Environmental biotechnology/microbiology, Biological treatment of water and wastewater
Hydrogen is a promising alternative to fossil fuels. It is a clean, renewable, carbon-free energy carrier of the future. It has a heating value of approximately 2.5 times greater than that of methane and can be used in fuel cells with high efficiency. When combusted, it produces water rather than greenhouse gases. Hydrogen can be derived from various means, chemically or biologically, each with its own set of advantages and disadvantages. Biohydrogen production is an environmentally friendly method employing either natural or genetically-modified microbial communities to produce hydrogen. Prior to the establishment of full-scale biohydrogen production, substantial, fundamental research is needed to address the key capabilities of the system so that high hydrogen production rates and efficiency can be achieved.
ANaerobic AMMonium OXidation (ANAMMOX)
The ANaerobic AMMonium OXidation (ANAMMOX) process involves the use of nitrite as an electron acceptor in the bacterially mediated oxidation of ammonia to yield di-nitrogen gas. The process allows nitrogen transformation similar to the classical processes of nitrification followed by denitrification. However, it reduces oxygen demand and requires no additional organic carbon source as compared to typical nitrification and denitrification, respectively. It is a promising microbial process to remove ammonia from wastewater characterized by a low content of organic materials.
Assimilable Organic Carbon (AOC) and Regrowth Potential in Drinking Water
During the past decade, research interest in drinking water treatment has focused on the biodegradable fraction of organic carbon in natural and treated water. This interest stems from the recognition that biodegradable organic matter in water can provide growth support to microorganisms which can be intensified during storage, and travel within the distribution systems. Such phenomenon is known as biological regrowth, and the fraction of biodegradable organic carbon is commonly termed biodegradable dissolved organic carbon (BDOC) or assimilable organic carbon (AOC). Biological regrowth in distribution systems has been known for years, as a potential cause of corrosion in distribution lines and deterioration of finished water quality, as well as an indirect link to waterborne diseases. It has, however, just come under attention , particularly for developed countries, due to the unclear impact on human health.
