Culture solution continuous filling method and system for chlamydomonas culture

Abstract

The invention relates to culture solution filling method and system for chlamydomonas culture. The method comprises the following steps: heating, disinfecting and cooling sea water, and then storing the sea water; mixing the sea water and a culture solution with nutritive salt in a various nutritive salt tanks, and filtering through a sand filtering device; and inputting the mixture into a chlamydomonas culture reactor through a pipeline with a quantitative control clamp. The system comprises a constant-pressure storage tank which is provided with a solution transmission pipeline, and is connected with a sea water heating and disinfecting device, and a nutritive salt tank which is used for filling the nutritive solution to the solution transmission pipeline through a pump, wherein the output end of the solution transmission pipeline is connected with the branch of a material liquid transmission pipeline on a culturing bracket through the sand filtering device, and is communicated with a hanging bag type photobioreactor, and the material liquid transmitting pipeline is arranged on a culture support. The method disclosed by the invention can realize the automatic, sterile and unwatched line production of culture solution. The system disclosed by the invention has a closing property, a systematic property, a quantitative property, a cleaning function and a buffering effect.

Description

technical field [0001] The present invention relates to a method and system for continuously filling culture fluid for algae cultivation, in particular to a method and system for continuously filling culture fluid for cultivating unicellular algae, which is suitable for continuous filling culture when cultivating unicellular algae liquid. Background technique [0002] The cultivation of algae, especially the single-celled algae, has not yet formed a scale, and most of them stay in the flask cultivation in the laboratory. During the flask cultivation process, the feed liquid is filled by using the laboratory container. There is also a small amount of culture that simply takes seawater from the sea with a bucket or other container, pours it into an open container such as a pot or bucket, and cultivates it by using an air stone to inflate it. In production, there are also a small number of earthen ponds or cement ponds, which are cultivated in the open air after adding seawate...

AI Technical Summary

Problems solved by technology

[0003] The disadvantage of the above method is that the seawater added is generally not sterilized and not filtered effectively, so it is easy to bring in impurities or bacteria, or even harmful organisms.

When adding the feed liquid in this way, the process of liquid addition is discontinuous, which will cause the instability of the culture water environment

When a large amount of water is added at one time, it will cause a greater impact on the temperature and salinity of the culture water body. Sudden changes in the culture water environment will cause a stress response or even stop growth of the unicellular algae
