Description

Microalgae culture system {Microalgae culture system}

The present invention relates to a microalgae culture system.

Microalgae are single-celled photosynthetic organisms that live in the sea or fresh water and are commonly called phytoplankton. These are very common organisms that are widely distributed throughout the Earth, making up the bottom layer of the food chain in the marine ecosystem.

The reason why these common microalgae have recently received great attention in relation to the development of alternative energy is because of their characteristics. The first characteristic of microalgae is that they divide very easily through cell division, allowing their population to increase explosively.

Although corn or sugarcane, which are the main raw materials for biofuel, cannot double their production in a short period of time, single-celled microalgae can divide rapidly and increase their population several times a day as long as the surrounding environment, such as water temperature and nutrients, is right. there is.

The second characteristic is that microalgae do not need tissues such as stems or roots like ordinary plants, so all cells can participate in photosynthesis. The fact that all cells undergo photosynthesis means that it is more advantageous for biomass production, so the amount of biofuel obtained from microalgae when cultivated in the same area is much greater than that obtained from plants such as corn or soybeans.

Lastly, the third characteristic of microalgae is that they do not incur opportunity costs because they do not need to be cultivated in agricultural land. There is no possibility of being embroiled in controversy over turning valuable food into fuel, like biofuels using current crop resources, and because it is underwater, there is no need to occupy land where other crops would grow.

For the above-mentioned reasons, research and development on systems or devices for cultivating microalgae is being actively conducted. Korean Patent No. 10-2402489 discloses a microalgae culture device.

However, the microalgae culture device disclosed in Korean Patent No. 10-2402489 has the disadvantage of being bulky because the culture units are arranged in a row, and that the user must operate it manually to obtain cultured microalgae. do. In addition, as air is supplied to the culture unit using an air pump, there is a problem in that the culture medium does not flow smoothly because the air occupies a certain volume in the culture unit.

Accordingly, recently, research has been actively conducted on microalgae cultivation systems or devices that allow users to conveniently cultivate and obtain microalgae. In addition, research is being actively conducted to solve the problem of culture media or water not flowing smoothly due to air filling the culture tube during cultivation.
