“…However, to date, only a few reports have specifically compared the capacity of fungus and activated sludge particularly in relation to TrOC (Hai et al, 2012) or other persistent compounds (Hai and Yamamoto, 2010). As an additional notable omission, the relative contribution of biosorption and biodegradation during fungal removal of TrOCs remains largely unexplored (Cravotto et al, 2008, Hai et al, 2012 although several studies have reported that biosorption plays a significant role in removal of TrOCs by activated sludge (Cirja et al, 2008, Tran et al, 2009, Yang et al, 2011.…”

The resistance of certain anthropogenic trace organic contaminants (TrOCs) to conventional wastewater treatment and their potential adverse effects on human and ecological health raise significant concerns and have prompted research on their bioremediation by white-rot fungi. This study compared the removal efficiencies of four widespread TrOCs: carbamazepine (CBZ), sulfamethoxazole (SMX), bisphenol A (BPA) and diclofenac (DCF), by nitrifying activated sludge as well as whole-cell and extracellular enzyme (laccase) extract of the white-rot fungus Trametes versicolor. Fungal whole-cell culture removed only BPA and DCF but with high efficiencies (>90%) while the mixed nitrifying culture removed all compounds, although by levels of only 5-40%. Rapid initial sorption on fungal mycelium (44 ± 13% for DCF) was observed; however, biodegradation governed the overall removal. Performance comparison between fungal whole-cell and extracellular extract revealed that, unlike BPA, a catalytic pathway independent of extracellular laccase was responsible for DCF removal. Addition of mediator (1-hydroxybenzotriazole) to extracellular extract improved the removal of SMX which bears an electron donor group, but not that of the resistant compound CBZ.

“…The use of ultrasound to destroy nonylphenols is not common, and the literature is limited to a couple of studies describing the degradation of alkyl phenols by 220 kHz ultrasound [12] and that of nonylphenol by a hybrid process involving oxidation by sono-Fenton reaction followed by fungal biosorption [13].…”

“…It is known that both bacterial and fungi are important in degrading pollutant chemicals (Radwan 2008 ), with basidiomycete fungi and bacteria having the ability to degrade polyphenolics (Gadd 2004 ;Cravotto et al 2008 ), with some fungi being able to use volatile aromatic hydrocarbons as their sole energy source (Prenafeta-Boldú et al 2001a , b ), however the presence of ectomycorrhizae appears to suppress the decomposition of PAHs (Joner et al 2006 ). Mycorrhizal fungi are important players in the rhizosphere enabling both heavy metals (Sessitsch and Puschenreiter 2008 ) and radionuclides to be retained in the fungal structure and limiting uptake into plants and the fruit bodies of ectomycorrhizal species have been shown to be hyperaccumulators of both metals and radionuclides (see reviews by Leyval et al 2002 ;Dighton 2009a , b ;Dighton et al 2008 ).…”

Interactions in Soil: Promoting Plant Growth

View full text Add to dashboard Cite

Soil is a complex milieu of physical and biological entities that regulates the availability of nutrients for plant growth. The interactions between the elements of the soil biota and the plants during this process are complex and often rely on feedbacks between the plants and the great diversity of soil organisms that function to regulate processes to support plant growth. The rhizosphere and its mycorrhizal component are important parts of the connection between the plant and soil through its roots. This zone is a 'hot-spot' of microbial activity and trophic interactions with other soil organisms. It is here that growth of the plant root is infl uenced by nutrient availability, induction of root growth stimulating auxins, the interaction with plant pathogens and herbivores. Ecosystem engineers in the form of earthworms and other burrowing fauna are important in altering both the physical structure of soil and rates of decomposition of organic residues. A little researched component of soil is viruses. Their interaction with microbial and faunal communities is introduced here. Many of the soil processes infl uencing plant growth and the diversity of soil organisms is infl uenced by human activities ranging from agricultural and forestry practices through urbanization to the infl uence of pollution from industrial processes. To help us with the understanding of the interactions between biodiversity and function, new molecular tools involving metagenomics and transcriptomics are evolving, and are discussed here as an emerging suite of tools that can be applied to soil ecology. The chapter introduces the detail to come in subsequent chapters of this book.
