Moreover, comparing the quantitative results of this study with the findings of Muzikář and colleagues () makes it possible to state that CBAs are degraded by P. ostreatus even more rapidly than PCBs. This is of high importance because Svobodová and colleagues () documented that CBAs possessed oestrogenic activity, in contrast to the technical mixture of PCBs, which was mostly androgenic.…”

“…A certain concern could rise from the detection of CBAs as metabolites that probably play an important role in the persistency of PCBs toward bacterial biodegradation. However, in a work by Muzikář and colleagues (), transformation of 12 representatives of CBAs under liquid conditions was described in detail, showing that the compounds were efficiently degraded by eight LF strains where I. lacteus and P. ostreatus appeared to be the most efficient in degradation and toxicity removal. A number of metabolites were identified and the findings confirmed the reductive pathway of CBAs as a possible transformation route (Fig.…”

SummaryWithout any doubt, endocrine-disrupting compounds (EDCs) represent an environmental risk for wildlife and human beings. Endocrine-disrupting effects were found for many chemicals in products for personal use, industrial compounds and even in classical persistent organic pollutants (POPs). In order to understand the fate of EDCs in the environment, it is highly important to identify and to clarify the biodegradation mechanisms that can lead to their decomposition. Ligninolytic fungi (LF) are interesting microorganisms that are capable of participating in a variety of versatile decomposition mechanisms. The microorganisms represent a useful model group and, moreover, LF or their enzymes can be actively used for decontamination. Potential optimization of the decontamination process provides another important reason why it is necessary for understanding the mechanisms of EDC transformation. This minireview summarizes current knowledge about the LF biodegradation mechanisms of the most important micropollutants (xenoestrogens), including nonylphenols, bisphenol A and 17α-ethinylestradiol and polychlorinated biphenyls as POPs with endocrine-disrupting potency. Generally, LF exhibit the ability to either polymerize the target pollutants or to substantially decompose the original structure using ligninolytic enzymes and cytochrome P-450. Moreover, most of the transformation processes are accompanied by reduction of the endocrine-disrupting activity or ecotoxicity.

Degradation of chlorobenzoic acids (e.g., products of microbial degradation of PCB) by strains of microorganisms isolated from PCB contaminated soils was assessed. From seven bulk-soil isolates two strains unique in ability to degrade a wider range of chlorobenzoic acids than others were selected, individually and even in a complex mixture of 11 different chlorobenzoic acids. Such a feature is lacking in most tested degraders. To investigate the influence of vegetation on chlorobenzoic acids degraders, root exudates of two plant species known for supporting PCB degradation in soil were tested. While with individual chlorobenzoic acids the presence of plant exudates leads to a decrease of degradation yield, in case of a mixture of chlorobenzoic acids either a change in bacterial degradation specificity, associated with 3- and 4-chlorobenzoic acid, or an extension of the spectrum of degraded chlorobenzoic acids was observed.

“…D. squalens is a promising reference species for studying wood degradation by white-rot fungi and in addition it also has a potential for biotechnology applications, such as in bioremediation of environmental pollutants (Muzikář et al, 2011). The recent establishment of a transformation system (Daly et al, 2017) facilitates genetic modification to study the underlying molecular mechanisms of wood decay.…”

Summary White‐rot fungi, such as Dichomitus squalens, degrade all wood components and inhabit mixed‐wood forests containing both soft‐ and hardwood species. In this study, we evaluated how D. squalens responded to the compositional differences in softwood [guaiacyl (G) lignin and higher mannan content] and hardwood [syringyl/guaiacyl (S/G) lignin and higher xylan content] using semi‐natural solid cultures. Spruce (softwood) and birch (hardwood) sticks were degraded by D. squalens as measured by oxidation of the lignins using 2D‐NMR. The fungal response as measured by transcriptomics, proteomics and enzyme activities showed a partial tailoring to wood composition. Mannanolytic transcripts and proteins were more abundant in spruce cultures, while a proportionally higher xylanolytic activity was detected in birch cultures. Both wood types induced manganese peroxidases to a much higher level than laccases, but higher transcript and protein levels of the manganese peroxidases were observed on the G‐lignin rich spruce. Overall, the molecular responses demonstrated a stronger adaptation to the spruce rather than birch composition, possibly because D. squalens is mainly found degrading softwoods in nature, which supports the ability of the solid wood cultures to reflect the natural environment.
