ESCHERICHIA COLI PROLIFERATION INHIBITOR, TOILET SAND FOR PETS USING THE SAME, AND METHOD FOR INHIBITING PROLIFERATION OF ESCHERICHIA COLI

摘要

PROBLEM TO BE SOLVED: To provide an Escherichia coli proliferation inhibitor and a method for inhibiting proliferation of Escherichia coli, which are simpler and more easily used.SOLUTION: The Escherichia coli proliferation inhibitor according to one aspect of the invention includes limonite. In this case, the limonite is preferably one which contains not less than 60 pts.wt. to not more than 80 pts.wt. of Fe oxide, not less than 8 pts.wt. to not less than 18 pts.wt. of SiO, not less than 1 pt.wt to not more than 5 pts.wt. of AlO, and not less than 0.1 pt.wt. to 2 pts.wt. of CaO when the total amount of limonite is 100 pts.wt. The method for inhibiting proliferation of Escherichia coli according to another aspect of the invention comprises adding limonite to a medium to be processed and mixing them. In this case, the limonite is preferably contained in an amount of 1 pt.wt. or more when the total weight of the medium to be processed and limonite is 100 pts.wt.
