Zell-Suspension in Peptonwasser, UV-C-LED 266 nm, 22 °C (Stamm KCCM 11523) — Brauerei-Untergärhefe; extrem UV-empfindlich. Mit 279 nm UV-LED D90 nur ~0.4 mJ/cm2.
UV-C dose–response (D-values)
A D-value is the UV-C dose (in mJ/cm²) needed for a given log-reduction. D90 = 90 % inactivation = 1-log; D99 = 99 % = 2-log; D99.9 = 99.9 % = 3-log, and so on. Values come from the cited study under its specific test conditions.
Reduction log Dose (mJ/cm²)
D90 90 % 1-log 1 mJ/cm²
Morphology & UV-C resistance
Morphology class Budding yeast
