New products are provided comprising inactivated lower eukaryotic cells, preferably yeasts or molds, having at the outer surface functionally active antibodies or functionally active fragments thereof. Preferred antibody fragments are the variable domains of Camelidae heavy chain antibodies, which are surprisingly stable against physical and chemical decontamination regimes and do not loose their activity when they are immobilized on the glucan layer of the cell wall which is present in a variety of lower eukaryotes. The new products are preferably in the field of food products, personal care products, and animal feed products.
