Capnophiles are microorganisms that thrive in the presence of high concentrations of carbon dioxide (CO2). They require elevated CO2 levels for optimal growth and survival.
5 Must Know Facts For Your Next Test
Capnophiles typically require CO2 concentrations between 5% to 10% for optimal growth.
These microorganisms can be found in environments where CO2 is naturally higher, such as the gastrointestinal tract or respiratory system.
Capnophiles include various pathogenic bacteria, such as Neisseria gonorrhoeae and Haemophilus influenzae.
Special incubators or candle jars are often used in laboratories to cultivate capnophiles by creating a high-CO2 environment.
The term 'capnophile' is derived from Greek words 'kapnos' meaning smoke and 'philos' meaning loving.
