The Growth Physiology

Growth Physiology :

What is Microbial GROWTH :

Living organisms grow and reproduce the growth indicates that an

organism is in active metabolism in plants & animals, we can see the

increase in height or size. Growth common refers to increase in size but with

microorganisms particularly bacteria, this term refers to changes in total

population rather than increase in size or mass of individual organisms. The

change in population in bacteria chiefly involves Binary fission.

                        Binary Fission

A cell dividing by binary fission is immortal unless subjected to stress by

nutrient depletion or environmental stress. Therefore, a single bacterium

continuously divides 1 cell divides and providing 2 cells and 2 cells divide

providing 4 cells and so on.Therefore, the population increases by geometric progression.

      Binary Fission Process Of Cell Division

The growth physiology includes the regulations rates of synthesis macromolecules regulation timing of DNA synthesis cell division physiological response to nutrient availability homeostasis (tendency of a system to safeguard internal stability)

adaptations to the external enivronment and the rates of biosynthetic pathways to the utilization of products for growth.

The sequence of growth phases through which a population of bacteria progresses when inoculated into Flask of fresh media.
