A comparative study on diauxic growth of microorganisms of Pseudomonas species

Abstract

Amongst the different microbial growth patterns, the bacteria growth has various types and diauxic growth is one of them. It is observed, when the bacteria switch from one to other source of energy when the primary source gets exhausted. Gene regulation is taking place in the bacteria DNA through which the message is conveyed to the gene to produce enzymes for the secondary energy source for digestion so as to keep the basic living conditions maintained. It varies from one to other prokaryotes. The bacteria considered for study were Pseudomonas species. A contrast is drawn in how these microbes show differences in their growth patterns based upon the variation in their growing mediums. Some shows differences on the basis of changing growth medium, some by changing temperatures and some by changing pH. By doing that, we will be able to draw a contrast between their differences in diauxic growths and can predict that before happening. The mathematical model for the P. denitrificans bacteria matches with the ideal model developed which proves that the growth being observed in different Pseudomonas species is diauxic in nature and can be used to predict the growth of the bacteria in the natural gas pipeline environment.
