Microbial volatile organic compounds (MVOCs) are diverse molecules produced by microorganisms, ranging from mere waste byproducts to important signalling molecules. While the interest in MVOCs has been increasing steadily, there is a significant gap in our knowledge of MVOCs in extreme environments with e.g. extreme temperatures or acidity. Microorganisms in these conditions are subjected to additional stress compared to their counterparts in moderate environments and in many cases have evolved unique adaptations, including the production of specialized MVOCs. This review highlights the diversity of MVOCs identified in extreme environments or produced by isolated extremophiles. Furthermore, we explore potential applications already investigated and discuss broader implications for biotechnology, environmental biology, and astrobiology.
微生物挥发性有机化合物（MVOCs）是微生物产生的多种分子，从单纯的废物副产物到重要的信号分子不等。虽然对MVOCs的兴趣一直在稳步增长，但我们对极端环境（如极端温度或酸度）中的MVOCs的了解存在重大差距。与中等环境中的微生物相比，这些条件下的微生物会受到额外的压力，并且在许多情况下已经进化出独特的适应性，包括产生特殊的MVOCs。本综述强调了在极端环境中鉴定出的或由分离出的极端嗜热菌产生的MVOCs的多样性。此外，我们探讨了已经研究的潜在应用，并讨论了对生物技术、环境生物学和天体生物学的更广泛影响。
