“…The quest for substitutes to the well-known conventional technologies for the elimination of Cr (VI) paves the way for the utilization of fungi, bacteria and yeast as bio-sorption and bioremediation agents. Comparatively, this biological system is cheaper, more effective and more ecofriendly than the conventional clean-up techniques (Carol et al, 2012;Igiehon, 2015). These biological agents can be used to clean-up sites contaminated with industrial effluents, hydrocarbon polluted sites and even agricultural land deteriorated by heavy metals since according to Ndeddy Aka and Babalola (2017) metal such as chromium, cadmium and nickel are the main pollutants that compromise soil quality, plant production as well as human health globally.…”

Soil and water pollution caused by heavy metals can result in health challenges such as cancer. Therefore, this study was aimed at testing the ability of Aspergillus fumigatus and Rhizopus sp. isolated from cassava grinding mill environment to reduce, bio-accumulate and tolerate Cr (VI) in Norkran’s medium. Fungal isolates were obtained from soil samples using 2 % malt extract agar. Cr (VI) reduction potential of the fungal cells was done using shake flask method. The tolerance of fungal isolates to the different concentrations of Cr (VI) used for the bio-sorption experiment was determined by collecting 1 ml of Norkran’s sample from each experimental flask on days 0, 5, 10 and 20 followed by inoculation in 2 % malt extract agar plates. The ability of fungal isolates to adapt to increasing Cr (VI) concentrations was ascertained by inoculating mycelial ball on 2 % malt extract agar amended with 16.1 mg/L of Cr (VI). There were reductions of Cr (VI) for all the treatments amended with A. fumigatus and Rhizopus sp. at 16.1, 8.1, 4.0 and 2.0 mg/L concentrations of Cr (VI) while 50 % decrease in Cr (VI) concentrations was observed for treatments inoculated with Rhizopus sp. on days 20, 10 and 5 at concentrations of 8.1, 4.0 and 2.0 mg/L respectively. The amounts of Cr (VI) observed at a concentration of 16.1 mg/L on day 20 for treatments inoculated with Rhizopus sp. were observed to be significantly less than (P<0.05) those of A. fumigatus. The fungal tolerance assay demonstrated increase in fungal abundance throughout the experimental period for all the treatments indicating that the different concentrations of Cr (VI) used were not toxic to the fungal species. Induce-tolerance assay suggested that Cr (VI) was able to induce metal tolerance potential in these fungal species. Findings from this investigation revealed that these fungi can be further explored biotechnologically to clean-up chromium contaminated environment

Microorganisms are immense in nature and exist in every imaginable ecological niche, performing a wide range of metabolic processes. Unfortunately, using traditional microbiological methods, most microorganisms remain unculturable. The emergence of metagenomics has resolved the challenge of capturing the entire microbial community in an environmental sample by enabling the analysis of whole genomes without requiring culturing. Metagenomics as a non-culture approach encompasses a greater amount of genetic information than traditional approaches. The plant root-associated microbial community is essential for plant growth and development, hence the interactions between microorganisms, soil, and plants is essential to understand and improve crop yields in rural and urban agriculture. Although some of these microorganisms are currently unculturable in the laboratory, metagenomic techniques may nevertheless be used to identify the microorganisms and their functional traits. A detailed understanding of these organisms and their interactions should facilitate an improvement of plant growth and sustainable crop production in soil and soilless agriculture. Therefore, the objective of this review is to provide insights into metagenomic techniques to study plant root-associated microbiota and microbial ecology. In addition, the different DNA-based techniques and their role in elaborating plant microbiomes are discussed. As an understanding of these microorganisms and their biotechnological potentials are unlocked through metagenomics, they can be used to develop new, useful and unique bio-fertilizers and bio-pesticides that are not harmful to the environment.
