The Lotka-Volterra predator-prey model

Model predictions
1. First, bacteria utilize the resource on which their population growth rate
µ
is highest, i.e., the resource with highest i S i
K i +S i
. At high concentrations
this ratio is approximately eqal to µ i .
2. Concentration of the preferred resource will decrease and at certain time
bacterial fitness on both susbstrates will be the same. Since that time
bacteria will utilize both substrates.
3. The switching time can be estimated from the model. The parameters
we need to know are only those that describe bacterial growth on a single
substrate.
