Description

Tubular-type Apparatus for Cultivating Spirulina sp.
The present invention relates to a tubular spirulina culture apparatus. More specifically, the present invention relates to a tubular spirulina culturing apparatus capable of circulating spirulina by providing a culture pipe and a pump in a conventional spirulina culturing apparatus.
Currently, agricultural crops that are cultivated all over the world have been used as a major food source for mankind, but the yield per farm area is not high and the utilization of solar energy is extremely low. On the other hand, micro photosynthetic algae, which can grow in water with inorganic energy containing solar energy, carbon dioxide, and small amounts, can grow even in areas where crops cannot be grown, and can obtain more than 20 times more protein per acreage area than crops. In addition, it is possible to produce a variety of useful substances and natural rare substances that cannot be produced from microorganisms or plant cells. In particular, algae with large cell size can be easily settled and can be extracted and separated by various methods, and by using solar energy as a main energy support, it is possible to efficiently use solar energy irradiated on the earth and carbon dioxide as a carbon source. It has a function of lowering air pollution because it has a photosynthetic process that uses oxygen and releases oxygen as a by-product.
Accordingly, the fine photosynthetic algae of the genus Chlorella, the genus Dunaliella, the genus Spirulina, and among them, the genus Spirulina sp. (Hereafter referred to as 'spirulina' for convenience) are different. Compared to micro photosynthetic algae, algae have a larger cell size and are easily grown in an alkaline contaminated environment, and are being applied to various products such as food, medicine, and industrial products, and research is being actively conducted. On the other hand, because of the climatic characteristics of the four seasons and the seasonal temperature change and the difference in the amount of sunshine, technology related to indoor culture rather than outdoor culture of spirulina has been developed.
For example, Patent No. 235182 discloses a culture tank equipped with an automatic regulating heater and a venting device, a support frame provided with equipment for supporting the culture tank, a pipe for supplying culture water to the side of the support frame, A chain culture apparatus including a rubber tube for circulating culture water and a water pump for circulating culture water is disclosed, and Patent Registration No. 609736 discloses a culture vessel in a double cylindrical shape consisting of an inner passage and an outer passage arranged horizontally, A microalgal culturing apparatus is disclosed in which at least an outer cylinder is made of a transparent material that transmits visible light, and a gas inlet is opened in a lower portion of a culture vessel. Disclosed is a channel-type microalgal outdoor culture tank which is integrally installed inside a mass culture tank for algae culture. However, when spirulina is cultivated using these incubators, the spirulina grown on the surface of the incubator is excessively adhered, resulting in a decrease in culture efficiency over time, and contaminated microorganisms. There was a downside to not getting it.
In order to overcome these problems, a technique has been developed to seal the culture tank and to provide a filter to the incoming air to prevent contamination of various bacteria. For example, Japanese Patent Application Laid-Open No. 2002-0057882 discloses a microalgae outdoor bulk culture device including an air filtration and ultraviolet sterilization device, an air pump, a filtration device, a guide tube, a filter, a needle valve, and an incubator. No. 420492 discloses a high density culture apparatus for microalgae comprising a culture tank including a lid at the top and a pH sensor and a disperser therein, a culture tank including a fluorescent lamp, a pH regulator, an air pump, and a carbon dioxide culture tank. have. However, it was possible to prevent contamination of various bacteria by using the above-described apparatus, but the problem that the cultivation efficiency decreases over time due to excessive fixation of spirulina grown on the surface of the culture apparatus has not been solved. to be.
If the spirulina grown on the surface of the culture apparatus can be solved, the swelling of the spirulina excessively increased, the cultivation efficiency of the spirulina is expected to be significantly increased, it is expected to produce spirulina more economically, but no results have been reported so far. .
Accordingly, the present inventors have made diligent research efforts to solve the problem of excessive spirulina proliferating on the surface of the culture apparatus, and devised a tubular spirulina culture apparatus equipped with a culture pipe and a pump in a conventional spirulina culture apparatus, and using the same When the spirulina is cultivated in a circulating manner, the area of spirulina culture is exposed to light is maximized, and the culture medium is circulated to confirm that the spirulina grown on the surface of the culture apparatus is not excessively fixed. It was completed.
After all, the main object of the present invention is to provide a tubular spirulina culture apparatus comprising a culture piping and a pump.
By using the tubular spirulina culturing apparatus of the present invention, it is possible to prevent the spirulina from sticking to the surface of the cultivation apparatus, thereby increasing the cultivation efficiency of spirulina, and thus will be widely used for the production of more economic spirulina.
The present inventors carried out various studies to determine the cause of excessive spirulina adhered to the surface of the culture apparatus in culturing spirulina. As a result, two causes of excessive fixation of spirulina were identified. One is that culturing spirulina is accompanied by regular conditions of bright and dark conditions, accompanied by growth of spirulina as well as growth of spirulina. , The other is that the flow of the culture solution in the culture of spirulina is limited so that the adhesion of spirulina begins at the site where the flow rate of the culture fluid is low, and the fixed area is expanded therefrom.
In order to eliminate the cause, the present inventors intended to reduce the growth rate of the spirulina population by giving only bright conditions in the culture of spirulina, and to devise a culture apparatus capable of sufficiently flowing the culture fluid, but in the form of a culture tank equipped with a stirrer. In the case of using a spirulina incubator, it was confirmed that the culture medium could not be sufficiently flowed even by increasing the stirring speed of the stirrer.
Accordingly, in order to flow the culture solution containing spirulina in a manner other than using a stirrer, it was confirmed that the culture medium can be sufficiently flowed than the method using a stirrer when the culture medium itself is circulated. In order to implement this, a spirulina cultivation apparatus having a tubular spirulina having a culture pipe and a pump with a light source attached to a conventional spirulina incubator has been devised. The tubular spirulina culture apparatus, unlike the conventional spirulina culture apparatus, it is possible to flow the culture medium by circulating the culture medium at a constant speed using a culture pipe and a pump, it is attached in the longitudinal direction along the culture pipe By using a light source, it was possible to easily provide bright conditions to the culture solution and to supply a sufficient amount of sunshine during the culture of spirulina.
