Figure 3

Proteolytic activities of S. marcescens CSM-RMT-1 and CSM-RMT-II-1 strains after 24, 48 and 120 h of incubation at three different (20, 25 and 30 °C) temperatures. Sizes of clearing zones are mean values of three parallel measurements. The bars indicate the standard deviation of three replicates of the experiment. Different upper-case letters between the incubation times indicate a significant difference between the clearing zone within the same strain according to Games–Howell post hoc tests (α = 0.05).
