Three commonly used dyes, Acid Red-114 (AR-114), Reactive Black-5 (RB-5), and Disperse Black EX-SF (DB-EX-SF), were treated in a pH-neutral liquid with ultraviolet (UV) light by two reactive methods: photocatalysis with titanium dioxide (TiO2), and/or chemocatalysis with hydrogen peroxide (H2O2) as the oxidant and various ferrous-based electron med...

The dynamic of microbial community plays vital role during composting. We therefore conducted a combined study on the maturity of compost (by pig manure composting with covering matured compost) and the successions of microbial communities (via phospholipid fatty acid (PLFA)). Our results showed that pH, electrical conductivity (EC), NH4-N, and ger...

A hypersaline dissimilatory sulphate reducing bacterium, strain LS4, isolated from the sediments of Ribander saltpan, Goa, India was found to produce (Fe2O3) maghemite nanoparticles. The presence of maghemite nanoparticles was also detected in the same sediment. Strain LS4 was isolated anaerobically on modified Hatchikian's media at 300 psu, growin...

Guwahati, the capital city of Assam and the gateway to the seven north-eastern Indian states, is located in the Brahmaputra valley-one of the most flood prone regions of the world. The city receives an average annual rainfall of 1688 mm and is highly vulnerable towards frequent urban floods because of uncontrolled dumping of solid waste and siltati...

Humic substances (HS) are redox-active and can function as organic terminal electron acceptors in anaerobic microbial respiration, which plays a relevant role on suppressing the emissions of methane (CH4) in anoxic systems. However, it is unclear whether or not there is an inherent link between suppression of CH4 emissions by HS and warming tempera...

Impervious surfaces are mainly artificial structures such as rooftops, roads, and parking lots that are covered by impenetrable materials. These surfaces are becoming the major causes of nonpoint source (NPS) pollution in urban areas. The rapid progress of urban development is increasing the total amount of impervious surfaces and NPS pollution. Th...

The rapid exploitation of coastal and marine ecosystemic capital is on course to reach a critical point. The difficulty of implementing Integrated and ecosystem based management models, taking into the account the great complexity of the marine socio-ecological systems, has resulted in a significant gap between theory and practice. The majority of ...

Resource-oriented sanitation (ROS) systems play an important role in handling source-separated human sanitary wastes intended to be used for other purposes. Usually, the purpose of employing such systems is to render the source-separated human feces suitable as fertilizer or soil conditioner. However, the high volume, low degradation rate, and lack...

Cationic surfactants such as benzalkonium chlorides (BACs) are used extensively as biocides in hospitals, food processing industries, and personal care products. BACs have the potential to reach the rooting zone of crop plants and BACs might thereby enter the food chain. The two most commonly used BACs, benzyl dimethyl dodecyl ammonium chloride (BD...

Forest management practices in Mediterranean ecosystems are frequently employed to reduce both the risk and severity of wildfires. However, these pre-fire treatments may influence the effects of wildfire events on soil properties. The aim of this study is to examine the short-term effects of a wildfire that broke out in 2015 on the soil properties ...
