Heavy Metal Concentration from Shrimp Culture Ponds at Point Calimer Area

چکیده
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 through the way of bioremediation, bioaccumulation and mineralization process. The highest inhibition zone was absorbed in Pseudomonas aeruginosa against Hg (3.796 mm) and Cu (0.060 mm), Aeromonas hydrophila against Pb (5.526 mm) and Bacillus cereus against Zn (4.504 mm) and Fe (1.635 mm). No inhibition zone was produced by Azotobacter beijerinckii and control also maintained.

متن کاملAssessing metal pollution in ponds constructed for controlling runoff from reclaimed coal mines.
Constructing ponds to protect downstream ecosystems is a common practice in opencast coal mine reclamation. As these ponds remain integrated in the landscape, it is important to evaluate the extent of the effect of mine pollution on these ecosystems. However, this point has not been sufficiently addressed in the literature. The main objective of this work was to explore the metal pollution in m...
