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

Adsorption properties of supports based on catalytic filamentous carbon (CFC) have been studied with respect to different substances of biological origin — amino acid (l-tyrosine), protein (bovine serum albumin), enzyme (glucoamylase) and non-growing cells of microorganisms (Eschericia coli, Bacillus subtilis, Rhodococcus sp.). The factors influencing the adsorption efficiency have been investigated. In particular, the effect of surface chemical properties 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.
