Anaerobic Digestion (AD) of wastewater for hydrogen production is a promising technology resulting in the generation value-added products and reduction organic load wastewater. The Two-Stage (TSAD) has several advantages over conventional single-stage process due to ability control acidification phase first bioreactor, preventing overloading and/or inhibition methanogenic population second bior...

Wastewater treatment is a very energy-intensive process. The growing population, increased demands for energy and water, rising pollution levels caused by fossil-fuel-based generation, warrants the transition from fossil fuels to renewable energy. This research explored consumption offset of satellite water reuse plant (WRP) using solar photovoltaics (PVs) anaerobic digestion. analysis was perf...

Communities of anaerobic methane-oxidizing archaea (ANME) and sulfate-reducing bacteria (SRB) grow slowly, which limits the ability to perform physiological studies. High methane partial pressure was previously successfully applied to stimulate growth, but it is not clear how different ANME subtypes and associated SRB are affected by it. Here, we report on the growth of ANME-SRB in a membrane c...

22 Anaerobic methane oxidizing communities of archaea (ANME) and sulfate reducing bacteria 23 (SRB) grow slowly, which limits physiological studies. High methane partial pressure was 24 previously successfully applied to stimulate growth, but it is not clear how different ANME 25 subtypes and associated sulfate reducing bacteria (SRB) are affected by it. Here, we report 26 growth of ANME/SRB in...

Basnayake, Rukma ST, Inorganic Selenium and Tellurium Speciation in Aqueous Medium of Biological Samples, Master of Science (Chemistry), December 2001, Sam Houston State University, Huntsville, Texas, 60 pp. Purpose The purpose of this research was to develop methods to study the ability of bacteria, Pseudomonas fluorescens K27 to detoxify tellurium and selenium salts by biotransformation proce...

This study is focused on investigation of biofilms formed in an anaerobic laboratory-scale bioreactor fed with medium for anammox bacteria oxidizing ammonia with nitrite. The mixed culture of anammox bacteria was enriched from the microbial community that sampled from the activated sludge of a denitrifying reactor at a wastewater treatment station located in the Sochi region, Russia. This commu...

Planctomycetes belong to an unique anaerobic ammonia oxidation (anammox) member of the bacteria. They have a special organelle, anammoxosome, for anaerobic ammonia oxidation. Since they grow extremely slowly, there have been some difficulties identifying them. It is only recently that people have discovered planctomycetes might play a role in the process of converting ammonia and nitrite direct...

In the quest for inexpensive feedstocks for the cost-effective production of liquid fuels, we have examined gaseous substrates that could be made available at low cost and sufficiently large scale for industrial fuel production. Here we introduce a new bioconversion scheme that effectively converts syngas, generated from gasification of coal, natural gas, or biomass, into lipids that can be use...
