A state microbe is a microorganism used as an official state symbol. Several U.S. states have honored microorganisms by nominating them to become official state symbols. The first state to declare an Official State Microbe is Oregon which chose Saccharomyces cerevisiae (brewer's or baker's yeast) as the Official Microbe of the State of Oregon in 2013 for its significance to the craft beer industry in Oregon.[1] One of the first proponents of State Microbes was microbiologist Moselio Schaechter, who, in 2010, commented on Official Microbes for the American Society for Microbiology's blog "Small Things Considered"[2] as well as on National Public Radio's "All Things Considered".[3][4]
