Hello,
I just started using GWB React to simulate microbial metabolism and growth. The general form of GWB's Built-in Rate Law is shown below. I am wondering how it is written in GWB. For example, for the reaction
, its dual Monod equation is 
. The plot shows no microbial growth after running when I write down the equation for 'Kinetic microbe 1' in 'rate law' box of 'Reactants' pane as
(rate_con * activity("CH3COO-")/(activity("CH3COO-")+KD) * activity("SO4--")/(activity("SO4--")+KA) * ( 1 - (Q/K)^(order1) * exp(-(order1)*ATP_number*ATP_energy/R/TK))^(order2) * growth_yield - decay_con)*biomass
Does anyone know what is wrong with this expression?
Thanks！
