Simultaneous Electricity Generation and Sulfur Removal by Electrogenic Sulfate Reducing Bacteria in BES System
The modern BioElectrochemical technologies can convert the energy stored in the chemical bonds of biodegradable organic materials to renewable electrical energy through the catalytic reactions of microorganisms while treating the waste waters. The present research was conducted to evaluate the efficiency of a single-chamber Bioelectrochemical system with the carbon aerogel catalyst, as a simple...
متن کاملRemoval of Metal Ions from Mine Effluents Using Bacterial Reactions by Sulfate Reducing Bacteria
Metals in mine effluents, especially metal mines, have been a major environmental concern. High mobility of the metals in solution and the subsequent lowering of discharge limits by the EPA have necessitated expensive chemical treatment of the effluent. Bacteriological reactions, particularly by Sulfate Reducing Bacteria, have been known to reduce metals content in water by precipitating them a...
متن کاملQuantifying Heavy Metals Sequestration by Sulfate-Reducing Bacteria in an Acid Mine Drainage-Contaminated Natural Wetland
Bioremediation strategies that depend on bacterial sulfate reduction for heavy metals remediation harness the reactivity of these metals with biogenic aqueous sulfide. Quantitative knowledge of the degree to which specific toxic metals are partitioned into various sulfide, oxide, or other phases is important for predicting the long-term mobility of these metals under environmental conditions. H...
متن کاملPromotion of Ni2+ Removal by Masking Toxicity to Sulfate-Reducing Bacteria: Addition of Citrate
The sulfate-reducing bioprocess is a promising technology for the treatment of heavy metal-containing wastewater. This work was conducted to investigate the possibility of promoting heavy metal removal by the addition of citrate to mask Ni2+ toxicity to sulfate-reducing bacteria (SRB) in batch reactors. SRB growth was completely inhibited in Ni2+-containing medium (1 mM) when lactate served as ...
متن کاملModeling in-situ uranium(VI) bioreduction by sulfate-reducing bacteria.
We present a travel-time based reactive transport model to simulate an in-situ bioremediation experiment for demonstrating enhanced bioreduction of uranium(VI). The model considers aquatic equilibrium chemistry of uranium and other groundwater constituents, uranium sorption and precipitation, and the microbial reduction of nitrate, sulfate and U(VI). Kinetic sorption/desorption of U(VI) is char...
