Konidien-Suspension, 254 nm, 20 °C, pH 7.9 — Aflatoxin-Bildner (mit A. parasiticus der wichtigste). Literaturwerte streuen stark (~5 mJ/cm2 Nourmoradi 2012 bis ~331 mJ/cm2 Begum 2009); auf rauen Kaffeebohnen-Oberflächen bis ~3429 mJ/cm2 (Byun 2020).
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 35.6 mJ/cm²
Morphology & UV-C resistance
Morphology class Mold spore (conidia)
Konidie mit gelb-grünem Pigment — mässige bis hohe UV-Resistenz; auf rauen Substraten (Kaffeebohnen, Getreide) extrem hohe Dosis nötig.
