In this study, researchers explored the bacterial communities present in different types of microwaves, focusing on domestic, shared, and laboratory microwaves. The research aimed to explore how usage patterns, environmental conditions, and human interaction influence the microbiomes of these commonly used appliances. Utilizing next-generation sequencing and culturing techniques, the results revealed distinct microbial profiles across the three types of microwaves, with domestic microwaves showing a prevalence of bacteria associated with human skin and food, while laboratory microwaves were dominated by extremophiles adapted to high radiation, high temperatures, and desiccation. The study highlight the impact of human interaction, nutrient availability, and environmental conditions on microwave microbiomes, pointing to potential health risks from pathogenic bacteria in domestic microwaves and the importance of regular cleaning practices.
