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
