MCB 3020C Lecture Notes - Lecture 20: Lactose Permease, Relative Growth Rate, Exponential Growth
Document Summary
Measures made in this type of culture is equivalent to a single cell. Later if we plot log # versus time converts this to straight line. The mathematics/kinetics of bacterial growth does not represent: the normal pattern of bacterial growth, it reflects one selected portion of a normal growth curve, namely the. Cells divide at regular intervals known as generation time (g) Applies to populations of cells, not a single cell. Lag phase: does not always occur in the growth of a bacterial population and when it does the duration can vary considerably (k = 0) Exponential/log phase: cannot continue indefinitely, limited (k = positive, reaches a max) Stationary phase: no increase in cell number or cell mass (k = 0) Death phase: cells die exponentially (k = negative) Growth rate is the change in cell number or cell mass per unit of time.
