Bacteria were identified from homogenized milk before and after pasteurization at 15 different combinations of temperature and time, and at spoilage after storage at 3 and 7 deg C. The initial microflora were dominated by coryneforms, with some Gram positive cocci and low proportions of Bacillus. Increased severity of pasteurization reduced proportions of G+ cocci; but at the end of shelf life, all treatments were dominated by Bacillus circulans.
