“…Aspergillus niger had the highest frequency of occurrence than others in the present study as also reported by Oshoma et al (2017) and Bala et al (2020), and this might be due to its unique characteristics. Apart from being ubiquitous in nature, A. niger also has extensive metabolic diversity, including its non-fastidious nutritional requirements (Bakare et al, 2019;Zhao et al, 2020).…”

A large number of microorganisms are capable of degrading cellulose but only a few of these microorganisms produce significant quantities of enzymes capable of completely hydrolyzing cellulose. Fungi are the main cellulase-producing microorganisms. This study was aimed to determine the cellulolytic potentials of Aspergillus species isolated from the central waste dump site of Nile University of Nigeria. In this study, fungal species were isolated from soil samples obtained from waste dump site using pour plate technique. The isolates were characterized using cultural and morphological features as well as microscopic examination. Aspergillus flavus, Aspergillus niger, and Aspergillus terreus, which were isolated were further screened on carboxymethylcellulose agar for their ability to degrade cellulose. Screening of fungal isolates was performed by plate method. Cellulolytic fungi were evaluated after 5 days for the production of cellulolytic enzymes by staining with 1% Congo red. The diameter of clear zone on fungal plates, gave an approximate indication of cellulase activities. Aspergillus niger had a zone of clearing of 25.50 mm while Aspergillus flavus had 18.50 mm. Aspergillus terreus did not show any cellulolytic activity. Aspergillus niger had the highest occurrence rate of 50%. Aspergillus flavus and Aspergillus terreus both had 25% occurrence rate.

“…Serial dilution was done up to 10ˉ3 dilutions. One gram of the soil sample was placed into a sterilized test tube containing 9 mL of pure distilled water to give a 10-fold (1:10) dilution (Bala et al, 2020). Potato dextrose agar (PDA) (HiMedia, Mumbai, India) was poured into a Petri dish containing 1 mL of the desired aliquot.…”

A lead (Pb) smelter plant located in Owino Uhuru, a suburb of Mombasa County, caused lead poisoning and lifelong health effects. The Government of Kenya closed down the plant after reports of contamination. This study collected 24 soil samples from Owino Uhuru and analyzed them for lead levels using Microplasma Atomic Emission Spectrometry. The study also isolated and identified seven strains of fungi from the lead-contaminated soil and screened them for their ability to absorb lead. The genomic DNA of the fungal isolates was identified using ITS sequences of the rDNA. Blastn analysis indicated that the ITS gene sequences of the isolates had similarities of > 100% with known sequences in the nucleotide sequence database. These fungi were identified as Aspergillus welwitschiae, Aspergillus oryzae, Aspergillus piperis, Aspergillus austwickii, Aspergillus aflatoxiformans and Aspergillus tubingensis. The fungal isolates were tested for their ability to absorb lead at concentrations of 1.0 ppm, 0.8 ppm, 0.6 ppm, 0.4 ppm, and 0.2 ppm. The soil sample closest to the battery recycling plant contained more lead than those collected further away. Soil sample AU06, taken from the area bordering the wall of the lead smelter plant, had the highest lead concentration compared to all the samples. Aspergillus welwitschiae (GRY1) showed a higher potential for lead biosorption of 0.35 ± 0.1 ppm at 0.6 ppm lead concentration compared to other Aspergillus species. The study suggests using these fungal isolates for the removal and bio-treatment of lead-contaminated and polluted environments.

“…In comparison to A. niger; P. chrysogenum was found to show higher biosorption potential or lead removal. In this way their study may be useful in the heavy metal bioremediation using these isolated fungi (Bala et al, 2020). was on the basis of morphological characteristics and the sequencing of their ITS-rDNA region.…”

“…Microbial processes described by them for the bioremediation of heavy metal toxicity may be useful in their removal study (Rahman & Singh, 2020). Bala et al (2020) studied on the lead tolerant fungi that were isolated from refuse dumpsite soil and identified as Aspergillus niger , Penicillium chrysogenum , and Rhizomucor sp. The isolates have been screened for metals like zinc, lead, and cadmium with concentration 600 ppm, 400 ppm, and 200 ppm.…”

In the present time of speedy developments and industrialization, heavy metals are being uncovered in aquatic environment and soil via refining, electroplating, processing, mining, metallurgical activities, dyeing and other several metallic and metal based industrial and synthetic activities. Heavy metals like lead (Pb), mercury (Hg), cadmium (Cd), arsenic (As), Zinc (Zn), Cobalt (Co), Iron (Fe), and many other are considered as seriously noxious and toxic for the aquatic environment, human, and other aquatic lives and have damaging influences. Such heavy metals, which are very tough to be degraded, can be managed by reducing their potential through various processes like removal, precipitation, oxidation–reduction, bio‐sorption, recovery, bioaccumulation, bio‐mineralization etc. Microbes are known as talented bio‐agents for the heavy metals detoxification process and fungi are one of the cherished bio‐sources that show noteworthy aptitude of heavy metal sorption and metal tolerance. Thus, the main objective of the authors was to come with a comprehensive review having methodological insights on the novel and recent results in the field of mycoremediation of heavy metals. This review significantly assesses the potential talent of fungi in heavy metal detoxification and thus, in environmental restoration. Many reported works, methodologies and mechanistic sights have been evaluated to explore the fungal‐assisted heavy metal remediation. Herein, a compact and effectual discussion on the recent mycoremediation studies of organic pollutants like dyes, petroleum, pesticides, insecticides, herbicides, and pharmaceutical wastes have also been presented.
