Lead pollution and bacterial bioremediation: a review

Green Biotechnology of Oyster Mushroom (Pleurotus ostreatus L.): A Sustainable Strategy for Myco-Remediation and Bio-Fermentation

“…Environmental pollution is a global unsolved health issue, which requires advanced strategies through the remediation of soil, water, sediment, and air. This pollution can result from organic pollutants, such as petroleum [67], or inorganic pollutants, such as metal/metalloids (i.e., lead) [68]. These pollutants represent a potential threat to human health, which needs bioremediation by micro-organisms (bacterial, fungi, and algae), phytoremediation by plants, or nano-bioremediation by micro-organisms in the presence of nanoparticles.…”

Contribution, Composition, and Structure of EPS by In Vivo Exposure to Elucidate the Mechanisms of Nanoparticle-Enhanced Bioremediation to Metals

“…Metals such as Cd and Pb are potentially hazardous to the environment and deleterious to human health. , Microorganisms have been extensively studied to reduce the toxicity of metals due to their ability in metal resistance, adsorption, or speciation . Intracellular mechanism (including efflux, complexation, or biotransformation) and extracellular mechanisms (metals chelated by certain polymeric substances such as metallothionein, siderophore, and extracellular polymeric substances) have been reported in the metal bioremediation process. − Among these detoxification strategies, extracellular polymeric substances (EPS) act as an important, initial defense against metals, and is one of the most important approaches used by microbes to protect cells from metal toxicity, and toxic nanoparticles (NPs). − Many bacteria such as Bacillus sp., Pseudomonas sp., Azotobacter sp., Escherichia coli , Mycobacterium sp., and Halomonas sp. have been frequently reported to produce EPS for bioremediation of metals. ,, Halomonas sp.…”

Amplification of the Fluorescence Signal with Clustered Regularly Interspaced Short Palindromic Repeats-Cas12a Based on Au Nanoparticle-DNAzyme Probe and On-Site Detection of Pb2+ Via the Photonic Crystal Chip

“…The lead ion (Pb 2+ ), one of the most poisonous metals in the natural environment, seriously damages human health. , Pb 2+ can be enriched in humans through environmental media, which causes irreversible injury to the human brain, nervous system, cardiovascular system, reproductive system, and so on, resulting in various human diseases. , Therefore, it is essential to construct highly sensitive, selective, low-cost, and accessible methods to detect Pb 2+ both in the environment and humans to safeguard human health. Conventionally, Pb 2+ detection methods are mainly performed by expensive instruments, such as atomic absorption spectroscopy (AAS), atomic emission spectroscopy (AES), and inductively coupled plasma mass spectrometry (ICP-MS) methods .…”
