Kinetics Of Microbial Growth From A Thermodynamic Point Of View

In the previous sections, the full stoichiometric description of growth has been given from a unifying thermodynamic point of view. However, for a complete description, growth kinetics are also required. In this section these kinetics are also presented from a thermodynamic point of view.

A Basic Kinetic Description of Microbial Growth

In Figure 1, the typically observed batch-growth curves of a microorganism growing on one substrate (electron donor) are shown. In this section we use the subscript S to denote substrate (electron donor, D). Usually these curves are described (for constant batch volume) with two mass balances for substrate (donor) and biomass, giving two differential equations (DE):

Discover How To Become Your Own Brew Master, With Brew Your Own Beer. It takes more than a recipe to make a great beer. Just using the right ingredients doesn't mean your beer will taste like it was meant to. Most of the time it’s the way a beer is made and served that makes it either an exceptional beer or one that gets dumped into the nearest flower pot.
