A microbiology lab technician is preparing to culture a bacterial specimen that is suspected to be an obligate anaerobe. What specific condition is essential for the successful growth of this type of microorganism?

Accepted Answer

B. Absence of oxygen — Obligate anaerobes are microorganisms that cannot grow in the presence of oxygen and may even be harmed by it. Therefore, an essential condition for their successful culture is the complete absence of oxygen. High oxygen concentration would inhibit their growth. While carbon dioxide can be important for some bacteria, it's not the defining factor for obligate anaerobes. Room temperature incubation is a general condition and not specific to the oxygen requirement of anaerobes.
