The efficiency of microbial populations in degrading refractory pollutants and the impact of
adverse environmental factors often presents challenges for the biological treatment of azo …

Continuous excessive irrigation and industrial activities increase the salinity in the
environment which poses a threat to the current technology used in the Methyl Red …

Azo dye reduction by syntrophic microbial communities is still unclear, with conflicting
observations reported in the literature. In this study, the biodegradation mechanism of a …

The uncontrolled release of untreated dyeing wastewater into aquatic ecosystems poses
global environmental risks. It alters native microbial communities and associated ecological …

The bio-reduction of azo dyes is significantly dependent on the availability of electron
donors and external redox mediators. In this study, the natural henna plant biomass was …

Most studies on the biodegradation of textile azo dyes use color as parameter for measuring
the efficiency of degradation. Although widely employed, spectrophotometric methods are …

This work investigated the operational and microbiological aspects of the decolorization of
the azo dye Reactive Black 5 in acidogenic reactors followed by aerobic granular sludge …

Energy recovery from low-strength wastewater through anaerobic methanogenesis is
constrained by limited substrate availability. The development of efficient methanogenic …

Carbon-based materials that serve as microbial carriers, and the role of surface-formed
biofilms in anaerobic digestion, merit further investigation. This study explored the role and …

Modern industrialization has high demand for dyes to impart better color to cosmetic, paper,
textile and pharmaceutical industry. Dyes are of several kinds depending on the base of …
