<p>PURPOSE:To obtain an immobilized carrier having improved affinity to cells or microorganisms and suitable for bioreactor, culture medium, etc., by introducing a specific functional group to a surface of a carrier made of carbon or graphite. CONSTITUTION:One or more kinds of functional groups containing at least one element selected from oxygen, sulfur, halogen, hydrogen and nitrogen, preferably groups selected from hydroxyl group, carbonyl group, aldehyde group, carboxyl group and amino group are introduced to a surface of a preferably porous immobilization carrier made of carbon or graphite, e.g. carbon fiber, coke, carbon black, etc.</p> |
