The In Vitro Efficacy of Effective Microorganisms (EM) for Inhibition Of Salmonella enteritidis Gaertner(Thai)

Abstract

Three types of EM (effective microorganisms) were purchased from markets in Khon Kaen metropolis, Khon Kaen province. All of them were tested for total microbial count and pH. Only the best type of EM was selected for our research. This EM had total bacteria count and pH of 8.2 x 103 cfu/ml and 3.49 respectively. Inhibition effect of EM for Salmonella enteritidis Gaertner at 5.0 x 108 cfu/ml was 0.5% for 1 hour and 100% for S. enteritidis contaminated boiler faeces for 30 minutes.
