Bioremediation of Hexavalent Chromium by Chromium Resistant Bacteria Reduces Phytotoxicity.

Chromium (Cr) (VI) has long been known as an environmental hazard that can be reduced from aqueous solutions through bioremediation by living cells. In this study, we investigated the efficiency of reduction and biosorption of Cr(VI) by chromate resistant bacteria isolated from tannery effluent. From 28 screened Cr(VI) resistant isolates, selected bacterial strain SH-1 was identified as sp.

Occurrence of and faecal coliforms in drinking water at source and household point-of-use in Rohingya camps, Bangladesh.

Background: Safe water is essential for life but unsafe for human consumption if it is contaminated with pathogenic microorganisms. An acceptable quality of water supply (adequate, safe and accessible) must be ensured to all human beings for a healthy life.

Methods: We collected and analyzed a total of 12,650 drinking water samples, for the presence of and faecal coliforms, from a large habitation of the displaced Rohingya population comprising of about 1.
