R2 and Fisher test results (with the relative P value) are also reported. Salt, NaCl concentration; Glucose, glucose concentration; Temp, fermentation temperature.
-, coefficient with P < 0.05 excluded from the final model.
The existence of too many undetectable values of the dependent variable did not allow us to obtain a model for tyramine at days 3 and 5.
