Embodiment 1
[0018] Embodiment 1: a kind of method for fermenting soybean molasses to produce citric acid comprises the following steps:
[0019] (1) Preparation of medium
[0020] Preparation of strain activation medium: add 50 g of peeled potatoes and 200 mL of distilled water to boil for 30 min, filter, take the filtrate, add 5 g of glucose, 4.5 g of agar, distill water to 250 mL, sterilize at 121°C for 20 min, then pour Put it into a test tube and lay a slant surface to prepare a slant medium for future use.
[0021] Preparation of seed medium: Add 50 mL of 60 g / L soybean molasses solution to a 250 ml Erlenmeyer flask, add 2.5 g of glucose, distill water to 100 mL, sterilize at 121°C for 20 min, and cool for later use.
[0022] Preparation of fermentation medium: adjust the initial sugar content of soybean molasses to 26% (mass concentration), add newly prepared 15% lime milk to adjust the pH to 9.0, heat to boil, filter, and adjust the filtrate to pH 6.0 with sulfuric acid, then add ...
