Five fungal strains that are able to grow on toluene were isolated from enrichment cultures. Three different techniques were used: solid state-like batches, air biofilters and liquid cultures. Fungal growth in the latter systems was favoured by combining low pH and low water activity. Soil and groundwater samples from gasoline-polluted environments were used as inocula. The isolates were identified as deuteromycetes belonging to the genera Cladophialophora, Exophiala and Leptodontium and the… Expand
Growth of fungi on volatile aromatic hydrocarbons: environmental technology perspectives
The present study aimed the better understanding of the catabolism of monoaromatic hydrocarbons by fungi. This knowledge can be used to enhance the biodegradation of BTEX pollutants. Fungi with theExpand
Black Fungi and Hydrocarbons: An Environmental Survey for Alkylbenzene Assimilation
TLDR
Nineteen strains were selected as the most promising for further investigation on the biodegradation of alkylbenzenes, and they were screened for their toluene assimilation potential using a simple and inexpensive methodology based on miniaturized incubations under controlled atmospheres. Expand
Biosystematics and ecology of hydrocarbon-degrading fungi from air biofilters
TLDR
Additional studies on the potential biohazard of fungal biofiltration of aromatic hydrocarbons are strongly recommended prior to the full-scale implementation of this technique. Expand
Isolation and Screening of Black Fungi as Degraders of Volatile Aromatic Hydrocarbons
TLDR
Black fungi reported as degraders of volatile aromatic compounds were isolated from hydrocarbon-polluted sites and indoor environments, finding Exophiala xenobiotica was found to be the dominant black yeast present in the car gasoline tanks and a higher biodiversity, with three Exophia species, was found in soap dispensers of washing machines.

Pathogenic Yet Environmentally Friendly? Black Fungal Candidates for Bioremediation of Pollutants
TLDR
The outstanding abilities of black yeast-like fungi to thrive in extreme environments makes them ideal agents for the bioremediation of polluted soils, and for the treatment of contaminated gas streams in biofilters. Expand
Isolation and Identification of Black Yeasts by Enrichment on Atmospheres of Monoaromatic Hydrocarbons
TLDR
A selective technique to promote the in vitro growth of herpotrichiellaceous fungi was applied to investigate their ecophysiology and found the majority of the obtained isolates were affiliated to the recently described species Exophiala xenobiotica and Exophia bergeri. Expand
Diversity of culturable fungi inhabiting petroleum-contaminated soils in Southern Iran
TLDR
The crude oil substrate was the most successful isolation method, and among the four hydrocarbon enrichments, toluene substrate yielded the highest number of strains. Expand
Fungi growing on aromatic hydrocarbons: biotechnology's unexpected encounter with biohazard?
TLDR
There may be physiological connections between hydrocarbon assimilation and certain patterns of mammalian infection, based in part on re-evaluation of a collection of published hydrocarbon-degrading isolates obtained from authors around the world. Expand
Bioremediation of BTEX Hydrocarbons: Effect of Soil Inoculation with the Toluene-Growing Fungus Cladophialophora Sp. Strain T1
TLDR
The biodegradation of a mixture of benzene, toluene, ethylbenzene, xylene, (BTEX) and methyl-tert-butyl ether (MTBE) was studied in soil microcosms and indicated that no severe antagonism occurred between the indigenous bacteria and Cladophialophora sp. Expand
Diversity of opportunistic black fungi on babassu coconut shells, a rich source of esters and hydrocarbons.
TLDR
Assimilation of alkylbenzenes by the black yeasts might be the result of evolutionary adaptation to symbiotic interactions with higher plants and the potential relationship between lipid/aromatic hydrocarbon metabolism and pathogenicity is discussed. Expand

Kinetics of competitive inhibition and cometabolism in the biodegradation of benzene, toluene, and p‐xylene by two Pseudomonas isolates.
TLDR
Two Pseudomonas species were isolated from an aerobic pilot‐scale fluidized bed reactor treating groundwater containing benzene, toluene, and p‐xylene, and batch tests using paired substrates revealed competitive inhibition and cometabolic degradation patterns. Expand
Degradation of Toluene and Trichloroethylene by Burkholderia cepacia G4 in Growth-Limited Fed-Batch Culture
TLDR
Although strain G4 is much less sensitive to TCE toxicity than methanotrophs, deleterious effects may still occur, namely, an increased maintenance energy demand in the presence of toluene and plasmid loss when no toLUene is added. Expand
Effect of Trichloroethylene on the Competitive Behavior of Toluene-Degrading Bacteria
TLDR
The results indicate that cometabolic degradation of TCE has a negative effect on the maintenance and competitive behavior of toluene-utilizing organisms that transform TCE. Expand

Growth of the fungus Cladosporium sphaerospermum with toluene as the sole carbon and energy source
TLDR
The oxygen consumption rates, as well as the measured enzyme activities, of toLUene-grown C. sphaerospermum indicate that toluene is degraded by an initial attack on the methyl group. Expand
Toluene degradation kinetics for planktonic and biofilm-grown cells of Pseudomonas putida 54G.
TLDR
The results suggest that long-term toluene exposure caused a large portion of the biomass to become inactive, even though the biofilm was not substrate limited, and changes in cellular activity that occur during biofilm development should be investigated under conditions relevant to reactor operation.

Extracellular lipids of Cladosporium (Amorphotheca) resinae grown on glucose or on n-alkanes.
TLDR
Cladosporium (Amorphotheca) resinae was grown in shake culture on glucose, n-dodecane, or n-hexadecane, and dodecanoic acid was the predominant fatty acid (greater than 60%) in neutral lipids from all three media, with lesser amounts of tetradecanoic, hexadecanic, and octadecanoIC acids. Expand

TLDR
Diverse microorganisms using diverse metabolic pathways have the capacities for degrading a wide spectrum of hydrocarbon structures in petroleum, some pathways lead to detoxification and destruction of the pollutants whereas others activate potentially harmful compounds. Expand

TLDR
A general mathematical model developed for a description of pollutant degradation in a biofilm was used to evaluate the performance of a biofilter for the purification of styrene-containing gas and indicated an effective biofilm thickness of about 80 microm. Expand
