Separate mathematical models for each of six bacteria that related organic acid minimum inhibitory concentrations (MICs) to the principal properties of the acids were previously constructed. MICs were determined for eight selected acids for four additional bacteria (Listeria innocua, Listeria ivanovii, Pseudomonas aeruginosa and Oenococcus oeni) and MIC models for each organism were constructed. These were very strong, with R2 values ranging from 0.905 to 0.947. The patterns of the MIC model coefficients were compared with those of the six bacteria models constructed previously. Together these represent a pattern of acid susceptibility and four different patterns of acid resistance (Lactobacillus-type, E. coli-type, Listeria-type and Pseudomonas-type).
