Growth substrate selection and biodegradation of PCP by New Zealand white-rot fungi

Physiological Characterization of Fungal Inoculum for Biotechnological Remediation of Soils

“…The capacity of basidiomycetes to degrade chlorophenols, including pentachlorophenol as already reported in literature (Okeke et al 1997;Ullah et al 2000;Seradati et al 2003;Machado et al 2005a;Soares et al 2011) was proved here. There are difficulties to use the concentrations above 200 mg kg -1 pentachlorophenol, given the basidiomycetes' sensibility to the pollutant (Leontievsky et al 2001;Ahn et al 2002;Walter et al 2004). Hence, the use of L. crinitus CCIBt2611 could be promising as it demonstrated efficacy in the treatment of pentachlorophenol in the same concentration range.…”

Decolorization of methylene blue by new fungus: Trichaptum biforme and decolorization of three synthetic dyes by Trametes hirsuta and Trametes gibbosa

“…Therefore, several investigations have been carried out several investigations to identify a cost effective and environmentally acceptable technology that could be applied to remediate the contamination. Bioremediation is one of these techniques that involve almost exclusively microbial processes [20][21][22][23]. White rot fungi have been studied as one of the possible agents of biodegradation since their extracellular degradation systems are basically non-specific.…”

Bioremediation of a Chilean Andisol contaminated with pentachlorophenol (PCP) by solid substrate cultures of white-rot fungi

“…White-rot fungi are of particular interest due to their ability to degrade a wide range of environmental pollutants such as polycyclic aromatic hydrocarbons (PAHs), numerous synthetic dyes, chlorophenols, among others (Lamar et al 1990;Walter et al 2004;D'Annibale et al 2005;Tortella et al 2005;Papinutti et al 2006;Rubilar et al 2008;Tortella et al 2008). The ability of fungi to degrade pollutants has been attributed to the action of an extracellular and non specific ligninolytic enzyme system, composed of laccase, lignin peroxidase (LiP) and manganese peroxidase (MnP) (Heinzkill et al 1998).…”

“…Also, they provide resistance to competition by indigenous microbes (Lestan and Lamar 1996;Walter et al 2004;Rubilar et al 2007). The lignocellulosic materials have lignin that prevents the microorganisms proliferation, as this molecule can not be used as the sole carbon and energy source.…”

“…These materials can stimulate ligninolytic enzyme production, fungus growth and consequently pollutant degradation (Lestan and Lamar 1996;Walter et al 2004), being the organic supports most commonly used: ear corn, sawdust, wood chips, sugarcane bagasse and wheat straw (Moredo et al 2003;Dzul-Puc et al 2005;Mohammadi and Nasernejad 2009;Lu et al 2009). …”
