Reduction of Hexavalent Chromium by Stenotrophomonas and Bacillus [PDF]

Microbiologyopen
Stenotrophomonas and Bacillus remove toxic hexavalent chromium via enzymatic reduction and non‐enzymatic mechanisms. Reductases (e.g., ChrR, HhuH, YhdA, NfrA, Bcr005, NitR, AzoR) use NAD(P)H to convert Cr(VI) to the less toxic Cr(III). ABSTRACT Hexavalent chromium [Cr(VI)] is a widespread environmental pollutant, posing a significant health risk to ...

Media‐Dependent Growth, Stress Responses, and Metal Accumulation Patterns in Azolla imbricata (Roxb.) Nakai Exposed to As, Cd, Cu, Pb, and Zn: Individual and Combination Effects (Synergistic, Antagonistic, and Additive)

Environmental Toxicology, EarlyView.
ABSTRACT In this study, we examined metal accumulation and biochemical responses of Azolla imbricata (Roxb.) Nakai exposed to water medium (WM) and nutrient medium (NM) under single and combined (co‐exposure) treatments with five metals (As, Cd, Cu, Pb, and Zn) at 10% environmentally relevant concentrations.

Application of electro-active biofilms [PDF]

, 2010
The concept of an electro-active biofilm (EAB) has recently emerged from a few studies that discovered that certain bacteria which form biofilms on conductive materials can achieve a direct electrochemical connection with the electrode surface using it ...

Microbial Community Dynamics in Marine Water: Influence of Hydrocarbon Type and Exposure Time

Environmental Toxicology, EarlyView.
ABSTRACT Marine environments are frequently impacted by petroleum‐derived hydrocarbons, which pose ecological risks because of their toxic, mutagenic, and carcinogenic potential. Microorganisms play a crucial role in hydrocarbon degradation, and understanding the influence of time and hydrocarbon type on microbial dynamics helps improve bioremediation ...

Genetic benefits of female from extra-pair paternity are context dependent within the socially monogamous Tree Sparrow

Avian Research
Females actively seek extra-pair paternity (EPP) to acquire a fitness advantage for their offspring. The “context-dependence hypothesis” posits that female extra-pair mate choice has plasticity in response to environmental conditions, and therefore ...

Assessment of Oxidative Stress, Vitellogenin, and Human Health Risks Derived From Nile Tilapia Exposed to Metals and Metalloids in Southeastern Brazil

Environmental Toxicology, EarlyView.
ABSTRACT Urban coastal lagoons are highly vulnerable ecosystems increasingly affected by metal contamination, as well as multiple anthropogenic stressors. This study evaluated ecotoxicological and human health risks associated with chronic metal exposure in Nile tilapia (Oreochromis niloticus) from an anthropogenically impacted lagoon in southeastern ...

THE AESTHETICS OF URBAN METABOLISM: Landscape, Design and the Politics of In/Visibility

International Journal of Urban and Regional Research, EarlyView.
Abstract In this article, we chart the evolving aesthetic contours of urban metabolism across London, focusing on the River Lea and Thamesmead to the north and south of the River Thames, respectively. We begin in the nineteenth century, when these two sites formed critical nodes within a new sewerage system that relegated the city’s circulatory flows ...
