✦ Synopsis


Abstract

A study relating to the biological detoxification of resin acids is described. Abietic acid was transformed into a number of non‐toxic hydroxylated derivatives by Mortierella isabellina. The biotransformation products have been identified and shown to be less toxic than abietic acid.
