Abstract
The aim of this study was to determine the effects of different curing temperatures (4 °C or 10 °C) and agents (KNO3 orNaNO2) on microbiological and physicochemical properties of pastırma and diversity of gram-positive, catalase-positive cocci (GCC+)and also to investigate some technological properties of the strains. Four different groups of pastırma were produced applying differentcuring temperatures and agents. After production, GCC+ isolated from pastırma were subjected to phenotypic and genotypic (16S rRNAsequencing) identification. Genotypically characterized strains were evaluated for their technological properties. In all groups, aw andpH were observed to be under 0.90 and over 5.5, respectively. In genotypic identification, 45 isolates were identified as Staphylococcusvitulinus, while other isolates identified were S. equorum (n = 15), S. saprophyticus (n = 15), and S. xylosus (n = 12). All of the strainscould grow at different salt concentrations (8% and 15%) and temperatures (4 °C, 10 °C, and 37 °C). Four strains of S. saprophyticusshowed strong lipolytic activity while nine strains of S. vitulinus had strong proteolytic activity. This study showed that different curingtemperatures and agents are particularly effective on the microflora in pastırma; however, these factors do not cause a high diversity inGCC+ in terms of species.
