Title:
MICROBIAL CELL ADSORBENT TO WHICH MULTIVALENT CATIONIC SUBSTANCE IS BONDED, AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2016/114280
Kind Code:
A1
Abstract:
To develop a material (antimicrobial material) in which an antimicrobial substance such as polyethylenimine or a multivalent cationic antimicrobial agent is caused to bond to a water-insoluble carrier in a stable form, the material removing, by adsorption, microbial cells in an aqueous solution continuously over a long period of time. Provided are: a microbial cell adsorbent which is a conjugate obtained by causing polyethylenimine having a molecular weight of 200-1,000,000 to bond to a water-insoluble carrier, the conjugate adsorbing microbial cells; and a method for manufacturing the microbial cell adsorbent. Also provided are: a microbial cell adsorbent which is a conjugate obtained by causing a multivalent cationic antimicrobial agent to bond to a water-insoluble carrier, the conjugate adsorbing microbial cells; and a method for manufacturing the microbial cell adsorbent.
