Embodiment 1
[0032] 1. Collect feces of healthy young adults without family history of hyperglycemia, and isolate lactic acid bacteria strains
[0033] ①Bacteria source: feces of healthy young adults without family history of hyperglycemia
[0034] ② Plate medium: peptone 10g beef powder 5g yeast powder 4g K 2 HPO 4 ·7H 2 O 2g triammonium citrate 2g sodium acetate 3H 2 O 5g glucose 20g Tween 80 1mL MgSO 4 ·7H 2 O 0.2g
[0035] MnSO 4 4H 2 O 0.05g agar 15g distilled water 1000mL
[0036] ③Isolation of strains
[0037] In Bama County, Guangxi Province, the feces of young and middle-aged adults with no family history of blood sugar were sampled, and the samples were sampled with a fecal sampler. During the sampling process, gloves were worn for disinfection to avoid contact with the samples to prevent contamination. Store in a refrigerator immediately after taking it out, and record it with a number.
[0038] The sample liquid was diluted tenfold, and 100 μL of each gradient was ev...
Embodiment 2
[0048] Survival of strains through simulated gastrointestinal digestive fluid
[0049] Preparation of simulated gastric juice: take 16.4mL of 9.5% hydrochloric acid, dilute with distilled water to make the pH value reach 2.0, add 1.0g of pepsin per 100mL, mix well, filter through a 0.22μm sterile filter membrane, and prepare and use immediately. Take 1g of 10 billion / g bacterial powder of JYLR-005 strain, transfer it to a preheated test tube filled with 9mL simulated gastric juice, and treat it at 37°C and 80r / min for 1h, 2h, 3h. The sample solution was serially diluted, counted by pouring method, and each treatment was repeated three times.
[0050] Preparation of simulated intestinal juice: take KH 2 PO 4 6.8g, add 500mL distilled water to dissolve, adjust pH to 6.8 with 4g / L NaOH solution, distill water to 1L, add bile salt 0.3%, add 1g trypsin according to 100mL, mix well, filter with 0.22μm sterile filter membrane, now Ready to use. Take 1g of 10 billion / g bacterial ...
Embodiment 3
[0057] Control Experiment of Adhesion Rate of Different Strains to Caco-2
[0058] Number of sticks at 40 fields of view
[0059] Reagent
[0060] MRS medium: peptone 10.0g, beef powder 5.0g, yeast powder 4.0g, glucose 20.0g, Tween 80 1.0mL, K 2 HPO 4 ·7H 2 O 2.0g, sodium acetate·3H 2 O 5.0g, triammonium citrate 2.0g, MgSO 4 ·7H 2 O 0.2g, MnSO 4 4H 2 O0.05g
[0061] DMEM medium (purchased from GIBCO company)
[0062] PBS 1L formulation pH7.4: Potassium dihydrogen phosphate (KH 2 PO 4 ): 0.27g, disodium hydrogen phosphate (Na 2 HPO 4 ): 1.42g, sodium chloride (NaCl): 8g, potassium chloride (KCl) 0.2g, add about 800mL of deionized water and stir to dissolve, then add concentrated hydrochloric acid to adjust the pH to 7.4, and finally dilute to 1L
[0063] sticky operation
[0064] Caco-2 cells were placed in DMEM medium containing 10% heat-inactivated newborn calf serum and double antibodies (penicillin concentration 100 U / mL, streptomycin 1.0 μg / mL), at 37°C, 5% ...
