So, in this question, we are asked to list the phases of the bacterial growth.
00:10
So, first, we have the lag phase.
00:18
So, in the lag phase, the bacteria has been introduced to the nutrient medium and in this phase, the bacteria does not reproduce but prepares itself for the process of reproduction and the cells here are, they are active metabolically and they keep increasing in their size and the cells here also, they synthesize the iron in the growth factors, the other molecules that are required for the process of cell division and after the lag phase comes the log phase.
01:19
So, in this phase, the preparation phase, that is the log phase begins and the bacterial cells enter the log phase.
01:33
So, the log phase is also known as the exponential phase.
01:41
So, this phase is marked by the doubling of the bacterial cells and the cell number increases in a logarithmic fashion in this phase so that the cell constitution is being maintained and the log phase, it continues until there is depletion of the nutrients in the setup and the stage also comes to an end, to a stop if the toxic substance starts to accumulate, resulting in a slower growth rate...
