Example Embodiment
[0099] Example 1
[0100] The hollow tubular body used in Example 1 is made of polypropylene material, the outer diameter of the polypropylene hollow tubular body is 2 mm, the inner diameter is 1 mm, and the pore diameter of the polypropylene hollow tubular body is 0.005-0.01 Micron, the microalgae used for inoculation is Pseudochlorococcus with a concentration of 10% algal liquid, and the cell diameter is 2-6 mm.
[0101] 1. Inoculation:
[0102] Put the polypropylene hollow tubular body 1 into the algae liquid pool with the algae liquid concentration of 10%, see Figure 5 , open the decompression pump 8 and the third valve 43, so that the pressure in the polypropylene hollow tubular body 1 is 0.1-0.6 MPa, and the culture solution in the algae pond enters through the pores on the polypropylene hollow tubular body 1. The polypropylene hollow tubular body 1 is evacuated by the decompression pump 8, and the algal cells in the algae liquid pool are blocked outside the polypropy...
Example Embodiment
[0109] Example 2
[0110] The hollow tubular body used in Example 2 is made of ceramic material through a sintering process, the pore diameter is in the range of 0.01-0.5 microns, and the microalgae used for inoculation are Pseudo-Nicochlorous algae with an algal liquid concentration of 10%, Cells are 2-6 mm in diameter.
[0111] 1. Inoculation:
[0112] Put the ceramic hollow tubular body 1 into the algae liquid pool with the algae liquid concentration of 10%, see Figure 5 , open the decompression pump 8 and the third valve 43, so that the pressure in the ceramic hollow tubular body is 0.1-0.6MPa, and the culture solution in the algae pond enters the ceramic hollow through the pores on the ceramic hollow tubular body 1. Inside the tubular body 1, and is evacuated by the decompression pump 8, and the algal cells in the algae liquid pool are blocked outside the ceramic hollow tubular body 1, attached to the immobilized culture surface, and the thickness of the algal cells af...
Example Embodiment
[0119] Experimental example:
[0120] In order to objectively evaluate the cell shedding and microalgae cultivation of the Examples 1-2, the specific experiments will be described in detail below.
[0121] 1. Test sample
[0122] The culture solution that fell into the collection tank 5 and the microalgae after the harvesting was completed during the immobilized cultivation process in the control example and Example 1-2.
[0123] 2. Test analysis method:
[0124] The OD value at the wavelength of 750nm was measured by a spectrophotometer, that is, the concentration of algal fluid.
[0125] 3. Experimental results:
[0126] Referring to Table 1, it is the OD value of the algal liquid concentration of the culture liquid flowing through the immobilized cultivation surface during the immobilized cultivation process of the control example and Examples 1-2.
[0127] Table 1
[0128]
[0129] Referring to Table 1, we found that: when the immobilized cultivation devic...
