“…Exophiala xenobiotica was found to be dominant black yeast present in the car gasoline tanks, able to use toluene as a carbon source (Isola et al, 2013). Fusarium solani was reported to tolerate caffeine concentration of 8 g/L (Nayak et al, 2013). It is reported that Trametes versicolor (3000 UL −1 ) could produce laccase and Pleurotus ostreatus (2700 UL −1 ) showed the ability to degrade PAHs, phenanthrene (PHE) and pyrene (PYR) (Rosales et al, 2013).…”

In this study, we report the presence of a microbial community of bioremediation potential in terms of relative abundance and taxonomic biodiversity in sediment samples of river Ganga and Yamuna, India at nine different sites. Metagenomic libraries were constructed using TruSeq Nano DNA Library Prep Kit and sequenced on NextSeq 500 by Illumina Next Generation Sequencing (NGS) technology. Bioremediation bacteria belong to 45 genera with 92 species and fungi belong to 13 genera with 24 species have been classified using Kaiju taxonomical classification. The study revealed that Proteobacteria was the most dominant bacterial flora, followed by Actinobacteria, Firmicutes, and Deinococcus-Thermus. PCA analysis revealed that bioremediation bacteria viz. Streptomyces bikiniensis, Rhodococcus qingshengii, Bacillus aerophilus, Pseudomonas veronii, etc., were more dominant in highly polluted river stretch as compared to less polluted river stretch. Similarly, the relative abundance of bioremediation fungi viz. Phanerochaete chrysosporium and Rhizopus oryzae, etc., were significantly correlated with the polluted Kanpur stretch of river Ganga. Several protein domains, which play a pivotal role in bioremediation in the polluted environments, including urea ABC transporter, UrtA, UrtD, UrtE, zinc/cadmium/mercury/lead-transporting ATPase, etc., were identified using protein domain analysis. The protein domains involved in pesticide biodegradation viz. P450, short-chain dehydrogenases/reductases (SDR), etc., were also discovered in river sediment metagenomics data. This is the first report on the richness of bioremediation microbial communities in the Ganga and Yamuna riverine ecosystems, highlighting their importance in aquatic pollution management.

“…Bioremediation/decolourization of coloured effluents from sugar industry, textile dye, bleached kraft pulp mill, leather tanning effluents has been reported in case of fungi belonging to various groups including Aspergillus, Penicillium and alkalophilic white-rot fungi indicating diverse substrate preference of these fungi [14,[60][61][62][63][64]. Coffee pulp could be decaffeinated in presence of fungi under controlled conditions with extra nutrients for applications in animal feed preparation or for bioethanol production as was studied in case of fungi such as Aspergillus restrictus, Chrysosporium keratinophilum, Fusarium solani, Gliocladium roseum, Penicillium and Stemphylium [65]. Bioremediation in presence of fungi A. niger and P. chrysosporium exhibited substantial removal of petroleum hydrocarbons from soil contaminated with petrol and diesel at short incubation periods as indicated by enhanced total organic carbon (TOC) removal [66].…”

Diverse Metabolic Capacities of Fungi for Bioremediation

Bioremediation refers to cost-effective and environment-friendly method for converting the toxic, recalcitrant pollutants into environmentally benign products through the action of various biological treatments. Fungi play a major role in bioremediation owing to their robust morphology and diverse metabolic capacity. The review focuses on different fungal groups from a variety of habitats with their role in bioremediation of different toxic and recalcitrant compounds; persistent organic pollutants, textile dyes, effluents from textile, bleached kraft pulp, leather tanning industries, petroleum, polyaromatic hydrocarbons, pharmaceuticals and personal care products, and pesticides. Bioremediation of toxic organics by fungi is the most sustainable and green route for cleanup of contaminated sites and we discuss the multiple modes employed by fungi for detoxification of different toxic and recalcitrant compounds including prominent fungal enzymes viz., catalases, laccases, peroxidases and cyrochrome P450 monooxygeneses. We have also discussed the recent advances in enzyme engineering and genomics and research being carried out to trace the less understood bioremediation pathways.

“…The G. roseum strain has a maximum degradation of about 1.5 mg/ml at 72 h in a medium with the presence of nitrogen. C. keratinophilum has the highest rates of degradation without the presence of nitrogen (0.5 mg/ml) at 72 h. In another evaluation it was reported that nitroten in the medium, but not glucose, affects caffeine degradation (Nayak et al, 2013;Pai et al, 2013).…”
