TABLE 4.
Lethal dose (LD90) values for Aspergillus niger spores in comparison to different organisms in response to UV-C radiation (254 nm) and X-ray radiation. Values for cells/spores in suspension (wet), irradiated in air.
| Strain | UV-C (J/m2) | References | X-rays (Gy) | References |
| Aspergillus niger (spores) | 1038 | This study | 366 | This study |
| Bacillus subtilis (spores) | 100 | Newcombe et al., 2005 | 857 | Moeller et al., 2014 |
| Deinococcus radiodurans (cells) | 656 | Bauermeister et al., 2009 | ca. 8000 | Moseley and Laser, 1965; Driedger et al., 1970 |
Data reported as LD90 values – dose of radiation treatment leading to a 90% inactivation of the initial CFU (same as D10 values).
