Expression of bioluminescence in Salmonella serovars. The theoretical amount of bioluminescence produced per CFU of each Salmonella serovar following 16 hrs of growth was calculated. Bioluminescence per cfu was calculated by dividing the background subtracted bioluminescence value (in p/s/cm2/sr) in each well by the number of bacteria (determined by serial dilution and plate counts). The mean and standard error from four replicates were then determined for each strain. Light emission was almost 12 fold higher in S. Newport as compared to S. Schwarzengrund.
