Microorganisms that grows best with high levels of carbon dioxide in addition to low levels of oxygen. (Microbiology with Disease by Taxonomy, 2nd ed., Robert Bauman)
capnophiles
Capnophiles, which enjoy CO2
Capnophiles grow best under conditions of high carbon dioxide levels. They thrive in environments with elevated CO2 concentrations, which can be beneficial for their growth and metabolic activities. Typically, capnophiles are able to utilize CO2 as a carbon source for their energy needs, making them well-adapted to environments with increased levels of this gas.
Microbes that prefer an atmosphere of carbon dioxide are known as carbon dioxide-loving or CO2-loving microbes. Some examples include certain types of bacteria and archaea that thrive in environments with high levels of carbon dioxide.
