Microsomal lipid peroxidation.
This chapter discusses microsomal lipid peroxidation, a complex process known to occur in both plants and animals that involves the formation and propagation of lipid radicals, the uptake of oxygen, a rearrangement of the double bonds in unsaturated lipids, and the eventual destruction of membrane lipids. Expand
Oxidation of persistent environmental pollutants by a white rot fungus.
Model studies suggest that the ability of Phanerochaete chrysosporium to metabolize these compounds is dependent on the extracellular lignin-degrading enzyme system of this fungus. Expand
Role of metals in oxygen radical reactions.
Factors such as pH and chelation govern the reactivity of the transition metals with dioxygen and "oxy-radicals" and therefore influence the apparent mechanisms by which oxidative damage to phospholipids, DNA, and other biomolecules is initiated. Expand
The requirement for iron (III) in the initiation of lipid peroxidation by iron (II) and hydrogen peroxide.

Using Fe2+, H2O2, and phospholipid liposomes as a model system, it is found that lipid peroxidation, as assessed by malondialdehyde formation, is not initiated by the hydroxyl radical, but rather requires Fe3+ and Fe2+. Expand
Transition metals as catalysts of "autoxidation" reactions.
The quantum mechanic, thermodynamic, and kinetic aspects of the reactions of dioxygen with biomolecules; the involvement of transition metals in biomolecule oxidation; and the biological implications of metal catalyzed oxidations are discussed. Expand
Biodegradation of azo and heterocyclic dyes by Phanerochaete chrysosporium
Biodegradation of Orange II, Tropaeolin O, Congo Red, and Azure B in cultures of the white rot fungus, Phanerochaete chrysosporium, was demonstrated by decolarization of the culture medium, theExpand
Biodegradation of pentachlorophenol by the white rot fungus Phanerochaete chrysosporium
Biodegradation of PCP was decreased in nutrient nitrogen-sufficient cultures of P. chrysosporium, suggesting that in addition to the lignin-degrading system, another degradation system may also be responsible for some of the PCP degradation observed. Expand

The results demonstrate that the pathway for DDT degradation in P. chrysosporium is clearly different from the major pathway proposed for microbial or environmental degradation of DDT. Expand
