ABSTRACT:
Disclosed are a deterioration inhibitor for an emulsion-type processing oil comprising, as an active ingredient, a culture of a bacterial species selected from the group consisting of Aerococcus viridans BC-A-4 (Acceptance No. FERM BP-5041) and Bacillus brevis BC-A-69 (Acceptance No. FERM BP-5041) and Bacillus brevis BC-A-3124 (Acceptance No. FERM BP-5043) and a method for inhibiting deterioration of an emulsion-type processing oil comprising adding such deterioration inhibitor to the emulsion-type processing oil and then allowing the bacteria contained in the deterioration inhibitor to proliferate. Since the propagation of the putrefying bacteria in the emulsion-type processing oils can be suppressed by the proliferation of the bacteria contained in the deterioration inhibitor, the working life of the emulsion-type processing oil can be prolonged.
