B. Tartakovsky et al., IMMOBILIZATION OF ANAEROBIC SLUDGE USING CHITOSAN CROSS-LINKED WITH LIGNOSULFONATE, Journal of industrial microbiology & biotechnology, 20(1), 1998, pp. 45-47
A new method for immobilization of anaerobic sludge in chitosan is des
cribed. It is based on the reaction of basic NH2 groups of chitosan wi
th the acidic sulfonic-groups of lignosulfonate to form sulfonilamide
linkages. The new procedure features simplicity, low-cost and mild imm
obilization conditions. Batch tests of acetate consumption along with
a continuous reactor operation confirmed the effectiveness of the immo
bilization technique for maintenance of long-term stability of the pol
ymer.
