3Bar Biologics has partnered with start-up Pivot Bio to develop PROVEN, a low-cost nitrogen-producing microbial product which, if used on 35% of US farms, could eliminate 20,000 mt of N20 emissions annually. CEO Bruce Caldwell, formerly of Procter & Gamble and Scott’s Miracle-Gro, said PROVEN, which fixes nitrogen from the air and secretes it into a crop’s root zone, allows farmers to grow their own microbes on site and store them for up to three weeks. The company is also working on an anaerobic digester that uses bacteria as its primary carbon source.
