Growth kinetics of M. marburgensis during the THpN2fix methodology experiment without Na2CO3 in the medium and at different NH4+ concentrations in relation to original media composition (n = 4). Due to undercutting the THpN2fix in all four replicates of 5% NH4+ experiments at two subsequent time points, growth could not be monitored further since the method of destructive sampling has been employed for verifying THpN2fix independently twice through GC measurements.
