Study the Effect of Some Physical and Chemical Agents on Growth of Enterobacter Sazkazakii Isolated from Local Foods

This research was performed to study the effect of some physical chemical material which found domestically in order to control the growth of E. sakazakii. The effect of different concentrations of NaCl exhibit that 3.5% of the salt killed the bacteria after 30 min of incubation, while the low concentration showed a less inhibition in numbers of cells. In using different concentrations of chlorine showed that 6% concentration was effective in killing the bacteria in 10 min, while 9% conc. destroyed the bacteria in 5 min. when using different conc. of citric acid reaching pH: 5 3 bacterial growth inhibited to low levels in comparing the control. And when we use NaOH to gain a pH: 9 11 bacterial growth were inhibited to 40 25 colony forming unit/ml after 30 min. of incubation
