The typical key bacteria found in the nose are:
The test procedure for Standard 44.10 nasal microbiome
The textile product undergoes four test phases as part of the "Microbiome-friendly" certification.
All textiles are washed in our laboratory according to a standardized procedure.
Hygiene products are sterilized through UV light exposure.
The balance between the commensal bacteria S. epidermidis and the harmful bacteria S. aureus should not be disturbed by the nasal textile product. A co-culture consisting of both germs is mixed with the product for a certain period of time and then the ratio of the two microbes is compared to an untreated control group. Under the influence of the textile product, this must not shift in favor of S. aureus.
In this step, we cultivate the key microbes common to the nose. For the 44.10 standard, these are Moraxella catarrhalis, Staphylococcus epidermidis, Cutibacterium acnes, Corynebacterium striatum.
A co-culture of all germs is mixed with the product to be tested and the change in diversity is compared with the untreated control group. The diversity of the nasal microbiome must be preserved with regard to the most important key microbes.
A Microbiome-friendly textile product for the nose should not only preserve diversity, but it should also not prove detrimental to the growth of microbes. The test simulates skin contact using a model. Each key microbe is brought into direct contact with the product. The microbial growth is compared with the untreated control group, and the growth must not be significantly inhibited.
"Textiles which aim to have a positive contribution to the skin microbiome are best to be engineered to preserve the steady-state of it."
