Abstract
Cellobiose dehydrogenase purified from two different fungal sources was assessed for its ability to remove and/or reduce colour from pulp mill bleach plant effluent. Cellobiose dehydrogenase purified from Phanerochaete chrysosporium was shown to prefer acidic conditions and was consequently used to treat the acid effluent stream discharged from a pulp mill bleach plant, while an analogous enzyme originating from Humicola insolens preferred alkaline conditions, and was applied to the effluent discharged from the caustic sewer of the bleach plant. Both enzyme preparations were able to remove colour from their respective effluent sources to a comparable extent. Up to 50% of the effluent colour was removed within 4 days when treated under optimised conditions. Furthermore, it was also shown that this enzymatic approach was effective at removing colour generated by both softwood and hardwood resources. Mechanistically, it was shown that colour was removed from all molecular weight fractions, and the higher molecular weight material (>300 kDa) was concurrently preferentially degraded. Cellobiose dehydrogenase treatment of effluent did not target phenolic, stilbene, or alpha-carbonyl structures, but did affect the quinone content. Further investigations using model compounds confirmed these results, and subsequently showed that only the para-quinones with low substitution were reduced with cellobiose dehydrogenase.
