Abstract
Immunostimulant products are prepared by adding lysozyme to a culture of L.bulgaricus at a pH of from 4-8 and then incubating the culture to hydrolyze peptidoglycans of cell walls of the bacteria. A suspension containing the lysozyme-treated L.bulgaricus is collected, which is centrifuged to obtain an immunostimulant supernatant. The supernatant may be filtered to obtain an immunostimulant solution, which may be added to a fermented milk, or to a whey, to prepare an immunostimulant product. Alternatively, L.bulgaricus may be cultured and hydrolyzed by lysozyme in a milk product to provide an immunostimulant milk product.
