Following the lag phase is the log phase, in which population grows in a logarithmic fashion. As the population grows, the bacteria consume available nutrients and produce waste products. In batch culture, there is an initial phase of no growth (lag phase), which is followed by rapid growth (exponential growth), then there is leveling off (stationary phase) and finally a decline in the viable cell count (death or decline phase). Between each of these phases, there is a transition period (curve portion). The log phase is generally quite rapid and puts the bacterial cells in a vulnerable position.

Log phase: the number of bacterial cel Bacterial growth always follows a predictable pattern with four phases: Lag phase: very little to no bacterial growth.

The four phases are lag log stationary and death The Lag Phase The beginning of from MICRO 20 at California State University, Fresno Ale fermentation of brewers wort follows three phases: the lag phase for 3-15 hours, an exponential growth phase for 1-4 days, and a stationary phase of yeast growth for 3-10 days. Each of these phases will be described in terms of yeast behavior.

Lag Phase When a new propagator or fermenter is inoculated with yeast, the yeast enters a period of time where they are metabolically active, but not dividing, called lag phase.

What happens during the log phase of bacterial growth? Log phase: the number of bacterial cells doubles at a constant, exponential rate. Stationary phase: population growth levels off as the rate of cell death equals the rate of cell division.
