Embodiment 1
[0045] Embodiment 1, inhibit and remove the preparation of culture pond macroalgae bacterial agent
[0046]Step 1: Preparation method of bacterial culture medium (pH7.0): 5g peptone, 1g yeast extract powder, 0.01g ferric phosphate, 0.04g NaHCO 3 , 0.02g MgSO 4 ·7H 2 O, 0.02g K 2 HPO 4 , 0.1g NH 4 Cl, dilute to 1000ml with old sea water; in practical application, the pH of the fermentation medium can be 6.5-7.5.
[0047] Step 2: Sterilize the strain liquid culture medium at 120° C. for 15-20 minutes.
[0048] Step 3: Use a 200L fermenter and modify the fermenter as follows: (1) Install a red underwater light at the bottom of the fermenter (the light mainly provides the necessary light source for the growth of capsular rhodobacter as energy); (2) Install an electric thermostat control rod at the lower part of the fermenter; (3) Set two external openings at the bottom of the fermenter, one is used as a ventilation port for supplying the fermenter, and the other is used as a...
Embodiment 2
[0052] Embodiment 2, inhibit and remove the preparation of culture pond macroalgae bacterial agent
[0053] Step 1: Preparation method of bacterial culture medium (pH7.0): 5g peptone, 1g yeast extract powder, 0.01g ferric phosphate, 0.04g NaHCO 3 , 0.02g MgSO 4 ·7H 2 O, 0.02g K 2 HPO 4 , 0.1g NH 4 Cl, dilute to 1000ml with old sea water; in practical application, the pH of the fermentation medium can be 6.5-7.5.
[0054] Step 2: Sterilize the strain liquid culture medium at 120° C. for 15-20 minutes.
[0055] Step 3: Use a 200L fermenter and carry out the following transformations on the fermenter: (1) Install an electric heating constant temperature control rod at the bottom of the fermenter; (2) Set two external openings at the bottom of the fermenter, one as a vent for the fermenter , and the other as an opening for adding culture medium, nutrient salts and strains.
[0056] Add 160L of liquid culture medium to the fermenter, and then inoculate Rhodobacter capsularis...
Embodiment 3
[0059] Embodiment 3, inhibit and remove the preparation of culture pond macroalgae bacterial agent
[0060] Step 1: Preparation method of bacterial culture medium (pH7.0): 5g peptone, 1g yeast extract powder, 0.01g ferric phosphate, 0.04g NaHCO 3 , 0.02g MgSO 4 ·7H 2 O, 0.02g K 2 HPO 4 , 0.1g NH 4 Cl, dilute to 1000ml with old sea water; in practical application, the pH of the fermentation medium can be 6.5-7.5.
[0061] Step 2: Sterilize the strain liquid culture medium at 120° C. for 15-20 minutes.
[0062] Step 3: Use a 200L fermenter and make the following modifications to the fermenter: (1) Install a red underwater light at the bottom of the fermenter (the light mainly provides the necessary light source for the growth of capsular rhodobacter as energy); (2) Install an electric thermostat control rod at the lower part of the fermenter; (3) Set two external openings at the bottom of the fermenter, one is used as a ventilation port for supplying the fermenter, and the...
