摘要

Bioactive agents consisting of one or more lactoferrin-compounds selected from the group consisting of Zn-, Cu- and Mn-lactoferrin and having selective biological activities, i. e. growth-inhibitory activity against certain harmful microorganisms on one head and growth-promoting activity upon certain useful microorganisms on the other hand; as well as compositions, products or materials therefor comprising the bioactive agents consisting of one or more lactoferrin-compounds selected from the group; and a method for treating materials, which are edible for humanbeings or animals or which are applicable to a portion of body of humanbeings or animals, with the bioactive agents consisting of one or more lactoferrin-compounds selected from the group consisting of Zn-, Cu- and Mn-lactoferrin or the compositions comprising the bioactive agent consisting of one or more lactoferrin-compounds selected from the group consisting of Zn-, Cu- and Mn-lactoferrin as an effective component.
