destroy microorganisms through inihibiting their development or action
antimicrobial agents
22

Penicillin notatum or Penicillin chrysogenum
23
means bacteria is capable of producing secondary metabolites which can inhibit growth of other bacteria
zone of inhibition/clear zone
24
which phase of bacterial growth curve shows symptoms
log phase
25
which phase of bacterial growth curve represents the bacteria still adjusting, just inoculated, synthesizing enzymes
lag phase
26
During this phase, the microorganisms are in a rapidly growing and dividing state.
log phase
27
During this phase, cells undergoing division is equal to the number of cell death, and finally bacterium stops its division completely
stationary phase
28
During this phase, the individual is feeling better
stationary phase
29
during this phase, the number of dead cells exceeds the number of live cells.
decline phase
