Growth kinetics of mixed culture in salmonella enrichment media

R hodes , P., Q uesnel , L.B. & C ollard , P. 1985. Growth kinetics of mixed culture in salmonella enrichment media. Journal of Applied Bacteriology 59 , 231–237. A technique for investigating the kinetics of salmonella enrichment is reported. Its use with four enrichment media (Rappaport' medium, Muller‐Kauffmann tetra‐thionate broth (MKT) tetrathionate broth and selenite F) is described and the effect of elevated temperature on the growth kinetics shown. Rappaport' medium at 37d̀C and MKT at either 37d̀C or 42d̀C were far superior to selenite F and tetrathionate broth in their selective properties and, with the exception of Rappaport' medium, the use of elevated temperature increased the selectivity of the media.
