Abstract: Novel uracil-DNA glycosylase (UDG) derived from Photobacterium leiognathi and uses thereof are disclosed. The novel UDG is an enzyme isolated from Photobacterium leiognathi, which is a psychrophilic bacterium, and is characterized by having an activity of degrading uracil bases from uracil-containing DNA substrate and being easily denatured at low temperatures. Accordingly, the UDG can be effectively used to eliminate carryover contamination occurring during the nucleic acid amplification reaction, resulting in increased accuracy (elimination of false positives), purity and amplification efficiency in nucleic acid amplification reactions.

Abstract: Disclosed in the present disclosure is a composition for improving skin damage caused by fine dust, which contains an Aureobasidium pullulans strain; a lysate thereof; a culture thereof; or an extract of the strain, the lysate or the culture as an active ingredient, and the composition has an effect of promoting the expression of keratinocyte differentiation markers and granular layer tight junction markers, thereby enhancing the skin barrier function and having skin-moisturizing, anti-aging and wrinkle-suppressing effects, and, thus, has an excellent effect in terms of improving skin damage caused by fine dust.
