Using bacteria to recover dwindling phosphate resource from sewage

March 30th, 2012 by Society for General Microbiology

Bacteria could be exploited to recapture dwindling phosphate reserves from wastewater according to research presented at the Society for General Microbiology’s Spring Conference in Dublin in late March 2012. Phosphorus – in the form of phosphate – is essential for all living things as a component of DNA and RNA and its role in cellular […]

High nutrient inputs exacerbate acidification of coastal waters

November 24th, 2011 by Nature

High nutrient levels could make coastal waters more susceptible to ocean acidification, suggests a study, ‘Acidification of subsurface coastal waters enhanced by eutrophication‘, published online in Nature Geoscience. Alongside atmospheric inputs of carbon dioxide, human inputs of nutrients to the coastal ocean can lead to an increase in the acidity of these waters.
