“…The phylum-level phylogenetic fingerprint of fungal communities in this study produced a total of 6 phyla dominated by Ascomycota whose relative abundance ranged from 23.29% in Dixon to 38.31% in Ford samples, followed by Basidiomycota with a relative abundance of 17.34% in Capegate to 33.51% in Chemreem effluents. Similar to the present findings, previous studies on fungal diversity in industrial wastewater treatment plants using clone libraries found fungal communities to be dominated by fungi of the phyla Ascomycota and Basidiomycota [16,20,31]. The overwhelming abundance of fungi belonging to these two phyla may be attributed to the fact that Ascomycota constitutes the largest phylum of fungi encompassing more than 33,000 named species Fig.…”

The actual extent of fungal diversity in different environmental media is still a subject of ongoing research. Little is currently known about the diversity of fungal populations in industrial streams. This study characterized the fungal diversity of different industrial effluents using a high-throughput sequencing approach. A total of 234617 quality filtered reads were obtained from the collected wastewater samples. Phylogenetic taxonomy revealed that resident fungal communities were classified as 6 phyla, 31 classes, 79 orders, 144 families, and 192 genera. Ascomycota and Basidiomycota were the most dominant phyla whose relative abundance ranged from 23.29% to 38.31%, and 17.34% to 33.51%, respectively. Recovered operational taxonomic units (OTUs) ranged from 292 (Dixon) to 427 (Capegate). The existence of some fungal genera identified in the industrial wastewaters correlated to physicochemical variables and had the potential to play important roles in organic decomposition, pollutant degradation, and xenobiotic transformation. Meanwhile, the occurrence of unclassified fungal sequences (22.5% to 33.09%) suggests that these effluents are a potential reservoir of as-yet uncharacterized fungal species.

“…Dishwashers and carwashes have been categorized as some of the man‐made extreme environments housing extremophilic fungi (Zalar, Novak, De Hoog, & Gunde‐Cimerman, ). Further, the discharge of pollutants into the environment contributes to environmental toxicity (Spina, Anastasi, Prigione, Tigini, & Varese, ), and induces physiological and morphological changes in indigenous microbial flora (Tahir, ). This exerts a selective pressure that favors the growth and proliferation of those microorganisms that are able to tolerate and use introduced pollutants to their advantage.…”

Urban life has created man‐made extreme environments like carwashes. These environments have, however, not been sufficiently explored for mycobiota that can be sources of biotechnologically useful products, as has been the case with natural extreme environments. Using a combination of culture and molecular techniques, fungi from carwash effluents was characterized for production of lipase and cellulase enzymes, nonpolar and polar biotechnologically relevant secondary metabolites and hydrocarbon utilization. The isolated fungal strains belonged to the genera Alternaria, Cladosporium, Penicillium, Peyronellaea, Rhizopus, Spegazzinia, Trichoderma, Ulocladium and Yarrowia. Sixty‐six percent (66%) of the fungal isolates were found to be able to metabolize naphthalene and benzanthracene, showing potential for application in bioremediation of hydrocarbon polluted sites. Lipase production by the isolates Penicillium sp. BPS3 (2.61 U/ml), Trichoderma sp. BPS9 (2.01 U/ml), Rhizopus sp. CAL1 (2.05 U/ml), Penicillium sp. PCW1 (2.99 U/ml) and Penicillium sp. SAS1 (2.16 U/ml) compared well with previously recorded lipase production levels by other fungi. The highest producers of cellulase were Penicillium sp. SAS1 (12.10 U/ml), Peyronella sp. CAW5 (4.49 U/ml) and Cladosporium sp. SAS3 (4.07 U/ml), although these activities were lower than previously reported levels. GC‐MS analysis of the fungal secondary metabolites resulted in identification of 572 compounds, including azulene, methanamine, N‐pentylidene, metoclopramide, and mepivacaine while compounds determined by UHPLC‐MS included 10‐undecen‐1‐ol, piquerol A, 10‐undecyn‐1‐ol, cyclo(leucylprolyl) and rac‐etomidate. These compounds were previously determined to have various activities including anticancer, antibacterial, antifungal, antihypertensive, antidiabetic and anti‐inflammatory properties. The study demonstrated that fungi from carwash effluents are natural sources of some biotechnologically important products.

“…Aspergillus has been reported to have higher accumulation capacity than Penicillium for many metals such as cobalt, chromium, copper, cadmium, and nickel [ 49 ], and A. niger has been reported to have especially high accumulation capacity [ 50 ]. Meanwhile, Mucor was reported to lower the capacity for accumulation of some metals like copper [ 51 ]. The difference in GNP toxicity sensitivities may be caused by higher accumulation of GNPs by A. niger , while P. chrysogenum and M. hiemalis accumulated fewer.…”

Gold nanoparticles (GNPs) are increasingly being used in a wide range of applications, and such they are being released in greater quantities into the environment. Consequently, the environmental effects of GNPs, especially toxicities to living organisms, have drawn great attention. However, their toxicological characteristics still remain unclear. Fungi, as the decomposers of the ecosystem, interact directly with the environment and critically control the overall health of the biosphere. Thus, their sensitivity to GNP toxicity is particularly important. The aim of this study was to evaluate the role of GNP shape and size in their toxicities to fungi, which could help reveal the ecotoxicity of GNPs. Aspergillus niger, Mucor hiemalis, and Penicillium chrysogenum were chosen for toxicity assessment, and spherical and star/flower-shaped GNPs ranging in size from 0.7 nm to large aggregates of 400 nm were synthesised. After exposure to GNPs and their corresponding reaction agents and incubation for 48 h, the survival rates of each kind of fungus were calculated and compared. The results indicated that fungal species was the major determinant of the variation of survival rates, whereby A. niger was the most sensitive and M. himalis was the least sensitive to GNP exposure. Additionally, larger and non-spherical GNPs had relatively stronger toxicities.
