From Table 3, it can be seen that bacterial growth is inhibited if it does not reach the optimum temperature (37 °C). This growth is further hampered by the presence of Puristic and Virus Shut Out that act as disinfectants. Even though the Puristic's disinfection process was not as significant as it was at 37 °C, the decrease in bacterial growth in this experiment occurred in almost all the bacteria used. From this experiment, it can also be seen that the performance of Puristic and Virus Shut Out as a disinfectant was affected by the temperature and the content of the disinfectant itself.
