Lipid peroxidation is a possible oxidative process of lignin-degradation at a site far from the enzymes by selective white rot fungi. Production and peroxidation of saturated and unsaturated fatty acids by Ceriporiopsis subvermispora strongly suggests involvement of lipid peroxidation in its ligninolytic system. In this paper, a new aliphatic lipid-related fungal metabolite was isolated from wood meal cultures of C. subvermispora and its chemical structure was fully identified. The novel compound was identified as (Z)-1,7-nonadecadiene-2,3-dicarboxylic acid, an itaconic acid derivative linking a hydrophobic hexadecenyl group at the C-3 position of the core structural unit.
