Abstract Using the traditional Chinese fermented sausages as sample, the experiment isolated the
Gram-positive and touch-positive staphylococcus, and purified strains that was carried out by crossing
plate method. A series experiments were maked out of to choose the bacteria which didn;t product
mucilage, gas, color ,H2S,ammonia, didn’t bear the decarboxylase, could reduce nitrate at 15℃ and
could grow when the pH were 4.5. Biolchemical appraisal proved that the bacteria possess the qualifications
mentioned above were the excellent staphylococcus in ferment sausage. Finally, detected the growth
curve and pH changes curve of 24 hours of the several advantage strains.
