Table 7.4
The results below were obtained from a use-dilution test of two disinfectants.Cultures were inoculated into tubes with varying concentrations of disinfectants and incubated for 24 hours at 20°C,then subcultured in nutrient media without disinfectants.
(+ = growth;- = no growth)

- In Table 7.4,what is the minimal bacteriostatic concentration of each disinfectant? Which compound is bactericidal? At what concentration?
