After inoculation, seal the Erlenmeyer flask with an oxygen-permeable sealing film, and place it under a 60W incandescent light to stand still or shake it on a shaker for cultivation. The light intensity is controlled at 3000lux, and the temperature is controlled at 26-30°C. The finished bacteria can be obtained after culturing for 2 to 3 days.
上述培养过程中,菌体生长情况如图2所示,由图2可以看出,本发明培养基培养的光合细菌的浓度高,OD660高达2.2,达到甚至超过RCVBN培养基所得的菌体浓度(为1.8左右,其培养方案与本发明培养基的培养方案相同)。In the above-mentioned cultivation process, the thalline growth situation is as shown in Figure 2, as can be seen from Figure 2, the concentration of photosynthetic bacteria cultivated in the medium of the present invention is high, and OD660 is up to 2.2, reaching or even surpassing the thalline concentration of RCVBN medium gained (being about 1.8, its culture scheme is identical with the culture scheme of culture medium of the present invention).
