Konidien des Norm-Test-Stamms DSM 1988 (= A. niger ATCC 16404) auf Polystyrol-Oberfläche, 254 nm; in Wasser-Suspension D90 ca. 225 mJ/cm2. Standard-Resistenz-Referenzstamm (u.a. EN 13697 / EN 14476). Einer der UV-resistentesten verbreiteten Schimmelpilze.

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 413 mJ/cm²

Morphology & UV-C resistance

Morphology class Mold spore (conidia)

Stark melanisierte (schwarze) Konidien — Melanin ist ein hochwirksamer UV-C-Absorber und Radikalfänger; A. niger/brasiliensis zählt zu den UV-resistentesten Schimmelpilzen (~10–50× hyaline Arten).
