Abstract
The effects of pH and concentration of lactic or acetic acids on the growth of seven Enterobacteriaceae bacteriaceae strains (S. enteritidis, E. coli, C. freundii, K. aerogenes, P. vulgaris, E. cloacae and S. liquefaciens) were investigated.
The results were sum m arized as fllows;
(1) The inhibitory effect of lactic acid on the grow th of S. enteritidis, E. coli, C. freundii, K. aerogenes, P. vulgaris and E. cloacae was recognized at the final concentration of 0.05%(pH 5).
(2) The inhibitory effect of acetic acid on the growth of all the strains examined was recognized at the final concentration of 0.05% (pH 5).
