1. A method for reducing a production of build-up slime of a papermaking material consisting essentially of a white water and a waste paper pulp in a papermaking process, comprising steps of:
inhibiting an adhesion between a slime-producing microorganism and additives during the papermaking process by adding a dispersing agent into the papermaking material to obtain a first mixture;
mixing and culturing the mixture;
adding an antagonist into the first mixture to obtain a second mixture;
mixing and culturing the second mixture for reducing the slime; and
re-adding said antagonist into the mixed and cultured second mixture after a specific time period for further reducing the slime, wherein said antagonist is a benefit microorganism being Streptomyces bikiniensis.
