Numerical taxonomy of microorganisms isolated from goat cheese made in Chile

118 strains of heterotrophic microorganisms were isolated from goat cheese produced domestically in the IV Region of Northern Chile (Serene, Ovalle, and Illapel) and sold in supermarkets in Valparaíso, Chile. The results of 89 phenotypic tests were numerically analyzed against 17 reference strains, using the simple matching coefficient (S(SM)). Thirteen phena were found at a 78% similarity level. Five of them (A, B, C, D, and E) were assigned to the family Enterobacteriaceae, phenon F was identified as belonging to the genus Aeromonas and strains of phenon G were assigned to the genus Acinetobacter. The other phena were identified as being members of the genera Bacillus (H, I, and J), Staphylococcus (K), Enterococcus (L), and Micrococcus (M). Approximately 19% of the isolates were Escherichia coli and 27%, Staphylococcus aureus.
