Question

An anaerobic culture should be kept at room temperature and processed within how many hours of collection?

(A) 8 hours
(B) 12 hours
(C) 24 hours
(D) 48 hours

Answer 1

Anaerobic cultures should be kept at room temperature and processed within 24 hours of collection to ensure viability for experimentation.

Step-by-step explanation:

An anaerobic culture should be kept at room temperature and processed within 24 hours of collection. Cultures that grow best at body temperature, such as those incubated at 37°C, if not able to be attended to within 24 to 36 hours, should either be incubated at room temperature, or arrangements should be made to transfer these cultures to a refrigerator. This is to ensure that the culture remains viable for students to complete their experiments. Bacteria that thrive at room temperature should consistently be incubated in those conditions, although growth may take slightly longer. Furthermore, it is crucial to properly disinfect when working with bacteria and to store cultures at optimal temperatures for longevity.
