1. the phase Lag is a term that entered bacteria into meal as fuel that bacteria will adapt to the new environment. How many bacteria did not increase because Wang is not split cells, but the cells to synthesize and wong Wai Protocol and a new boss, as well as enzymes and enzymatic DNA RNA so that sufficient biochemical processes of the cell, there is a high bacterial Physiology activities. The size of the cells is increased, mainly to increase the length and dry weight, protein and are added by the end of this phase, bacteria will break, but because of all the bacteria did not split at the same time. Therefore, the population gradually increased.The length of the lag phase, the phase long enough, depending on the environment and the types of bacteria, such as if it were a type of bacteria that feed on the same type of food culture. Lagphase term is short, or if we put the fuel ready to split. In the short term, the new food into the lagphase, but if the fuel or fuels stored for a long time, it will take a long time to adapt to the new environment.2. Logarithmic phase, or Exponential phase, or Log phase is phase, bacteria break the fast in the fixed-rate is to divide each cell will take equally. In this phase, the growth rate of most. Wong Wai as cell. Nutrients will be used significantly and quickly. Dividing cells are associated with each protocol synthesis and absorption of the chemical activity of bacteria. The number of bacteria will increase two times, the nature of the curve is exponential.3. Stationary phase bacteria stage there will be a maximum number of constant and no longer is adding even more choices are divided, but will be equal to the death rate. This is because the nutrients are consumed almost all the information and is subject to expulsion of toxic waste out of the metabolism process.4. Death phase or the Decline phase is the phase where the bacteria will die quickly, and die more frequently until it is exponential and logarithm may be cause of death because the nutrients that feed the cells disappear and the accumulation of waste and toxins resulting from the metabolism process. Bacteria have different death rate depends on the type of bacteria, such as they are spherical GSM delete very fast dying within 2-3 days, and the rest of the cells alive, very little. Some types of infection to death slowly, making it a living bacteria remains as long as several months.
