Health hazards of hexavalent chromium (Cr (VI)) and its microbial reduction

Bioengineered, Journal Year: 2022, Volume and Issue: 13(3), P. 4923 - 4938

Published: Feb. 14, 2022

Industrial effluents/wastewater are the main sources of hexavalent chromium (Cr (VI)) pollutants in environment. Cr (VI) pollution has become one world's most serious environmental concerns due to its long persistence environment and highly deadly nature living organisms. To widespread use industries is toxic common contaminants. frequently non-biodegradable nature, which means it stays for a time, pollutes soil water, poses substantial health risks humans wildlife. In things, form carcinogenic, genotoxic, mutagenic. Physico-chemical techniques currently used removal not environmentally friendly large number chemicals. Microbes have many natural or acquired mechanisms combat toxicity, such as biosorption, reduction, subsequent efflux, bioaccumulation. This review focuses on microbial responses toxicity potential their remediation. Moreover, research problem prospects future discussed order fill these gaps overcome associated with bacterial bioremediation's real-time applicability.

Zinc Essentiality, Toxicity, and Its Bacterial Bioremediation: A Comprehensive Insight

Frontiers in Microbiology, Journal Year: 2022, Volume and Issue: 13

Published: May 31, 2022

Zinc (Zn) is one of the most abundantly found heavy metals in Earth’s crust and reported to be an essential trace metal required for growth living beings, with it being a cofactor major proteins, mediating regulation several immunomodulatory functions. However, its essentiality also runs parallel toxicity, which induced through various anthropogenic sources, constant exposure polluted sites, other natural phenomena. The bioavailability Zn attributable vegetables, beef, dairy products, are good source safe consumption by humans. conditions toxicity can occur overdosage supplements, increasing at alarming rate attributing lack awareness. Though humans treatable non-life-threatening condition, symptoms cause distress human activities lifestyle, including fever, breathing difficulty, nausea, chest pain, cough. In environment, generally soil water bodies, where introduced action weathering, release industrial effluents, respectively. Excessive levels these sources alter aquatic microbial diversity, thus affect absorption as well. Several Gram-positive -negative species, such Bacillus sp., Staphylococcus Streptococcus Escherichia coli , Pseudomonas Klebsiella Enterobacter respectively, have been promising agents bioremediation. This review intends present overview properties, uses, bioavailability, well mechanisms involved bioremediation from wastewaters.

Biochar-microorganism interactions for organic pollutant remediation: Challenges and perspectives

Environmental Pollution, Journal Year: 2022, Volume and Issue: 308, P. 119609 - 119609

Published: June 11, 2022

Numerous harmful chemicals are introduced every year in the environment through anthropogenic and geological activities raising global concerns of their ecotoxicological effects decontamination strategies. Biochar technology has been recognized as an important pillar for recycling biomass, contributing to carbon capture bioenergy industries, remediation contaminated soil, sediments water. This paper aims critically review application potential biochar with a special focus on synergistic antagonistic contaminant-degrading microorganisms single mixed-contaminated systems. Owing high specific surface area, porous structure, compatible chemistry, can support proliferation activity microorganisms. A combination remove variety contaminants gained popularity recent years alongside traditional chemical physical technologies. The microbial compatibility be improved by optimizing parameters so that toxic pollutant release is minimized, biofilm formation encouraged, populations enhanced. Biocompatible thus shows bioremediation organic harboring populations, releasing enzymes, protecting beneficial from immediate toxicity surrounding contaminants. recommends biochar-microorganism co-deployment holds great removal thereby reducing risk human environmental health.
