Growth and proteolytic activity of P. gingivalis strains in nutrient-rich broth. a Growth of strains [33F (filled triangle), W50 (open circle) and SUB1 (filled diamond)] in BHI over time was assessed as absorbance at 600 nm and the graph shows mean ± SD of three independent biological replicates. b Proteolytic activity over time as assessed using a FITC-conjugated gelatin substrate and expressed as trypsin equivalent units (TEU). The graph shows mean ± SD of the same three independent biological replicates in a. c Aliquots from the cultures on day 3 were subjected to zymography on gelatin-containing gels stained with Coomassie brilliant blue. All samples were run on the same gel and the image has not been subject to digital enhancement or bands removed by cropping. The original image is available in Additional file 1
