Figure 3
Growth data as relative cell viable counts for C. piscicola and L. mesenteroides affected by different acids (points). Response surfaces show growth predicted by equation (1). X: growth quantified by ln (N/N0); C: acid concentration (mM); t: time (h). For clarity, confidence intervals (in all cases less than 5% of the experimental mean value; α = 0.05; n = 3) were omitted. Keys for bacteria are described in Table 7.
