Industrial Effluents Harbor a Unique Diversity of Fungal Community Structures as Revealed by High-throughput Sequencing Analysis

Abstract

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.

Chromium (VI) bioremediation potential of filamentous fungi isolated from Peruvian tannery industry effluents

“…(P3-01), and Trichoderma viride (P1-01). Several studies [16][17][18] show that filamentous fungi from the phylum Ascomycota are common in mycoflora in industrial effluents. The growth capacity of fungal strains at different chromium (VI) concentrations was evaluated in solid medium ( Fig.…”

Diversity, Co-occurrence and Implications of Fungal Communities in Wastewater Treatment Plants

“…All PCR products were sequenced using the Illumina Mi-Seq platform at Inqaba Biotechnology (Pretoria, South Africa). Mothur (V 1.39.5) pipeline was used to Analyse the raw sequence data following previous methods 74,75 . Briefly, reads with more than 1% ambiguities or 8% of homopolymers were excluded from processing after merging the paired-end reads into contigs .…”

Seasonal fluctuations and diversity of Ingoldian mycobiota in two water bodies receiving different effluents at Assiut Governorate (Upper Egypt)

“…Our results support and corroborate the findings of Pietryczuk et al [ 19 ] who revealed that water pollution usually leads to a decrease in the taxonomic diversity of aquatic hyphomycetes, including the complete disappearance of some species such as Tetracladium breve or Tricladium sp. Similarly, Selvarajan et al [ 48 ] reported lower fungal diversity and species richness in highly contaminated environments.
