Studies related to biological detoxification of kraft pulp mill effluent. IV. The biodegradation of 14-chlorodehydroabietic acid with Mortierella isabellina

Article abstract of DOI:10.1002/hlca.19820650503

One of the fish-toxic chlorinated resin acids, 14-chlorodehydroabietic acid, found in kraft mill effluent is examined. When exposed to the fungus Mortierella isabellina, 14-chlorodehydroabietic acid is converted into a number of hydroxylated derivatives which show low levels of toxicity to fish. These biotransformation products were isolated and characterized.
