Greetings and welcome, dear readers of this prestigious platform, the topic that concerns us this time is of a scientific nature and is oriented to the use of microalgae as a mechanism for capturing carbon dioxide, which causes the greenhouse effect and the environmental damage that the activity of man has been causing in his desire for development.

In this sense, we will rely on a series of investigations that have been carried out by a group of researchers belonging to the University of Almería in Madrid, where the profitability of the use of some species of algae in obtaining by-products derived from the dioxide obtained by microorganisms.

In this sense, it is not surprising that the research and use of microalgae has increased in recent years, since at an experimental level the obtaining of biomass represents a range of possibilities and applications that can give the material obtained, applications ranging from the preparation of biofuels, food additives, cosmetic preparation, among others.

Based on the above, it has been possible to identify a new quality of the species and it is focused on the alternative of carbon dioxide fixation and its transformation into oxygen through the photosynthetic process.

This as a mechanism or alternative to the objectives established by the United Nations Organization, where it is clearly stated that by 2030 we must achieve a considerable reduction in the planet's polluting gases, in such a way that Thus, achieving standardization of a process that lowers the costs of obtaining biomass and, consequently, a greater fixation of carbon dioxide, would be a great advance in terms of sustainability.

According to quantitative data, it has been possible to determine the transformation of 2 kg of carbon dioxide into oxygen from 1 kg of biomass of microalgae, values much more profitable than higher plant species .

At an experimental level, the technique is based on the use of different species of microalgae that are subjected to containers under culture conditions, which are called reactors, where the profitability and efficiency of each species is evaluated, in terms of the elaboration of by-products. refers.

Thus, through this experimental analysis technique, it has been possible to conclude that productivity depends on each species of algae used, as well as the type of reactor and pre-established experimental conditions.

Under experimental conditions it has been possible to determine that in open systems it is possible to produce an equivalent between 10 to 20 grams of biomass per square meter, which represents a fixation of carbon dioxide of more than 40 grams per square meter, however, the greatest profitability seems to be achieved in closed systems, where figures of more than 30 grams of biomass per square meter have been established, equivalent to 60 grams of dioxide fixation per meter of the algae species.

In this sense, we can observe how the environmental conditions influence the efficiency of the species, even so, being able to massify the use of the biological system would represent an alternative to the current demands to reduce the levels of carbon dioxide available in our atmosphere.

hello @madridbg,
it fills me with great joy that science is looking for alternatives to curb the advances of climate damage, in that sense using algae to produce oxygen and reduce the levels of harmful gases for the planet can be a way out in the war against climate change. in a few years when it is most needed, this kind of discoveries can save the planet.

Hello @madridbg
It seems that there are great efforts to create natural mechanisms to counteract the high levels of CO2 in the environment, to minimize all that it produces.
However, I see not so much development in decreasing the mechanisms that originate the high levels of CO2. Because they talk about electric cars, but the truth is that the production of gasoline cars is still at high levels, even the number of companies continues to increase, which are the main cause of all this problem.
But, based on what you share, it is obviously an advance and from what I see it has good effectiveness.

Hi my friend, lately microalgae have aroused much interest because of their ability to capture carbon dioxide and because they are an excellent source of biomass, something that can be very beneficial to the environment if combined with the reduction of greenhouse gas emissions through the use of green energy.
