Embodiment 1
[0009] Example 1. This example improves Pseudochlorococcum ( N.salina ) The specific steps of the cultivation method of carbon sequestration and oil production capacity are as follows:
[0010] 1. Cultivation of microalgae: Pseudochlorococcum N.salina Inoculated into three Erlenmeyer flasks containing f / 2 medium, with an initial pH of 8 and a temperature of 23-27 o C, light 65~95μmolm -2 s -1 . Nutrient-rich f / 2 medium, each liter contains: 33.6g artificial sea salt, 0.075g NaNO 3 , 0.00565gNaH 2 PO 4 ·2H 2 O, 1ml trace elements (T) and 1ml vitamins. Among them, each liter of trace element T contains: 4.16gNa 2 EDTA, 3.15gFeCl 3 ·6H 2 O, 0.18gMnCl 2 ·4H 2 O, 10mgCoCl 2 ·6H 2 O, 10mgCuSO 4 ·5H 2 O, 22mgZnSO 4 ·7H 2 O, 6mgNa 2 MoO 4 ·2H 2 O. Each liter of vitamins contains: 100mg vitamin B1, 0.5mg vitamin B12 and 0.5mg vitamin H.
[0011] 2. The supply of carbon dioxide: to three pseudochlorococcum N.salina Air with different concentrations of carbon dioxide is introduced into the c...
