Figure 2, plots a graph with A550 on the y axis and time of induction (min) on the x axis. The graph illustrated how the alleles tQ87am and tQ209am contain partial Holin activity. When the two alleles are present in the sample; the turbidity decrease indicating the bacteria has died, due to lysis activity. The alleles tQ87am and tQ209am supports gradual lysis after 40 min and 75 min, respectively.

Figure 6, contains a graph measuring the OD550 (optical density) over time (hours). The lines on the graph showed various lysis genes. These genes had a combination of mutant strains of xhylA (encodes for putative endolysin), xhlB (encodes for putative holin), or xlyA inject inside of them. According to the graph the lines with with solid triangles (POP1234), solid squares (SK109), and a hallow square (SK110) all decreased in turbidity. Since three of these cultures contained contained strains of either xlyA or xhlB; indicating the bacteria in the culture died due to lysis. This proves holin and endolysin play a major role in lysis.
