Palk strait estuarine water was highly polluted by Cu, Fe, Pb, Zn and Hg. The study was carryout the interactions between heavy metals and microorganisms. The study area paying attention on the role of probiotic bacteria such as Bacillus cereus, Aeromonas hydrophila, Pseudomonas aeruginosa, Azotobacter vinelandii, and Lactobacillus sp. to remove the metals from polluted nine aquaculture ponds t...

An increasing interest in bioremediation of hydrocarbon polluted sites raises the question of the influence of seasonal and diurnal changes on soil-water temperature on biodegradation of BTEX, a widespread group of (sub)-surface contaminants. Therefore, we investigated the impact of a wide range of varying soil-water temperature on biodegradation of toluene under aerobic conditions. To see the ...
An increasing traffic of over 55,000 ships a year in Turkish seas are producing an average of 12 illegal oil spills a year. Fingerprint analysis is initiated by comparison of fluorometric spectra of polluted sea water sample and suspected source sample. ‘Matching’ is confirmed or rejected by subsequent comparison of FTIR, HPLC and GC-FID. In this study, 39 clean sea waters, 41 polluted sea wate...
The chemical and microbiological properties of Lebanese perennial coastal rivers were studied during the dry season extending from July to September 2004. The results indicate significant levels of pollution in all eight rivers. Although many physical and chemical variables were within WHO guidelines for drinking water, coliform levels were unacceptably high indicating pollution from untreated ...
as opposed to the staining of non-cultivatable organisms of these two genera. Cotton gauze and rayon-polypropylene fiber swabs were equally sensitive for collecting salmonellae from the streams examined. Tetrathionate enrichment incubated at 41.5 C appeared to be superior to selenite-cystine for isolation of salmonellae from surface waters. Twenty-eight serotypes of Salmonella and two serotypes...
Soil microorganisms may be both sensitive and resilient to various disturbances. The effects of a single stressor on soil microorganisms have been well studied, but only limited research has been carried out to test the effects of simultaneous action of diverse stressors. Soil samples were collected from a long-term polluted zinc and lead site and an unpolluted site. Modeling studies assumed sp...
Rivers and Lake are most important water resource in India for purpose like drinking water supplies, irrigation and fisheries. The inland fresh water ecosystem, both lentic and lotic contributes a greater fraction towards the available water resource on the planet which, is now being increasingly subjected to greater stress from various human activities. Present investigation indicated that, Pu...
