Switch Bioworks is a biotech company based in Can Carlos, CA, building precision'engineered microbes for agriculture. The team of internationally trained experts is developing nitrogen-fixing microbial consortia that naturally live on crop roots as low-cost, environmentally-friendly biofertilizers. Switch sets itself apart from other biological companies by using synthetic biology "switches," that trigger fertilizer production only after microbes have had a chance to establish themselves on plant roots, solving a long-standing tradeoff between microbial stability in soils and high-performance fertilizer production.
