Embodiment 1
[0036] The method for the production of 3-hydroxypropanal of the probiotic high-yield bacterial strain among the present invention, carries out according to the following steps:
[0037] 1. Preparation medium: peptone 10g, beef extract 10g, glucose 20g, yeast extract 5g, Tween 801ml, dipotassium hydrogen phosphate 2g, triammonium citrate 2g, sodium acetate 5g, magnesium sulfate 0.5g, manganese sulfate 0.2g , L-cysteine 0.5g, sodium thioglycolate 0.05g, VB120.005g, glycerol 3.68g add water to 1L, adjust the pH value to 6.8;
[0038] 2. Insert Lactobacillus reuteri RS01 of the present invention into the culture medium prepared in step 1, and perform anaerobic fermentation at 37°C for 5h;
[0039] 3. Separation: The plate and frame separation is used for the first separation, and the collected bacteria are fast and not easy to cause the death of the bacteria; then the separated bacteria are inserted into a new medium, and the dissolved oxygen is 0 at 37 ° C. , cultivated for 4...
