The Washing Machine Microbiome Project
Keeping people healthy through household hygiene is becoming increasingly important and cleaning of textiles plays a central role. Following current trends in sustainability and energy conservation, low-temperature washing is also becoming increasingly popular in German private households. However, these trends must be viewed critically, as up to 30% of all microorganisms isolated from washing machines are potentially pathogenic. During this project, the microbiome of washing machines and worn textiles, and changes due to washing processes will be investigated. The aim is to determine the composition of the microbiome (bacteria, fungi, viruses) of washing machines at different locations. Of particular interest is the presence of antibiotic-resistant bacteria such as MRSA (methicillin-resistant Staphylococcus aureus) and/or ESBL (extended-spectrum beta-lactamase)-forming pathogens. Extensive metabolome analyses of microbial metabolites from all relevant sample materials and from the in-vitro models to be established will also be performed, mainly by GC- and LC-MS-based methods. More than 100 metabolites are quantified from individual samples to determine the relevant metabolic activities of the microorganisms.
