Microalgae light fermentation culture device

Abstract

The invention discloses a microalgae light fermentation culture device in the field of microalgae culture, which mainly comprises a transparent bag with a frame, a top plate structure, a parameter detection system and a hoop, a closed bag formed by the transparent bag and the hoop of an upper cover plate is sterilized to realize sterility, then algae species are inoculated for culture, and meanwhile, the parameter detection system is connected to realize pH; the method comprises the following steps: measuring the temperature and dissolved oxygen, opening a hoop after culture is finished, taking out an algae solution, then thoroughly cleaning each part, sterilizing a film bag through one or more modes of radiation, electron beam, ethylene oxide and ultraviolet sterilization technologies, and realizing sterile culture of microalgae; furthermore because the device is made of a transparent material, external light can irradiate into the culture solution to provide light energy, so that the light fermentation culture of the microalgae is realized, the efficient culture of the microalgae is realized, meanwhile, the device is low in manufacturing cost and can be recycled, the investment and operation cost of microalgae culture are greatly reduced, and the low-cost culture of the microalgae is realized.

Description

technical field [0001] The invention relates to the field of microalgae cultivation, in particular to a microalgae photofermentation cultivation device. Background technique [0002] Microalgae is a kind of tiny algae, which is rich in protein, amino acid, unsaturated fatty acid, vitamin, polysaccharide and other nutrients and active substances. It is widely used as functional food, nutritional enhancer, feed additive, biological fertilizer and soil improver. application. At the same time, because microalgae can grow through photosynthesis, they can absorb nitrogen, phosphorus, COD and other water substances and release oxygen during the process, which has the function of water purification and is often used as a water regulator in aquatic products. In addition, marine microalgae such as diatoms are rich in unsaturated fatty acids EPA and DHA, which are often used as enhancers for biological bait and animal bait in aquatic breeding. [0003] However, due to the very slow g...

AI Technical Summary

Problems solved by technology

However, because microalgae photofermentation requires a sterilizable and transparent culture device, the usual sterilizable glass fermenter has many shortcomings such as difficulty in scaling up and high investment costs, making it difficult to carry out low-cost, large-scale cultivation

At present, there is no suitable microalgae photofermentation culture device, which greatly limits the application of microalgae photofermentation technology with obvious advantages in the field of microalgae cultivation
