Bioremediation of soil: an overview
(Elsevier, 2022) Mehjabeen; Anoop Kumar Devedee; Monalisa Sahoo; Kartikeya Choudhary; Mahendra Singh; Ghanshyam
Soil pollution is a major and growing concern all over the globe and a serious threat to the environment as well as to living organisms. Different pollutants, viz. heavy metals, radionuclides, organic pollutants, plastics, agrochemicals like pesticides, herbicides, etc. are known to pollute the soil and reduce the already limited arable land important for food production. In search of economical and eco-friendly remediation techniques many methodologies have been devised, such as rhizoremediation and phytoremediation, and by using them polluted lands can be put back in cultivation or other types of production systems without harming the environment any further. Bioremediation is one such technique in which microorganisms are employed for the purpose directly or indirectly. Bioremediation means the use of biological agents to detoxify and degrade environmental contaminants. Using microorganisms for remediation reduces time and labor by a variety of mechanisms. They help in bioremediation via various mechanisms such as biosorption, EPS production, metalloproteins, metal resistant genes, SOD, POD, Catalase production, volatilization, and siderophore production. Some of the microbial strains used for bioremediation are Pseudomonas, Rhizobium, Klebsiella, Bacillus, Enterobacter, and others. Microbial inoculation decreases the MDA (malondialdehyde) and H2O2 content by 20% and 33%, respectively. They also increase the antioxidant enzymes such as SOD (superoxide dismutase enzyme) and catalase by 30% and 7%, respectively. They can also biotransform the oxidation states of toxic metals to nontoxic ones. They even enhance the hyperaccumulator capacity to aid phytoremediation. © 2022 Elsevier Inc. All rights reserved.
Soil Bioremediation Approaches Based on the Use of Fungal Enzymes
(Springer International Publishing, 2022) Anoop Kumar Devedee; Monalisa Sahoo; Mehjabeen; Kartikeya Choudhary; R.K. Singh
The heightened increase in pollutants in the environment including soil due to the addition of different toxic chemical compounds resulting from geogenic and various anthropogenic activities is a worldwide concern. There have been a number of evidences regarding involvement of bacterial enzymes in soil bioremedi-ation of these toxic pollutants but little work has been accomplished regarding poten-tial fungal enzymes. In this context, development of bioremediation techniques with filamentous fungi and their oxidative enzymatic activities could be of great potent to reduce toxicity of soil pollutants namely polyaromatic hydrocarbons (PAHs), halogenated compounds, polyphenols, heavy metals, etc. Although, bioremediation through enzymatic activities of fungi is a cost-effective and eco-friendly technology, and many studies have already been performed using fungal cultures, but its study has been restricted. Therefore, more work needs to be done in this field for a commer-cial breakthrough regarding the use of fungal enzymes in soil bioremediation. A variety of lignolytic and filamentous fungi have been studied to perform the function employing their capability to transform or degrade specific contaminants using their enzymatic activities. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2022.
