Many aromatic compounds used for growth substrates by bacteria are broken down during high heat autoclaving.Which is the BEST way to sterilize these aqueous solutions?
A) ethylene oxide gas treatment
B) gamma irradiation
C) 0.2 μm filter sterilization
D) ultraviolet radiation

Question

Quizplus · Accepted Answer

0.2 μm filter sterilization is the best choice because it effectively removes bacteria and other microorganisms without altering the chemical composition of the aromatic compounds in the solution. Ethylene oxide gas treatment and gamma irradiation may cause chemical changes or damage to the compounds, while ultraviolet radiation may not penetrate through the solution to effectively sterilize the entire volume.
