Embodiment 1
[0010] Cultivation of Azotobacter ohroococcum
[0011] a. Primary slant cultivation
[0012] The main ingredients of the culture medium are as follows: 1% sucrose, 0.05% dipotassium hydrogen phosphate, 0.1% calcium carbonate, 0.02% magnesium sulfate, 0.02% sodium chloride and 2% agar. PH7-7.2.
[0013] Put the culture medium into a test tube according to the conventional method, sterilize, inoculate, and incubate at 28±1°C for 24 hours and save it for later use.
[0014] b. Secondary liquid culture
[0015] Remove the agar in the main ingredient formula of the primary medium, and use it as the main ingredient of the secondary medium, pH7-7.2.
[0016] Prepare the culture medium and put it into the Erlenmeyer flask. After sterilizing and cooling, inoculate the slant strains in the liquid culture medium; shake and culture at 28±1°C for 24 hours, when the number of cells reaches 500 million / g, Terminate the culture and reserve.
[0017] c. Tertiary solid culture
[0018] Th...
Embodiment 2
[0021] Cultivation of nitrogen-fixing bacterium Trichoderma koningii
[0022] a. Primary training
[0023] The formula is conventional potato plus agar medium.
[0024] Put the prepared culture medium in a test tube, inoculate it after routine sterilization, and cultivate it at 26±1°C for 3-4 days; after green spores grow, stop the cultivation and save it for later use.
[0025] b. Secondary training
[0026] The medium formula is: bran 50%, cornmeal 40%, straw powder 10%.
[0027] After moistening, sterilizing and cooling the dry material, inoculate the first-grade bacteria and culture it in a glass petri dish. Cultivate at 26±1°C for about 5 days; stop the cultivation after green spores grow. Dry at low temperature (below 60°C) and save for future use.
[0028] c. Tertiary training
[0029] The medium formula is the same as the secondary medium formula.
[0030] After moistening, sterilizing, and cooling the dry material, inoculate the secondary strain, and use the th...
Embodiment 3
[0032] Cultivation of Bacillus megatherium phosphaticum
[0033] a. Primary slant cultivation:
[0034] The medium formula is conventional potato plus agar medium. Sterilize according to conventional methods, inoculate, incubate at 28±1°C for 48 hours, and store for future use.
[0035] b. Secondary liquid culture:
[0036] Remove the agar from the primary medium formulation and use it as a secondary medium.
[0037] Put the culture medium into the Erlenmeyer flask, inoculate the slant strain after autoclaving and cooling, and culture on a shaking table at 28±1°C for 36 hours. When the number of cells reaches 500 million / g, stop the culture and set aside.
[0038] c. Tertiary training
[0039] The medium formula is: bran 30%, sorghum 20%, cornmeal 40%, fly ash 10%.
[0040] Weigh the dry material, moisten it, sterilize it, cool it down, connect it with secondary strains, and culture it on a shallow plate for 48 hours at 28±1°C, and stop the culture when the number of cell...
