Water Filtration Using Plant Xylem
Effective point-of-use devices for providing safe drinking water are urgently needed to reduce the global burden of waterborne disease. 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 ...
متن کاملMembraneless water filtration using CO2
Water purification technologies such as microfiltration/ultrafiltration and reverse osmosis utilize porous membranes to remove suspended particles and solutes. These membranes, however, cause many drawbacks such as a high pumping cost and a need for periodic replacement due to fouling. Here we show an alternative membraneless method for separating suspended particles by exposing the colloidal s...
متن کاملPhloem-and xylem-restricted plant pathogenic bacteria
This review concerns plant pathogenic bacteria, which are strictly restricted either to the sieve tubes in the phloem or to the vessels in the xylem. These bacteria are endogenous as opposed to exogenous bacteria such as species of Erwinia , Pseudomonas , Ralstonia or Xanthomonas , which colonize the apoplast (intercellular spaces) of plant tissues, even though some of the exogenous bacteria, s...
متن کاملA mathematical model of water and nutrient transport in xylem vessels of a wheat plant.
At a time of increasing global demand for food, dwindling land and resources, and escalating pressures from climate change, the farming industry is undergoing financial strain, with a need to improve efficiency and crop yields. In order to improve efficiencies in farming, and in fertiliser usage in particular, understanding must be gained of the fertiliser-to-crop-yield pathway. We model one as...
متن کاملConstructing gene-enriched plant genomic libraries using methylation filtration technology.
Full genome sequencing in higher plants is a very difficult task, because their genomes are often very large and repetitive. For this reason, gene targeted partial genomic sequencing becomes a realistic option. The method reported here is a simple approach to generate gene-enriched plant genomic libraries called methylation filtration. This technique takes advantage of the fact that repetitive ...
