Heavy metal contamination is a universal problem that disrupts the environment as a consequence of several anthropogenic activities. This chapter provides a review on the remediation technologies of heavy metal contamination. The modern remediation techniques of heavy metal from the contaminated soil and water are expensive and environmentally dest...

Wetlands are one of the most threatened of all biomes on earth. Coimbatore is an important industrial city of India which is located on the banks of the river Noyyal. Presently, there are 28 wetlands mostly fed by the river Noyyal. The prevailing drainage and sewerage system open into the adjoining wetlands and the river Noyyal without appropriate...

It is evident that cultural eutrophication (i.e. human induced) is an important environmental problem that the city water bodies are now facing. While the literature informs us about the importance and status of the lakes in Coimbatore city, it also highlights the gaps in the information base. So far, no long-term studies as well as research coveri...

Chromium-resistant plant growth-promoting bacteria (PGPB) were isolated from the electroplating industry waste disposal site soils at Coimbatore, India, using LB medium. The strain tolerated chromium concentrations up to 500 mg Cr6+L−1 on LB medium. The strain was identified as Pseudomonas sp. VRK3 based on its morphological, physiological, and bio...

The Cr(6+)-resistant plant growth-promoting bacteria was isolated from soil samples that were collected from an electroplating industry at Coimbatore, India, that had tolerated chromium concentrations up to 500 mg Cr(6+)/L in Luria-Bertani medium. Based on morphology, physiology, and biochemical characteristics, the strain was identified as Bacillu...

Heavy metal resistant fungi were isolated from an electroplating industrial effluent samples that uses copper, cadmium and lead for plating. These isolates were tested to evaluate their applicability for heavy metal removal from industrial wastewaters. Initially the physico-chemical parameters of the samples were analyzed. The optimum conditions of...

Assessment of high-density polyethylene (HDPE)-degrading bacteria isolated from plastic waste dumpsites of Gulf of Mannar. Rationally, 15 bacteria (GMB1-GMB15) were isolated by enrichment technique. GMB5 and GMB7 were selected for further studies based on their efficiency to degrade the HDPE and identified as Arthrobacter sp. and Pseudomonas sp., r...

Microorganisms play a vital role in heavy metal contaminated soil and wastewater by the mechanisms of biosorption. In this study, heavy metal resistant bacteria were isolated from an electroplating industrial effluent samples that uses copper, cadmium and lead for plating. These isolates were characterized to evaluate their applicability for heavy...
