Human activities have released large amounts of toxic organic and inorganic chemicals into the environment. Toxic waste streams threaten dwindling drinking water supplies and impact terrestrial, estuarine and marine ecosystems. Cleanup is technically challenging and the costs based on traditional technologies are exceeding the economic capabilities of even the richest countries. Recent advances in our understanding of the microbiology contributing to contaminant transformation and detoxification has led to successful field demonstrations. Hence, harnessing the activity of naturally occurring bacteria, particularly the power of anaerobic reductive processes, is a promising approach to restore contaminated subsurface environments, protect drinking water reservoirs and to safeguard ecosystem health.
人类活动已向环境中释放了大量有毒有机和无机化学物质。有毒废物流威胁着日益减少的饮用水供应，并影响陆地、河口和海洋生态系统。清理工作在技术上具有挑战性，而且基于传统技术的成本甚至超出了最富裕国家的经济承受能力。我们对有助于污染物转化和解毒的微生物学的最新认识进展已促成了成功的实地示范。因此，利用天然存在的细菌的活性，尤其是厌氧还原过程的能力，是恢复受污染的地下环境、保护饮用水源以及维护生态系统健康的一种有前景的方法。
