To protect against the environmental pollution, the present research was undertaken to enumerate the Bacterial Technologies (BTs) on the restoration of polluted urban rivers, that is, Fenghu-Song Yang River (FSR) and Xuxi River (XXR). Experimental research accounted for the physiochemical parameters (pH; temperature; dissolved oxygen (DO); chemical oxygen demand (COD); total phosphorus (TP); to...

Sugar mills plays a major role in polluting the water bodies and land by discharging a large amount of wastewater as effluent. The sugar mill effluents are having higher amount of suspended solids, dissolved solids, BOD, COD, chloride sulphate, nitrates, calcium and magnesium. The continuous use of these effluents harmfully affect the crops when used for irrigation. As a result, a higher amount...

Jharia coalfield is one of the most important sources of coking coal in India. Coal mining activities in this coalfield have significantly caused mineralisation of surface and ground water; there-by adversely affecting it’s quality and utility. Several trace elements may be present in mine water released from various mining and processing operations. In this paper, an attempt has been made to a...

A range of fluorescent viability dyes were used in conjunction with flow cytometry to rapidly enumerate viable bacteria from freshwater environments. Optimal labelling was achieved by using carboxyfluorescein diacetate or chemchrome B with a detergent-mediated permeabilization step. The viable bacterial count under optimal conditions was 7% in oligotrophic lake water and 75% in polluted river w...

A 14-month study was carried out to determine the impact of kraft-mill effluents on the offshore benthic macrophyte distribution in a shallow north Florida Bay (USA). A polluted river drainage system was compared to an adjoining (unpolluted) one. The affected area was characterized by elevated levels of color and turbidity. Inshore areas associated with high levels of KME were characterized by ...
