algae intensively produce oxygen in water, which is so necessary for river and sea inhabitants. A man has long appreciated these plants for their dignity and has found application in many industries and in agriculture.

The value of algae in nature and human life


Perhaps the most important function that absolutely all types of algae perform is the absorption of carbon dioxide from water. In exchange, they release oxygen, without which it is impossible to imagine the life of modern plants and animals. Equally important is the participation of algae in the circulation of substances on the planet. Its cyclical nature allows all types of living beings to exist on earth for more than one thousand years. In addition, algae - the main source in the reservoirs of organic matter, which are an excellent food supply. A huge number of animals depend on it. Equally important is the evolutionary significance of algae. They significantly influenced not only the composition of the Earth’s atmosphere, but also the formation of its relief. In addition, these plant organisms (both single-celled and multicellular) play a significant role in the self-purification of rivers, lakes and ponds, as well as sewage. Algae, especially their unicellular representatives, are an excellent indicator of salinization and pollution of the reservoir. But they live not only in water, but also in the soil. Participating in the circulation of silicon and calcium, they actively enrich the earth with these components.

The importance of algae in agriculture


The great importance of algae in nature and human life is explained by their ability to produce organic matter. Therefore, they are widely used in the perfumery, food, pharmaceutical industry. But even more of them are used in agriculture. In developed countries, fertilizers are made on the basis of algae. If you spray them with saplings of tomatoes, peppers, eggplant and melon crops, then they not only grow faster, but also give a great harvest. In addition to vegetable farming, algae penetrated into livestock. Cows, geese, chickens, ducks become more productive with a particularly balanced diet. Organic algae components are introduced into the food of farm animals.

The value of algae in the food industry


Every year on all continents of the planet, people eat several billion tons of processed algae. First of all, we are talking about sea kale. It refers to the brown algae. It contains a huge amount of nutrients and, importantly, nutrients. These are iodine compounds and calcium, which is necessary for normal metabolism. The importance of algae in nature and human life is simply enormous. The cultivation of marine and freshwater crops gives very encouraging results. They are increasingly used in the food industry. For example, Japanese cuisine uses algae flour when baking bread. And this is the main product on the table in every family. Algae are added to puddings, cakes and even ice cream. Recently, their application during conservation is no less relevant. In many countries every year more and more cafes are opened, where you can order various dishes exclusively from seaweed.

Unicellular algae and their importance in astronautics


Oddly enough, but just a simple unicellular alga Chlorella is assigned a huge role in modern astronautics. It is able to produce a large amount of oxygen. In this, almost all plant species are inferior to it. It is important that it has microscopic dimensions, which means it does not take up much space. She has a short growing season and a very high reproduction rate. All chlorella biomass obtained can be used at orbital stations not only for oxygen production, but also as food. Her nutritional qualities are really impressive. The protein content in chlorella is at least 50 percent of the dry weight. In addition, this algae contains amino acids and vitamins necessary for human life. All this makes the use of chlorella in space flights very promising.

The use of algae in microbiology

Great variety and value of algae. They have found their use even in microbiology. From the brown and red algae produce the substance agar-agar. It can freeze at room temperature and turn into a jelly. It is this property that became decisive in the choice between gelatin and agar in the production of nutrient media for the cultivation of microorganisms. This substance has good nutritional properties and does not melt in a thermostat. Therefore, at present all artificial nutrient media are prepared on the basis of agar.

Algae use for wastewater treatment


In recent years, the importance of algae has increased in human life in the communal and domestic sphere. They are cultivated in industrial wastewater in order to activate the processes of self-purification. In the future, excess organic mass will be used to produce methane, which is planned to be used in agricultural and industrial production. Chlamydomonas can do best with pollution. She is able to choose from organic matter water, cleansing it.
