Zusammenfassung:	PURPOSE: To provide a method for producing regenerated paper, capable of improving the water filterability of the paper without deteriorating its strength by adding a fungus or bacterium having a pulp fiber-agglutinating action to a pulp slurry containing waste paper regenerated pulp and subsequently producing the paper from the mixed pulp slurry. CONSTITUTION: This method for producing regenerated paper comprises adding a prescribed amount of an imperfect fungus, Trichosporon fungus (FERM P-11960), having a pulp fiber-agglutinating action to a pulp slurry containing waste paper regenerated pulp and subsequently producing the regenerated paper from the mixed pulp slurry.
