Microbial Observation in Bioaccumulation of Heavy Metals from the Ash Dyke of Thermal Power Plants of Chhattisgarh, India

Abstract: Several mechanisms are developed by the microorganisms to tolerate few high concentrations of heavy metals. One of these mechanisms dependent upon anabolic and catabolic energy of microorganisms is the bioaccumulation of heavy metals. In present work, approximately four varieties of bacteria have been isolated from the ash dyke sample of four thermal power plants of Chhattisgarh, i.e., Bharat Aluminium Company (BALCO), Chhattisgarh State Electricity Board (CSEB), Korba, Thermal Power Cooperation (NTPC), Bilasp… Show more

“…These are often the Gram-positive Elsilk et al (2014) isolated Bacillus anthracis PS2010, which has variable resistance to heavy metals such as Cd, Cu, Co, Zn and Pb, while Banerjee et al (2015), utilising the serial dilution technique in nutrient medium, isolated B. cereus and B. subtilis. These isolates are resistant to a number of metals -Pb, Hg, Ni, Co, Cu and M (Banerjee et al, 2015). Then, Ansari et al (2016), in their study, isolated from soil six bacteria: Alcaligenes sp.…”

“…The resistance occurred in the following order: Cu > Cr > Zn > Cd. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] and an intertidal zone Matyar, Kaya, and Dinçer [46] studied the sediments of the Iskenderum Bay in Turkey and found bacteria to be more resistant to Cd, followed by Cu and Cr. This discrepancy suggests that there are differences in the heavy metal concentrations in sediments from different areas depending on the surrounding anthropogenic activities.…”

“…This fact is very important, since bacteria are the most abundant organisms in the sediment and represent the first [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] and the intertidal zone steps of toxic component transfer to higher trophic levels [14]. Because of these factors, the results suggest the need for pollution monitoring in the Araça Bay.…”
