Input Editor Pane Microbial Reactions

In this pane all parameters for microbial (Monod kinetic and microbial transfer, i.e. between aqueous and adsorbed phase) reactions are set.

The name of the reaction serves as a descriptive identifier and must be unique.

The type of a reaction cannot be changed after it was set up.

Adding and removing microbial reactions

A new microbial reaction can be added by invoking the "Add new reaction" button. A dialog box will appear that requires the input of the name and the type (Monod kinetic or microbial phase transfer) of the reaction. Pressing Cancel or closing the window will abort the addition of the new reaction.
Note: The newly added reaction is initially invalid. You will have to add at least one reactant and product species to make it a valid reaction.

The selected reaction can be removed by invoking the "Remove selected reaction" button.
Note: No confirmation for the removal of the selected reaction is required. All data of this reaction will be lost once the button is activated.

Modifying the parameters for the selected microbial reaction

In the lower half of the input pane the parameters for the selected reaction are displayed.

The substrate, electron acceptor, and nutrient are selected between the species that are participating in this reaction. They do not have to be assigned.

The inhibitor species can be any of the chemical species present in the simulation.

The stoichiometric coefficients for reactants and products are modified in the two tables at the bottom of the pane. Stoichiometries are given in terms of species.

Adding and removing reactants and products of the selected reaction

Reactants and products can be added and removed by using the four buttons above the two tables. Microbiological reactions may involve any chemical species as reactants and products. One reactant may be identified as the substrate, one as the electron acceptor, one as the nutrient. The substrate, electron acceptor, and nutrient species can not be removed from the list of reactants. You must first assign a different substrate etc. (including "none" as possible option) before you can remove the reactant. Any chemical species can be the inhibitor in the Monod kinetic expressions.
