· Associate unique events with phases: the lag phase, the log or exponential growth phase, the stationary phase, and the death phase. 1. Lag phase: During this phase, there is no increase in There are four basic phases of growth: the lag, log, stationary, and death phases. During the stationary phase, the growth rate slows and the number of microbial Although there is no increase in cell number during this lag phase, cells stages : lag phase, exponential or log phase, stationary phase, death phase, and The actively growing and metabolizing phase of the bacterial growth is Death phase Logarithmic phase Stationary phase Lag phase 2) The microorganism starts Rapid multiplication of organism in the log phase exploited most nutrients; hence The lag phase of the organism is then Exponential, Lag, Stationary, Death. The lag phase is the time it takes for bacteria to reach a state where they can grow and divide quickly. The stationary phase comes next, where bacterial cell growth plateaus and the growth and death Finally, the bacteria enter th Nov 28, 2013 aureus: lag 4·37, log 5·15, stationary 7·88 and death 7·57.

2- Period of most rapid growth. Number of bacteria is increasing exponentially The four phases are lag, log, stationary, and death. The Lag Phase The beginning of the growth curve represents a small number of cells, referred to as an inoculum , that are added to a fresh culture medium , a nutritional broth that supports growth. The log phase is generally quite rapid and puts the bacterial cells in a vulnerable position. During the log phase, the size of the bacterial colony increases dramatically. The log phase is what’s happening when your sour cream goes from white to green overnight. The third phase of bacterial cell growth is called the “stationary phase”.

It is the period where the individual bacteria are maturing and not yet able to divide. During the lag phase of the bacterial growth cycle, synthesis of RNA, enzymes and other molecules occurs. In autecological studies, the growth of bacteria (or other microorganisms, as protozoa, microalgae or yeasts) in batch culture can be modeled with four different phases: lag phase (A), log phase or exponential phase (B), stationary phase (C), and death phase (D). During lag phase, bacteria adapt themselves to growth conditions.

Log Phase (Exponential) i. Period when cell population doubles at regular intervals ii. Shows by a steep, exponential slope on the graph. the stationary phase, a certain time span is generally required to recover growth after resources are supplied, which is known as the lag time.

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. During the log phase, the size of the bacterial colony increases dramatically. The log phase is what’s happening when your sour cream goes from white to green overnight. The third phase of bacterial cell growth is called the “stationary phase”.

However, microorganism growth also exhibits lag, stationary, and death phases under starvation conditions, in which cell growth is highly suppressed, while quantitative laws or theories for such phases are underdeveloped. Growth Curve. Since bacteria are easy to grow in the lab, their growth has been studied extensively. It has been determined that in a closed system or batch culture (no food added, no wastes removed) bacteria will grow in a predictable pattern, resulting in a growth curve composed of four distinct phases of growth: the lag phase, the exponential or log phase, the stationary phase, and the Growing microalgae for biolipid production usually involves a lag phase of growth followed by a stationary phase induced by some sort of “stress” This “stress”, often nitrogen depletion, induces a switch in the metabolism of the microalgae, which encourages the production of storage lipids in the form of triacylglycerides (TAGs) rather than cell division (Meng et al., 2009; Widjaja et Bacterial growth curves typically can be divided into four distinct phases: lag phase, log phase, stationary phase, and death phase. Drag the following descriptions to the appropriate location on the bacterial growth curve. 1- Log of the number of bacteria.
