A reappraisal on biodegradation of fluoride compounds: role of microbes

Abstract

Fluorine is a highly reactive gas, rarely occurs in nature, in elemental form. Fluorosis is an excruciating and crippling disease caused by fluoride intake. Microbial degradation is cost‐effective and eco‐friendly method of removing fluoride compounds. The enzymes and genes involved in the fluoride‐degrading pathway have been identified and characterised. The in‐silico studies on degradative enzymes and their molecular interaction can be more advantageous in understanding fluoride toxicity and its degradative efficiency. Microbes exhibiting fluoride degradative potential or fluoride adsorption potential can be used for bioremediation of fluoride‐contaminated water. Large population is affected by fluorosis; both the welfare state and researchers are required to address the problem. The microbial degradation of fluoride provides sustainable, cost‐effective and ecofriendly technology. In the present review, an attempt has been made to compile all the available literature related to biodegradation of fluoride compounds.

Fluoride contamination, consequences and removal techniques in water: a review

“…The costeffectiveness, availability, practicality, and deuoridation efficiency of a specic type of bio adsorbent play a role in its selection. 404 The contaminants linked to biomass are oen eradicated, and the bio-adsorbents are repeatedly rejuvenated. 405 Granular bio-adsorbents are helpful because they work 410 Different resistance mechanisms, namely bioaccumulation and biotransformation, allow some bacterial species to tolerate greater F − concentrations.…”

Bioaccumulation of Fluoride in Plants and Its Microbially Assisted Remediation: A Review of Biological Processes and Technological Performance

“…Moreover, consortia, i.e., binary setups using microbes, should be used for removal purposes [103]. Efficient fluoride-degrading organisms should be emphasized to commercialize the fluoride remediation method [281]. Removing contaminated organisms from water bodies should also be an integral part of the bioremediation process [281].…”

“…Efficient fluoride-degrading organisms should be emphasized to commercialize the fluoride remediation method [281]. Removing contaminated organisms from water bodies should also be an integral part of the bioremediation process [281]. There are some potential future perspectives that should be considered for further studies using the microbial remediation method for fluoride removal:…”

Alternative Strategies for Microbial Remediation of Pollutants via Synthetic Biology

“…The data related to end products and intermediate metabolites released throughout degradation pathways can also be retrieved (Dvoøák et al, 2017). An extended information source linked to degradation is MetaRouter, allowing data (Singh and Gothalwal, 2018) for life sciences laboratories to explore degradation possibilities of recalcitrant compounds (Mohanta et al, 2015). The information on oxygenic degradation of xenobiotics can be retrieved from OxDBase, a biodegradative oxygenase database (Chakraborty et al, 2014;Shah et al, 2018).…”
