This minireview provides a synopsis of past and present research on the biology and ecology of members of the bacterial genus Collimonas. From the distribution, abundance and functional behaviours of these so-called collimonads emerges a general picture of bacterial adaptation to low-nutrient soil environments. Among these adaptations is the ability to extract nutrients from living fungi (mycophagy) and from rocks and minerals (weathering). This unique combination of properties will be discussed in the context of other interactions that collimonads have with their biotic and abiotic surroundings, such as the ability to inhibit fungal growth (fungistasis), protect plant roots from fungal disease (biocontrol), and degrade natural polymers and synthetic pollutants (biodegradation). Future research on Collimonas is expected to take advantage of the genomic tools and resources that are becoming available to uncover and describe the genes and gene functions that distinguish this group of bacteria and are the basis for its phenotypes. Potential applications of collimonads include the control of unwanted fungi, for example in agriculture, their use as biological indicators of soil quality and fertility, and as a source of bioactive compounds.
这篇综述简要介绍了过去和现在有关细菌属 Collimonas 成员的生物学和生态学的研究。从这些所谓的 collimonads 的分布、丰度和功能行为中，可以得出细菌适应低营养土壤环境的一般情况。这些适应包括从真菌（食真菌）和岩石和矿物质（风化）中提取营养物质的能力。将在 collimonads 与其生物和非生物环境相互作用的背景下讨论这种独特的特性组合，例如抑制真菌生长（抑菌）、保护植物根系免受真菌病害（生物防治）以及降解天然聚合物和合成污染物（生物降解）的能力。对 Collimonas 的未来研究有望利用现有的基因组工具和资源来揭示和描述区分这组细菌的基因和基因功能，以及它们表型的基础。collimonads 的潜在应用包括控制不需要的真菌，例如在农业中的应用，将它们用作土壤质量和肥力的生物指标，以及用作生物活性化合物的来源。
