ABSTRACT:
A bacterial composition including in admixture a lactic acid producing bacterium which produces diacetyl, particularly Streptococcus lactis subspecies diacetylactis and a Pediococcus which generates an antimicrobial metabolite at refrigeration temperatures which is used to inhibit psychrotrophic bacteria in a milk or cream based product without fermentation or significant increase in cell count is described. The composition preferably uses a Pediococcus pentosaceus which generates hydrogen peroxide as the metabolite.
