Microwaves have become an essential part of the modern kitchen, but their potential as a reservoir for bacterial colonization and the microbial composition within them remain largely unexplored. In this study, we investigated the bacterial communities in microwave ovens and compared the microbial composition of domestic microwaves, microwaves used in shared large spaces, and laboratory microwaves, using next-generation sequencing and culturing techniques. The microwave oven bacterial population was dominated by , , , and , similar to the bacterial composition of human skin. Comparison with other environments revealed that the bacterial composition of domestic microwaves was similar to that of kitchen surfaces, whereas laboratory microwaves had a higher abundance of taxa known for their ability to withstand microwave radiation, high temperatures and desiccation. These results suggest that different selective pressures, such as human contact, nutrient availability and radiation levels, may explain the differences observed between domestic and laboratory microwaves. Overall, this study provides valuable insights into microwave ovens bacterial communities and their potential biotechnological applications.
微波已成为现代厨房的重要组成部分，但其作为细菌定植场所的潜力以及其中的微生物组成在很大程度上仍未得到探索。在本研究中，我们调查了微波炉中的细菌群落，并使用下一代测序和培养技术比较了家用微波炉、共享大空间中使用的微波炉和实验室微波炉的微生物组成。微波炉细菌种群以 、 、 和 为主，类似于人类皮肤的细菌组成。与其他环境的比较表明，家用微波炉的细菌组成与厨房表面相似，而实验室微波炉中具有耐受微波辐射、高温和干燥能力的分类群丰度更高。这些结果表明，不同的选择压力，如人类接触、营养可用性和辐射水平，可能解释了家用微波炉和实验室微波炉之间观察到的差异。总体而言，本研究为微波炉细菌群落及其潜在的生物技术应用提供了有价值的见解。
