Pin On Genetics Molecular Biology Learn vocabulary terms and more with flashcards games and other study tools. . When suitable environment is available bacterium is incubated. Stationary Phase- Population growth levels off as the. Log Phase or Exponential Phase 3. What is the lag phase. The resulting curve has four distinct. In a closed system with enough nutrients a bacteria shows a predictable growth pattern that is the bacterial growth curve. Read on to learn about the. Population growth is studied by analyzing the growth curve of amicrobial culture. Therefore the Bacterial growth curve consists of 4 different phases such as the lag phase the exponential or logarithmic phase stationary phase and death or decline phase.
