Growth of staphylococci and streptococci in raw milk

Streptococci were found to grow better in raw milk with redox potential similar to that inside the udder than staphylococci. In these redox conditions in active milk containing about 10(6) somatic cells per 1 ml, both streptococci and staphylococci survive but only some strains grow. In aerobic conditions active milk inhibited the growth of streptococci more than that of staphylococci.
