Practice question
Question
A landfill sample was analyzed by dilution and plating techniques for viable bacterial count. When one gram of the landfill sample was diluted 1 x 10-4 (w/v) it yielded 400 CFU. The viable bacterial count (in million, rounded off to the nearest integer) in one gram landfill sample is _______. (NAT)
Explanation
The principle of microbial physiology explains that growth regulation and phage life cycles follow molecular programs. Hence Option NAT fits best because it corresponds to prokaryotic replication strategies, as documented in authoritative sources on microbiology.
