In this paper, the microbial characteristics of the granular sludge in the presence of oxygen (3.0+/-0.7 mg O2 l(-1)) were analyzed using molecular biology techniques. The granules were provided by an upflow anaerobic sludge blanket (UASB) operated over 469 days and fed with synthetic substrate. Ethanol and sulfate were added to obtain different COD/SO4(2-) ratios (3.0, 2.0, and 1.6). The results of fluorescent in situ hybridization (FISH) analyses showed that archaeal cells, detected by the… Expand

Application of horizontal-flow anaerobic immobilized biomass reactor for bioremediation of acid mine drainage.
TLDR
Results showed that a maximal efficiency in the removal of sulfate and ethanol could only be obtained by reducing the applied sulfate load, and this strategy led to over 75% of chemical oxygen demand (COD) and sulfate removal. Expand
High rate of biological removal of sulfate, organic matter and metals in uabs reactor to treat synthetic acid mine drainage and cheese whey wastewater as carbon source.
TLDR
An upflow anaerobic sludge blanket (UASB) reactor is used to co-treat a low-pH synthetic AMD and cheese whey wastewater (CWW) and the use of a single reactor to treat AMD and CWW is promising. Expand

TLDR
The prevalence and spatial distribution of archaeal communities in biofilm-based WWT as well as their role in biofouling are reviewed here, in order to illustrate the significance of this prokaryotic cellular lineage in engineered environments devoted to WWT. Expand
Sulfate and metals removal from acid mine drainage in a horizontal anaerobic immobilized biomass (HAIB) reactor
TLDR
Higher sulfate and COD concentrations associated with higher hydraulic retention times (36 h) proved to be a better strategy for sulfate removal, and the HAIB reactor proved a suitable alternative for reaching high levels of metal removal. Expand
