The purpose of this study is to provide a predictive model of Escherichia coli by selective growth factors such as heat storage (8 ° and 37 ° C) and PH (4, 5 and 6) in the extract was chicken business. For this purpose, a commercial extract of chicken prepared using acetic acid and 1/0 normal profit on the desired PH was adjusted. The level of 105 cfu / ml of the extract prepared from bacteria were inoculated. Extract in the temperature of 8 and 37 ° C and at a different time than the samples were measured. . The results are consistent with the expectation that the significant growth in the PH 4 (P <0/05), less than the growth of the PH 5 and 6, respectively. In contrast to the expected reduction in the temperature of 37 ° C and 8 ° C was observed. In other words, the bacteria grow in temperatures of 8 and 37 were the same.
