In this study, Kombucha, a fermented drink by adding beneficial bacteria to green tea or black tea with sugar, was classified using column chromatography, and the presence or absence of quercetin glycoside, a type of flavonoids, was confirmed through TLC. In addition, the anti-pollution effect of protecting and improving the skin from pollution was confirmed using the fraction. Keratinocytes were treated with K-QG to confirm the cell viability, showing a survival rate of 90% or more up to a concentration of 100 ㎍/mL, and the cell viability by benzo[e]pyrene and fine dust stimulation to see the anti-pollution effect was measured. At 100 ㎍/mL, the improvement rates were about 68.79% and 50.68%, respectively. In addition, as a result of confirming the expression of AhR activated by benzo[a]pyrene through Western blot, it showed an inhibition rate of about 31.08% at 100 ㎍/mL compared to the control group. Through the results of this study, K-QG is thought to be valuable as an anti-pollution functional material, protecting and improving skin irritated from benzopyrene and fine dust.

Dextranase는 dextran의 $\alpha-1,6-glycoside$ 결합을 끊는 효소로써 치석을 형성하는데 요인이 되는 dextran을 분해 제거하는 역할을 한다. 본 실험에서는 이러한 dextranase 생산 곰팡이류 중에서 Penicillium 속에 속하는 균주를 선정하여 이 효소 생산의 최적조건을 실험 검토하였다.
