During which growth phase will grampositive bacteria be most

During which growth phase will gram-positive bacteria be most susceptible to penicillin? a) Lag phase b) Log Phase c) Death phase d) Stationary phase e) The culture is equally susceptible during all phases

Solution

ans-B -Log phase

Penicillin and other antibiotics are most effective against rapidly in log phase or exponential phase because cell divide very rapidly in an exponential function, they are most metabolically active and bacteria are adjusting new environment
