摘要：

The relationship between maximum specific growth rates (mu(max)) determined from viable counts and turbidimetric measurements for a range of bacterial species is examined in order to assess the potential of turbidimetric methods in predictive microbiology. Two methods for the estimation of mu(max) from turbidimetric data are presented. One is based on absorbance and the other on transmittance measurements. Both are compared to estimates obtained by viable count methods. Calibration factors, a function to correct the non-linearity of absorbance measurements, and for viable count data, are determined. It is concluded that turbidimetric measurements may be used reliably for estimation of mu(max).
