The lag phase is the time which is used by the bacteria to get adapted to the newly provided nutrients and physical environment hence, it can called as adaptation period. I. Microbial Growth. A. Phases of Growth - A microbial lab culture typically passes through 4 distinct, sequential phases of growth that form the standard bacterial growth curve: (Not all growth phases occur in all cultures). See graph; be able to draw & label.

Lag phase of microbial growth

However as exponential growth phase begins it is possible to measure dX/dt and dS/dt values which are very useful for defining important microbial kinetic parameters.

Microbial growth respiration parameters, such as lag phase (T lag), actively growing microbial biomass (MB) according to Panikov (1995) and substrate-induced respiration derived microbial biomass content after Anderson and Domsch (1986) including the conversion factor used by Kaiser et al. (1992). 10 Nov 2019 The microbial growth curve consists of 4 phases. Lag phase of the growth curve, Log phase of the bacterial growth curve which is also known 7 Feb 2007 The lag phase is generally thought to be a period during which the cells adjust to a new environment before the onset of exponential growth.

What is happening during the lag phase? This definition from the internet does not explain lag phase at all well. "This lag phase is the period when the bacteria

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). During the lag phase of microbial growth, the cells are metabolically inactive.
