Comparing the antimicrobial effectiveness of NaCl and KCl with a view to salt/sodium replacement.

Bidlas, Eva; Lambert, Ronald J. W. (Elsevier, 2008-05-10)

A study using a small range of pathogenic bacterial species (Aeromonas hydrophila, Enterobacter sakazakii, Shigella flexneri, Yersinia enterocolitica and 3 strains of Staphylococcus aureus) has shown that potassium chloride ...
An explanation for the effect of inoculum size on MIC and the growth/no growth interface.

Bidlas, Eva; Du, Tingting; Lambert, Ronald J. W. (Elsevier, 2008-08-15)

The inoculum effect (IE) is the phenomenon observed where changes in the inoculum size used in an experiment alters the outcome with respect to, for example, the minimum inhibitory concentration of an antimicrobial or the ...
Growth curve prediction from optical density data

Mytilinaios, Ioannis; Salih, Magdi; Schofield, Hannah K.; Lambert, Ronald J. W. (Elsevier Science B.V., Amsterdam., 2012-03-15)

A fundamental aspect of predictive microbiology is the shape of the microbial growth curve and many models are used to fit microbial count data, the modified Gompertz and Baranyi equation being two of the most widely ...
An improved model for the analysis of combined antimicrobials: a replacement for the Chou‐Talalay combination index method

Anastasiadi, Maria; Polizzi, Karen; Lambert, Ronald J. W. (Wiley, 2017-10)

Aims To rationalise confusion in the literature concerning the analysis of combined antimicrobials, specifically to see if the combination index (CI) method of analysis was as rigorous as claimed. Methods & ...
Modelling of bacterial growth with shifts in temperature using automated methods with Listeria monocytogenes and Pseudomonas aeruginosa as examples

Salih, Magdi; Mytilinaios, Ioannis; Schofield, Hannah K.; Lambert, Ronald J. W. (Elsevier Science B.V., Amsterdam., 2012-04-02)

Time to detection (TTD) measurements using turbidometry allow a straightforward method for the measurement of bacterial growth rates under isothermal conditions. Growth rate measurements were carried out for Listeria ...
Monte Carlo simulation of parameter confidence intervals for non-linear regression analysis of biological data using Microsoft Excel.

Lambert, Ronald J. W.; Mytilinaios, Ioannis; Maitland, Luke; Brown, Angus M. (Elsevier Science B.V., Amsterdam., 2012-06-18)

This study describes a method to obtain parameter confidence intervals from the fitting of non-linear functions to experimental data, using the SOLVER and Analysis ToolPaK Add-In of the Microsoft Excel spreadsheet. ...
A new model for the effect of pH on microbial growth: an extension of the Gamma hypothesis

Lambert, Ronald J. W. (Blackwell Publishing Ltd, 2011-01-31)

Aims: To investigate the appropriateness of the extended Lambert-Pearson model (ELPM) to model the effect of pH (as hydrogen and hydroxyl ions) over the whole biokinetic pH range in comparison with other available models. ...
