Figure 4: Comparison of viability between immobilized cells and cells in suspension after dynamic adsorption and desorption using 1% Triton X-100. The materials used were PEI and GA modified cotton, polyester, nylon and polyurethane. Symbols: CT = cotton, PE = polyester, NL = nylon, PUF = polyurethane foam. (a) adsorption and (b) desorption of S. cerevisiae 468/ pGAC; (c) adsorption and (d) desorption of S. cerevisiae 468.
