Here we show that plant xylem from the sapwood of coniferous trees – a readily available, inexpensive, biodegradable, and disposable material – can remove bacteria from water by simple pressure-driven filtration. Approximately 3 cm 3 of sapwood can filter water at the rate of several liters per day, sufficient to meet the clean drinking water needs of one person. The results demonstrate the potential of plant xylem to address the need for pathogen-free drinking water in developing countries and resource-limited settings.", "link"=>"http://www.mendeley.com/research/water-filtration-using-plant-xylem", "reader_count"=>147, "reader_count_by_academic_status"=>{"Unspecified"=>3, "Professor > Associate Professor"=>7, "Student > Doctoral Student"=>5, "Researcher"=>30, "Student > Ph.
