The new solution uses bacteria as novel biofilters to reduce nitrate levels in water sources.

The scientists developed novel polymer carrier beads that are loaded with denitrifying bacteria to create bio-filters for the removal of nitrates from water.

The permeable polymer beads can contain either denitrifying bacteria alone or a combination of fermentative and denitrifying bacteria plus a carbon source, to reduce nitrate to nitrogen gas, which evaporates into the atmosphere.

The novel nitrate bio-filter can reduce high nitrate levels in both fresh-water and sea-water, and is easily applicable to water-purification systems for aquariums and nitrate-contaminated bodies of water.

Yissum CEO Yaacov Michlin said this novel technology, for decontaminating water from nitrates and boron, is a cost-effective and efficient technique for decontaminating water from various substances without producing other contaminants.
