The propagation and growth of yeast

The propagation and growth of yeast can be divided into six different stages.

 
1. The adjustment period is also the initial stage, which is the activation process of metabolism. The duration of this stage of love varies greatly depending on the type of organism, the cultivation of algebra, and the cultivation of conditions. Once the cell begins to separate, it means the end of this phase.    
             
2. Acceleration period follows the the adjustment period, and cell separation is accelerated. 
 
3.  Logarithm growth 
At this stage, the cell presents logarithmic proliferation, with the maximum value added and constant.
This is when the new generation takes the shortest time (that is, doubling the number of cells).
The time period is 90~120 minutes under the best value-added conditions.
 
4. Deceleration period
Due to various factors, such as the decrease of substrate and the increase of metabolites that inhibit growth, there is a certain time limit in the logarithmic growth stage, and then the deceleration period of gradual reduction of the increment speed is followed.
 
5. Stable period
The number of microorganisms at this stage remains constant.
The number of new cells formed is the same as the number of dead cells.
 
6. Death period
At this stage, the number of cell deaths is more than the number of new cells formed, and the number of cells decreases.
