Growth kinetics of mixed culture in salmonella enrichment media.
A technique for investigating the kinetics of salmonella enrichment is reported. Its use with four enrichment media (Rappaport's medium, Muller-Kauffmann tetrathionate broth (MKT) tetrathionate broth and selenite F) is described and the effect of elevated temperature on the growth kinetics shown. Rappaport's medium at 37 degrees C and MKT at either 37 degrees C or 42 degrees C were far superior to selenite F and tetrathionate broth in their selective properties and, with the exception of Rappaport's medium, the use of elevated temperature increased the selectivity of the media.
