What type of media is used to demonstrate oxygen requirements of microbes?
A)blood agar
B)thioglycollate
C)sulfite polymyxin sulfadiazine
D)sodium chloride

Question

Quizplus · Accepted Answer

Thioglycollate broth is a type of media used to demonstrate the oxygen requirements of microbes. It contains a reducing agent (thioglycollate) that consumes oxygen, creating a concentration gradient that allows for the growth of aerobic, facultative anaerobic, and anaerobic organisms in different regions of the tube. Blood agar (A) is a differential medium used to detect hemolytic activity in bacteria. Sulfite polymyxin sulfadiazine (C) is a selective and differential medium used for the isolation and identification of Salmonella spp. from clinical and non-clinical samples. Sodium chloride (D) is a common component of many types of media but is not used specifically to demonstrate oxygen requirements.
