Feasibility of bioremediation by white-Rot Fungi.
Applied microbiology and biotechnology, 2001Co-Authors: S B PointingAbstract:The ligninolytic enzymes of white-Rot Fungi have a broad substrate specificity and have been implicated in the transformation and mineralization of organopollutants with structural similarities to lignin. This review presents evidence for the involvement of these enzymes in white-Rot fungal degradation of munitions waste, pesticides, polychlorinated biphenyls, polycyclic aromatic hydrocarbons, bleach plant effluent, synthetic dyes, synthetic polymers, and wood preservatives. Factors relating to the feasibility of using white-Rot Fungi in bioremediation treatments for organopollutants are discussed.

White Rot Fungi and their role in remediating oil-contaminated soil
Environment International, 1998Co-Authors: A. Yateem, M.t. Balba, N. Al-awadhi, A. S. El‐nawawyAbstract:White Rot Fungi, which utilize lignin as an energy source, possess the ability to degrade a wide spectrum of environmental pollutants using peroxidases enzymes. This ability led to several studies that focused on the development of bio-treatment systems using white Rot Fungi. Three strains of white Rot Fungi, namely Phanerochaete chrysosporium, PleuRotus ostreatus, and Coriolus versicolor, have been tested for their ability to degrade oil in contaminated soil. A soil microcosm test was designed to study the effect of strain used, inocula concentration, and the addition of nitrogen on bioremediation efficiency. Coriolus versicolor showed the highest degradation rate, as the total petroleum hydrocarbon (TPH) concentration decreased from 32 g/kg to reach 7 g/kg within 12 months. The increase in the inocula concentration enhanced substantially TPH degradation. The nutrient rich conditions initiated the growth of other soil existing microorganisms enabling them to degrade different compounds synergistically with some white Rot fungal strains. Because of their unique biodegradative abilities, white Rot Fungi are considered potentially useful microorganisms for bioremediation applications.

Biodegradation of Different Genotypes of Miscanthus by Wood Rot Fungi
BioResources, 2016Co-Authors: Paul W. Baker, Ana Winters, Michael HaleAbstract:Miscanthus, which is comprised of several different genotypes, is an important high-biomass crop with applications in the biofuel industry and in the formation of biocomposite materials. The overall composition of Miscanthus can be altered via degradation with wood Rot Fungi. The starting composition revealed that the cellulose content of Miscanthus x giganteus was higher than that in Miscanthus sacchariflorus and that the lignin contents were similar in both genotypes. Of the wood Rot Fungi, only Lentinus edodes appeared to have completely colonized M. sacchariflorus and showed significant degradation. In contrast, all of the brown Rot Fungi showed partial colonization of both Miscanthus genotypes and had little effect on the fibrous composition. Cellulose degradation by some white Rot Fungi increased with cellulose content whereas cellulose degradation by other Fungi was independent of cellulose content. All of the white Rot Fungi showed similar rates of lignin degradation, except for PleuRotus ostreatus, which was higher on M. sacchariflorus. The effect of the moisture contents of Miscanthus on cellulose and lignin decomposition by Phlebiopsis gigantea SPLog6 and Coniophora puteana 11E was also investigated. These results revealed subtle differences in the growth of white Rot Fungi on different Miscanthus genotypes.

Increased delignification by white Rot Fungi after pressure refining Miscanthus.
Bioresource technology, 2015Co-Authors: Paul W. Baker, Adam Charlton, Michael HaleAbstract:Pressure refining, a pulp making process to separate fibres of lignocellulosic materials, deposits lignin granules on the surface of the fibres that could enable increased access to lignin degrading enzymes. Three different white Rot Fungi were grown on pressure refined (at 6 bar and 8 bar) and milled Miscanthus. Growth after 28 days showed highest biomass losses on milled Miscanthus compared to pressure refined Miscanthus. Ceriporiopsis subvermispora caused a significantly higher proportion of lignin removal when grown on 6 bar pressure refined Miscanthus compared to growth on 8 bar pressure refined Miscanthus and milled Miscanthus. RM22b followed a similar trend but Phlebiopsis gigantea SPLog6 did not. Conversely, C. subvermispora growing on pressure refined Miscanthus revealed that the proportion of cellulose increased. These results show that two of the three white Rot Fungi used in this study showed higher delignification on pressure refined Miscanthus than milled Miscanthus.

The potential for white-Rot Fungi in the treatment of pollutants
Current Opinion in Biotechnology, 1995Co-Authors: C. Adinarayana ReddyAbstract:Abstract Lignin-degrading white-Rot Fungi have the unique ability to degrade/mineralize a broad spectrum of structurally diverse toxic environmental pollutants. Extracellular peroxidases are important in degrading some, but not all, xenobiotic compounds. More research is needed to realize the potential of white-Rot Fungi in field-scale applications. Recent progress in our knowledge of the biochemistry and molecular biology of the key enzymes involved in xenobiotic degradation should pave the way for the eventual development of rational and enhanced bioremediation strategies.

Bioremediation of quinolin-contaminated soil by white Rot Fungi
Environmental Pollution & Control, 2011Co-Authors: Qu JingjingAbstract:White Rot Fungi PleuRotus ostreatus was selected to degrade quinoline in simulated soil,and the effect of soil moisture,Fungi inoculum size,soil pH and wood dust on degradation efficiency was investigated.Results showed it was feasible to bioremediation quinolin-contaminated soil by white Rot Fungi.The removal rate of quinoline was increased with increasing the soil moisture,higher inoculim size of Fungi resulted in a higher degradation rate of quinoline,while soil pH had little effect on quinoline degradation.Addition of wood dust could promote quinoline degradation for it provided nutrition source to white Rot Fungi.The mechanism of quinoline degradation by white Rot Fungi still needed further exploration and study.
