Influence of heavy metal supplementation on specific methanogenic activity and microbial communities detected in batch anaerobic digesters.
Natural and modified zeolites (0.5-1.0 mm) from the Tasajera deposit in Cuba were used to enhance the anaerobic digestion process of synthetic substrates. Natural zeolites were modified by ionic exchange and by adsorption with nickel, cobalt and magnesium. The experiments were carried out by using an inoculum from a full-scale anaerobic reactor treating winery wastewater. Modified natural zeoli...
متن کاملeffects of antibiotics on specific methanogenic activity of anaerobic biomass
background: the antibiotics are excreted after their effect on the host body and together with other waste disposal are entered the treatment plant processes. antibiotics prevent the biological sewage treatment in the plant which consequently causes hazards to the environmental and human health. the purpose of this study was to investigate the effect of some popular antibiotics used by human an...
متن کاملComparative Analysis of Methanogenic Communities in Different Laboratory-Scale Anaerobic Digesters
Comparative analysis of methanogenic archaea compositions and dynamics in 11 laboratory-scale continuous stirred tank reactors fed with different agricultural materials (chicken manure, cattle manure, maize straw, maize silage, distillers grains, and Jatropha press cake) was carried out by analysis of the methyl coenzyme-M reductase α-subunit (mcrA) gene. Various taxa within Methanomicrobiales,...
متن کاملEffects of heavy metal pollution on the soil microbial activity
The effects of heavy metals on soil microbial processes were investigated over a period of six weeks. Analytical grade (Sigma) sulphate salts of copper, zinc and nickel were added individually and in combinations to soil samples and incubated in different plastic pots. Samples were taken from the pots forthnightly and the rates of microbial carbon and nitrogen mineralization, microbial biomass ...
