Fumes from phospholipids pyrolyzed at 500-700°C did not themselves show any mutagenicity on Salmonella strains, but when the pyrolyzates were treated with a sodium chloride precipitate, active carbon, or an anionic exchange resin, the filtrates were found to be mutagenic on Salmonella TA 100. Tests confirmed that the phospholipid pyrolyzates contained both mutagenic and inactivating substances of this mutagenicity. Low level mutagenieity was produced on Salmonella TA 98, but there was no such activity on the other strains. Preincubation of the pyrolyzates with S-9 mix had no activating effect on mutagenicity. The inactivating substances of the mutagenicity were isolated and identified as long chain fatty acids.
