Considering this, what is the life cycle of a bacteria?
The bacteria life cycle consists of the lag phase, the log or exponential phase, the stationary phase and the death phase. Factors that influence bacterial growth bear heavily on this cycle.
Similarly, what is lag phase of bacterial growth? bacterial growth curve In bacteria: Growth of bacterial populations. During this period, called the lag phase, the cells are metabolically active and increase only in cell size. They are also synthesizing the enzymes and factors needed for cell division and population growth under their new environmental conditions.
People also ask, what happens during the death 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. Death phase: a decline in population numbers due to starvation and/or high toxin concentrations.
What are the 6 conditions for bacterial growth?
Terms in this set (6)
- Reservoir. Environment where most microbes grow.
- Food. Water and nourishment.
- Oxygen. Most need oxygen to survive.
- Darkness. Warm and dark environments is needed.
- Temperature. Most grow best at body temperature.
- Moisture. Grow well in moist places.
