Embodiment 1
[0036] Example 1 10L fermenter fermentation (corn flour liquefaction)
[0037] Take 1 glycerol tube strain of Clostridium acetobutylicum (Clostridium acetobutylicum or Clostridium saccharobutylacetonicum), and inoculate it in a test tube containing 25 mL medium (30% potato, 5% sucrose, 1.0% potassium dihydrogen phosphate, natural pH), 100°C, heat shock for 1.5-2min, 38-40°C, and culture in a constant temperature incubator for 24-48 hours to obtain the first-grade seed liquid. Inoculate 25ml of first-grade seed liquid into a 10L fermenter for fermentation. The fermenter has a liquid volume of 6L. The composition of the fermentation medium is 8% corn flour and the pH is natural. Before inoculation, raise the temperature of 8% corn flour liquid to 80-100°C, add high-temperature α-amylase according to 1-30IU enzyme / g starch, liquefy for 1-50min, control the DE value of the liquefied liquid at 1-20%, and then At 121-123°C, high-temperature steam sterilization for 20-30 minutes, ...
Embodiment 2
[0039] Example 2 10L fermenter fermentation (corn starch liquefaction)
[0040] Take 1 glycerol tube strain of Clostridium acetobutylicum (Clostridium acetobutylicum or Clostridium saccharobutylacetonicum), and inoculate it in a test tube containing 25 mL medium (30% potato, 5% sucrose, 1.0% potassium dihydrogen phosphate, natural pH), 100°C, heat shock for 1.5-2min, 38-40°C, culture in a constant temperature incubator for 24-48 hours to obtain the first-grade seed liquid, inoculate 25ml of the first-grade seed liquid into a 10L fermenter for fermentation, the amount of liquid in the fermenter 6L, composition of fermentation medium: 6.5% corn starch, natural pH. Before inoculation, raise the temperature of 6.5% cornstarch solution to 80-100°C, add high-temperature α-amylase according to 1-30IU enzyme / g starch, liquefy for 1-50min, control the DE value of the liquefied solution at 1-20%, and then Add 1.0% yeast extract to the liquefaction solution. According to the nitrogen...
Embodiment 3
[0042] Example 3 10L fermenter fermentation (using potatoes as raw material for liquefaction and fermentation)
[0043] According to the method described in Example 2, obtain 25ml seed liquid, inoculate 25ml primary seed liquid in 10L fermenter and carry out fermentation, fermenter liquid volume 6L, fermentation medium composition: preparation total sugar is 6.5% potato culture Base, pH natural. Before inoculation, heat the potato liquid to 80-100°C, add high-temperature α-amylase at 1-30IU enzyme / g starch, liquefy for 1-50min, control the DE value of the liquefied liquid at 1-20%, and then add it to the liquefied liquid 1.0% yeast extract, according to the nitrogen content of the yeast extract, the carbon-nitrogen ratio is about 40-200, and the mixed material is sterilized by high-temperature steam at 121-123°C for 20-30min, and cooled to 38-40°C , inoculated and fermented. The fermentation temperature is 38-40°C, the fermentation period is 50-65 hours, the solvent outpu...
