Example Embodiment
[0047] Example 1
[0048] In order to investigate the effect of different bacterial ages on the algaelytic effect of XXG strain, 5.6 mL of XXG bacterial suspension in the lag phase, logarithmic phase, and stable phase was inoculated into 100 mL of Chl-a with a concentration of 1294.22 μg / L. After 6 days of shaking culture in the Erlenmeyer flask of cystic algae liquid, the algae lysis rates were 40.28%, 50.13% and 47.19% respectively. It can be seen that the algaelytic effect of the strain in the log phase is better than that of the strain in other periods (see image 3 ).
Example Embodiment
[0049] Example 2
[0050] In order to investigate the effect of different concentrations of Microcystis aeruginosa liquid on the algaelytic effect of XXG strain, 5.6mL of XXG bacterial suspension in the logarithmic growth phase was inoculated into 100mL Chl-a at 659.68μg / L and 1294.22μg / L, 4259.88μg / L Microcystis aeruginosa liquid was cultured with shaking in an Erlenmeyer flask for 6 days. After 6 days, the algae lysis rates were 77.1%, 50.13%, and 18.60% respectively. The Chl-a concentration in the Microcystis aeruginosa liquid was converted. Decrease 508.61μg / L, 648.79μg / L, 792.33μg / L (see Figure 4 ). It can be seen that the bacteriolytic ability of XXG strain against Microcystis aeruginosa increases with the increase of the number of Microcystis aeruginosa.
Example Embodiment
[0051] Example 3
[0052] In order to investigate the effect of different volume ratios of bacteria and algae on the algae-lysis effect of XXG strain, the XXG bacteria suspension in the logarithmic growth phase was inoculated into an Erlenmeyer flask containing 100 mL of Chl-a concentration of 1294.22μg / L Microcystis aeruginosa In medium shaking culture for 6 days, the volume ratios of bacteria and algae were 5.0%, 5.2%, 5.4%, 5.6%, 5.8%, 6.0%, and the algae lysis rates after 6 days were 36.03%, 41.66%, 42.24%, 50.13%, 44.56%, respectively. , 47.09% (see Figure 5 ).
