Scientists have long been captivated by a group of microscopic organisms in Yellowstone National Park. The microbes thrive at extreme temperatures and can efficiently multiply with limited resources. The feat has inspired a company called Sustainable Bioproducts, which is replicating the process in a laboratory and eventually, it hopes, at a large scale.
On Monday, the Chicago-based startup said it raised $33 million to accelerate the research. Venture firm 1955 Capital led the round, which also included Breakthrough Energy Ventures, a climate-focused technology fund backed by a roster of billionaires including Amazon.com Inc.’s Jeff Bezos and Microsoft Corp.’s Bill Gates. Michael Bloomberg, the founder and majority owner of Bloomberg LP, is also an investor in the fund.
