Catalytic filamentous carbons for immobilization of biologically active substances and non-growing bacterial cells

Adsorption properties of supports based on catalytic filamentous carbon (CF C) have been studied with respect to different substances of biological ori gin - amino acid (L-tyrosine), protein Bovine serum albumin), enzyme (gluco amylase) and non-growing cells of microorganisms (Eschericia coli, Bacillus subtilis, Rhodococcus sp.). The factors influencing the adsorption efficie ncy have been investigated. In particular, the effect of surface chemical p roperties and textural parameters on the adsorption has been studied. Three independent methods have been suggested for determining accessible surface area for adsorbate molecules of different size. (C) 2001 Elsevier Science Ltd. All rights reserved.
