Aerobic degradation of highly chlorinated polychlorobiphenyls by a marine bacterium, Pseudomonas CH07
De, J.; Ramaiah, N.; Sarkar, A. (Springer, 2006)Hitherto, aerobic degradation of polychlorinated biphenyls (PCBs) has been reported to be limited to the less chlorinated biphenyls. A marine mercury-resistant bacterium, Pseudomonas CH07 (NRRL B-30604) which was capable ... -
Bioremediation of toxic substances by mercury resistant marine bacteria
De, J.; Sarkar, A.; Ramaiah, N. (Elsevier, 2006)Bioremediation of toxic substances includes microbe-mediated enzymatic transformation of toxicants to non-toxic, often assimilable, forms. Mercury-resistant marine bacteria are found to be very promising in dealing with ... -
Characterization of marine bacteria highly resistant to mercury exhibiting multiple resistances to toxic chemicals
De, J.; Ramaiah, N. (Elsevier, 2007)Several strains of bacteria unusually highly resistant to mercury were isolated from seawater and marine sediment samples and identified by 16S rDNA sequencing and were also characterized by a battery of biochemical and ... -
Detoxification of toxic heavy metals by marine bacteria highly resistant to mercury
De, J.; Ramaiah, N.; Vardanyan, L. (Springer, 2008)Pollution in industrial areas is a serious environmental concern, and interest in bacterial resistance to heavy metals is of practical significance. Mercury (Hg), Cadmium (Cd), and lead (Pb) are known to cause damage to ... -
Environmental pollution detection and bioremediation by marine bacteria
Ramaiah, N.; De, J.; Iyer, S.R. (Discovery Publishing House, 2003)Microorganisms, in particular bacteria, play far more important ecological roles in natural environments than their small sizes would suggest. The environment for bacteria is everything that surrounds and sustains them ... -
Mercury-Resistant Marine Bacteria and their Role in Bioremediation of Certain Toxicants
De, J. (2004)The primary objective of this study was to isolate and enumerate mercury-resistant bacteria and to compare their occurrence and distribution spatially and temporally along the Indian coasts. As coastal waters experience ... -
Occurrence of large fractions of mercury-resistant bacteria in the Bay of Bengal
De, J.; Ramaiah, N. (Indian Academy of Sciences, 2006)As insights from tolerance responses of native microflora are useful in deciphering their involvement in biogeochemical cycling of heavy metals, we enumerated mercury resistant bacteria (MRB) using sea water nutrient agar ... -
Potential of mercury-resistant marine bacteria for detoxification of chemicals of environmental concern
De, J.; Ramaiah, N.; Bhosle, N.B.; Garg, A.; Vardanyan, L.; Nagle, V.L.; Fukami, K. (The Japanese Society of Microbial Ecology, 2007)The hypothesis that mercury-resistant bacteria exposed to polluted environments such as coastal areas can tolerate, detoxify, or biotransform a variety of other toxicants was examined. Several mercury-resistant marine ... -
Removal of mercury in fixed-bed continuous upflow reactors by mercury-resistant bacteria and effect of sodium chloride on their performance
De, J.; Leonhauser, J.; Vardanyan, L. (Bloomsbury Qatar Foundation, 2014)Urgent need to reduce the amount of toxic mercury compounds in the wastewater of industries and subsequent reuse of metal ions, has led to an increasing interest in microbial bioremediation. Two Pseudomonas aeruginosa ... -
Tolerance to various toxicants by marine bacteria highly resistant to mercury
De, J.; Ramaiah, N.; Mesquita, A.; Verlecar, X.N. (Springer, 2003)Bacteria highly resistant to mercury isolated from seawater and sediment samples were tested for growth in the presence of different heavy metals, pesticides, phenol, formaldehyde, formic acid, and trichloroethane to ... -
Unusual rise in mercury-resistant bacteria in coastal environs
Ramaiah, N.; De, J. (Springer, 2003)A sharp rise in mercury-resistant bacteria (MRB) capable of tolerating very high concentration of Hg was observed over the last 3-4 years in the coastal environs of India. While none or negligible colony-forming units (CFU) ...
