Embodiment 1
[0030] The antioxidation of embodiment 1 yeast extracellular active substance is measured
[0031] (1) Take the wine and medicine sample to be tested, add sterile water, dilute 10 times in a gradient, oscillate, take the supernatant and spread it on a solid medium, cultivate it for 12-48 hours, and obtain a single colony as the strain to be screened;
[0032] (2) Under sterile conditions, take the bacterial strain to be screened, inoculate it in a multi-hole cell culture plate containing a liquid medium, and activate it for 3 generations before use;
[0033] (3) After centrifuging the activated bacterial solution at 4000r / min for 2min, take the supernatant for later use;
[0034] (4) Carry out the pre-test, take 2 mL of DPPH solution, add a small amount of sample solution to it, when adding the sample, gradually add less and then more, mix while adding, and observe the fading of the solution, when the color of the solution basically fades, record The sample volume of the next...
Embodiment 2
[0041] Example 2 Determination of the tyrosinase inhibitory activity of yeast extracellular active substances
[0042] (1) Take 30 strains to be tested, centrifuge the activated bacterial solution at 4000r / min for 2min, and take the supernatant for use.
[0043] (2) Configure the required solution according to the table below:
[0044] Table 2. Determination of tyrosinase inhibition rate experimental sample addition table
[0045] Unit (mL) C1 C2 T1 T2 PBS buffer 1.5 2.0 1.0 1.5 sample 0 0 0.5 0.5 Tyrosinase 0.5 0 0.5 0 total capacity 2.0 2.0 2.0 2.0
[0046] Add C1, C2, T1, and T2 according to the above table and bathe in a water bath at 37°C for 10 minutes, add 1 mL of dopa solution and bathe in a water bath at 37°C for 4 minutes, and immediately put it into a spectrophotometer at 475nm to measure the absorbance at the 5th minute , Calculate the inhibition rate of the sample to tyrosinase activity T (%)=1-(T1-T2) / (C1-C2...
Embodiment 3
[0050] Antioxidant activity, tyrosinase inhibition rate determination of the active substance in the yeast cell of embodiment 3
[0051] (1) Take the strains 1-13 to be tested, centrifuge the activated bacterial liquid at 4000r / min for 2min, and put the centrifuged supernatant (that is, the mixture of MEB medium and extracellular secretion) in a sterile operating table completely empty;
[0052] (2) Add 0.9ml of sterile water, use a micro-vortex mixer to mix it completely, cover the EP tube, and centrifuge again at low temperature and low speed for a short period of time. The purpose of this centrifugation is to clean up the remaining EP tube The mixed solution of MEB medium and extracellular secretion, repeat this experimental step 2-3 times, until the medium in the EP tube is completely washed;
[0053] (3) Find a small glass beaker, add an appropriate amount of ice-water mixture and a small foam orifice to it, open the EP tube and insert it into the small foam orifice, aft...
