Relationship between actual and predicted ammonia production using the PLS model. The concentration of ammonia produced by E. coli DH10B from four food by-products and six media containig amino acids was plotted against the concentration of ammonia predicted by PLS regression. The data of ammonia concentration are expressed as the mean values (n = 3), and the predicted ammonia production was calculated by PLS regression analysis using the data (n = 1) of the concentration of amino acids, sugars, and organic acids in the medium
