Washing- or cleaning agent comprises: (a) at least a hydrolytic enzyme, preferably a protease (preferred), amylase, cellulase, hemicellulase, mannanase, tannase, xylanase, xanthanase, beta -glucosidase, carrageenase or a lipase; (b) at least a substance, which improves the synergistic cleaning performance in combination with the component (a). The substance (b) is (b1) amino acid or polyamino acid or its derivative, (b2) bio-surfactant, (b3) microbial metabolite and/or (b4) preparation of a microbial culture supernatant and contains at least 2.5 wt.% of one of the substances from b1 to b3.
