Bacterial Reproduction, Growth and Preservation-Page 1 B. Bacterial Reproduction, Growth and Preservation 1. Growth Increase in the population of cells is called a Culture. Growth of culture goes through 4 phases with time, when plotted on a graph. They are synthesizing DNA, ribosomes and enzymes to breakdown nutrients, and to be used for growth. Cells are most susceptible to inhibitors.
Stationary phase Dying and dividing organisms are at an equilibrium.
Cells are smaller and have fewer ribosomes. In some cases cells do not die but they are not multiplying. The population is dying in a geometric fashion so there are more deaths than new cells. Deaths are due to the factors in stationary phase in addition to lytic enzymes that are released when bacteria lyse.
