Methane is a major greenhouse gas and a clean alternative fuel. Bacteria that consume methane as a food source are therefore of great interest to environmental and industrial scientists. These bacteria may be manipulated to reduce atmospheric methane emissions from natural or man-made environments, and thereby reduce global warming. We plan to study the ecology and genetics of methanotrophic (methane-eating) bacteria in some important Canadian ecosystems such as northern wetlands, industrial tailings, and forest soils. We will search for unusual species of these bacteria by recovering their unique DNA sequences directly from the environment.

甲烷是一种主要的温室气体，也是一种清洁的替代燃料。因此，以甲烷为食物来源的细菌引起了环境和工业科学家的极大兴趣。可以操纵这些细菌来减少自然或人造环境中的大气甲烷排放，从而减少全球变暖。我们计划研究加拿大一些重要生态系统（例如北部湿地、工业尾矿和森林土壤）中甲烷氧化（吃甲烷）细菌的生态学和遗传学。我们将通过直接从环境中恢复这些细菌独特的 DNA 序列来寻找这些细菌的不寻常物种。
