Biodegradation of chitosan (in English)
Chitosan has been found to undergo readily to biodegradation in an aqueous medium. In this study chitosan was degraded by microorganisms from an activated waste-water sludge produced by a cellulose plant. The molecular structures of chitosan were determined by using GPC in 2, 4 and 8 weeks of treatment. Full degradation was found to have occurred in a 12-week treatment. The process of the biodegradation of chitosan can also be monitored by using IR spectrophotometry.
