Kula Bio

Kula Bio is a Massachusetts climate-tech company turning naturally occurring nitrogen-fixing microbes into living fertilizer factories that run inside the soil. Born from Harvard chemist Dan Nocera's 'bionic leaf' research, the company supercharges Xanthobacter autotrophicus with a renewable-energy carbon source so the bacteria deliver plant-available nitrogen at the root zone, on demand. Field trials show its flagship Kula-N can replace as much as 80% of a farm's synthetic nitrogen use without the runoff or the fossil-fuel footprint of conventional fertilizer.
