Example Embodiment
[0036] Example 1
[0037] Take 2m 2 In the breeding pond, 500 adult abalones (shell length 4~5cm) need to be added about 100g probiotic powder / day as an example.
[0038] 1) After the marine bacteria Phaeobacter sp. AP1220 and Bacillus stratosphericus A3440 are activated by 2216E solid medium, they are respectively inoculated into 100ml 2216E liquid fermentation medium and cultured with shaking at 28°C for 1 to 3 days to make the cell concentration Reach logarithmic growth phase 0.5~1.0×10 9 cfu / ml;
[0039] 2) After mixing the bacterial fermentation broth, centrifuge, discard the supernatant, wash the bacterial pellet with physiological saline 2 to 3 times, and centrifuge to obtain 1 to 2 g of bacterial mud;
[0040] 3) To prepare a dry powder protective agent, 5.0g of sucrose and 2.0g of sodium alginate are required, and the volume is adjusted to 100ml with water, mixed well, sterilized at 115°C for 30min, and cooled to 30~35°C for use;
[0041] 4) Add 2ml of dry powder protective ag...

[0047] Example 2
[0048] Take 2m 2 In the breeding pond, 2000 juvenile abalones (1.5-3cm) need to be added with 50g probiotic powder / day as an example.
[0049] 1) After the marine bacteria Phaeobacter sp. AP1220 and Bacillus stratosphericus A3440 are activated by 2216E solid medium, they are respectively inoculated into 100ml liquid fermentation medium and cultured with shaking at 28°C for 1 to 3 days to make the cell concentration reach Logarithmic growth period 0.5~1.0×10 9 cfu / ml;
[0050] 2) After mixing the bacterial fermentation broth, centrifuge, discard the supernatant, wash the bacterial pellet with physiological saline 2 to 3 times, and centrifuge to obtain 1 to 2 g of bacterial mud;
[0051] 3) To prepare a dry powder protective agent, 5.0g of sucrose and 2.0g of sodium alginate are required, and the volume is adjusted to 100ml with water, mixed well, sterilized at 115°C for 30min, and cooled to 30~35°C for use;
[0052] 4) Add 2ml of dry powder protective agent to the bac...
