Webb10 feb. 2024 · A strain of Staphylococcus simulans D14 (S. simulans D14) showed the highest nitrate reductase activity (NRA) of 4.52 mM NO2−/mg dry weight by the spectrophotometric method, which was screened from traditional Chinese sausage. When the UV mutagenesis time was 25 s, the positive mutation rate was the highest at 26.60%. … Webb1 maj 2001 · Tested strains were inoculated perpendicularly to the streak of a β toxin-producing Staphylococcus aureus [ 15 ]. Inoculated plates were incubated at 35°C for up to 3 days. The results were evaluated as antagonistic (β–α hemolysins) or synergistic (β–δ hemolysins) effects as determined by the shapes of hemolytic zones produced.
