“…Perhaps during the degradation of these substrates, fungus produces substances with emulsifying activity that can make them more accessible. In some cases, the presence of emulsifying activity is associated with the production of EPS, or with "nonpolysaccharide" fungal products, such as glycoproteins [81].…”

The ability of sixteen wood- and soil-inhabiting basidiomycete strains and four ascomycete strains to degrade the most hazardous, widespread, and persistent pollutants (polycyclic aromatic hydrocarbons, oxyethylated nonylphenol, alkylphenol, anthraquinone-type synthetic dyes, and oil) was found. The disappearance of the pollutants, their main metabolites, and some adaptive properties (activities of ligninolytic enzymes, the production of emulsifying compounds and exopolysaccharides) were evaluated. The toxicity of polycyclic aromatic hydrocarbons decreased during degradation. New data were obtained regarding (1) the dependence of the completeness of polycyclic aromatic hydrocarbon degradation on the composition of the ligninolytic enzyme complex; (2) the degradation of neonol AF9-12 by higher fungi (different accessibilities of the oxyethyl chain and the aromatic ring of the molecules to different fungal genera); and (3) the production of an emulsifying agent in response to the presence in the cultivation medium of hydrophobic pollutants as the common property of wood- and soil-inhabiting basidiomycetes and ascomycetes. Promise for use in mycoremediation was shown in the wood-inhabiting basidiomycetes Pleurotus ostreatus f. Florida, Schizophyllum commune, Trametes versicolor MUT 3403, and Trametes versicolor DSM11372; the litter-decomposing basidiomycete Stropharia rugosoannulata; and the ascomycete Cladosporium herbarum. These fungi degrade a wide range of pollutants without accumulation of toxic metabolites and produce ligninolytic enzymes and emulsifying compounds.

“…In a study carried out by on bioremediation by Fusarium solani along with a chemical and combined method, it was found that the combined method gave only 25% degradation of benzo(a)pyrene. [42][43][44] A combined Fenton-microbial study by Palmroth et al (2006) 22 on remediation of PAHs from creosote oil-contaminated soil could achieve 43-59% conversion while incubation alone gave only 22-30% degradation. The present work, however, tested the degradation of only the aliphatic hydrocarbons in crude oil and therefore, 75% degradation was not surprising, but a remarkable result.…”

The study is aimed at the remediation of soil spiked with crude oil (5%) by employing Fenton oxidation, biological treatment and combined Fenton-biological treatment. A spiked concentration of 5% crude oil was selected on the basis of contamination levels of 0-5% as found in the soil of upper Assam oil fields (India). The degradation of the aliphatic fraction (C14-C28) of the crude oil was investigated by gas chromatography. Fenton oxidation was carried out at different pH (3 to 8) in a laboratory batch reactor and maximum oxidative degradation was observed at pH 3-5. At pH 3, single Fenton oxidation resulted in 36 and 57% degradation in 5 and 10 days respectively. Biological treatment (with Fusarium solani) and combined Fenton-biological treatment were carried out with a one month incubation period. Biological treatment alone brought about 61% degradation of the crude oil while the combined process could achieve as much as 75% degradation of the aliphatic fractions of the crude oil.

Polycyclic aromatic hydrocarbons (PAHs) and volatile organic compounds (VOCs) are important indoor contaminants. Their hydrophobic nature hinders the possibility of biological abatement using biofiltration. Our aim was to establish whether the use of a consortium of Fusarium solani and Rhodococcus erythropolis shows an improved performance (in terms of mineralization rate and extent) towards the degradation of formaldehyde, as a slightly polar VOC; toluene, as hydrophobic VOC; and benzo[α]pyrene (BaP) as PAH at low concentrations compared to a single-species biofilm in serum bottles with vermiculite as solid support to mimic a biofilter and to relate the possible improvements with the surface hydrophobicity and partition coefficient of the biomass at three different temperatures. Results showed that the hydrophobicity of the surface of the biofilms was affected by the hydrophobicity of the carbon source in F. solani but it did not change in R. erythropolis. Similarly, the partition coefficients of toluene and BaP in F. solani biomass (both as pure culture and consortium) show a reduction of up to 38 times compared to its value in water, whereas this reduction was only 1.5 times in presence of R. erythropolis. Despite that increments in the accumulated CO and its production rate were found when F. solani or the consortium was used, the mineralization extent of toluene was below 25%. Regarding BaP degradation, the higher CO production rates and percent yields were obtained when a consortium of F. solani and R. erythropolis was used, despite a pure culture of R. erythropolis exhibits poor mineralization of BaP.
