A Effects of temperature and culture conditions in SA arginine metabolism. Schematic overview of arginine biosynthesis and degradation metabolism in SA. Genes with changes at 39 °C (both with a significant difference or a non-significant trend are indicated with color coded spots on the figure). B SA survival in CDM medium lacking arginine and proline and supplemented with 0.5% KNO3. Cultures were incubated under microaerobiosis for 2 h at 37 °C and further split and incubated at 37 or 39 °C for 2 h. CFU/ml was determined on TSA agar plates and compared by unpaired t-test
