This article deals with the comparison of two pulsed light devices to highlight the impact of physical characteristics on the decontamination efficiency of micro-organisms, in particular the mould Aspergillus brasiliensis which is the reference germ for UV treatments according to VDMA.
The VDMA  specifies in its practice code, which allows to test the efficiency of the sterilisation devices on packaging, that the inoculums should be prepared without salt. Indeed during the drying of the inoculums the presence of salt forms like a protective layer on it and it has an important impact on the decontamination results.
We could consider them as synonyms. However, for the persons familiarized with microbiology, these words do not mean definitiely the same thing. As a grammar rule, these words follow microbiologic rules.
