Abstract:

Pentachloronitrobenzene (PCNB) is an organochlorine fungicide used either as seed dressing or for soil treatment. Research was conducted to investigate the microbial reductive transformation of PCNB with cultures developed from a contaminated estuarine sediment. The biotransformation of PCNB to pentachloroaniline (PCA) occurred under all electron accepting conditions tested. Sequential dechlorination of PCA to di- and in some cases to mono-chlorinated anilines occurred under fermentative/methanogenic conditions. Based on the use of inhibitors, methanogens were not involved in the sequential de

Abstract:

Mono- and di-alkyltins are used extensively as heat stabilizers for processing of poly vinyl chloride (PVC). Tin mercaptide stabilizers are some of the most effective PVC stabilizers available. The main applications for tin stabilizers are building/construction products, such as pipes, fittings, siding and profiles (windows etc.), packaging and flexible PVC plastics. Most PVC products have been and are subjected to landfilling, when their use is terminated. The structure of the polymer itself and the substances used as additives have been a concern for environmental authorities in many countri

Abstract:

Arsenic (As) is a common occurring environmental pollutant. The USEPA has a stricter regulation for arsenic in drinking water (10 ug/L). Small drinking water suppliers from regions with high arsenic backgrounds levels, will need to remove arsenic from drinking water in order to meet the new standard. The proposed treatment by the USEPA is the oxidation of arsenite (AsIII) to arsenate (AsV) followed by the adsorption onto metal oxides (e.g. granular ferrihydrite (GFH)). Large amounts of arsenic-bearing solid waste will be generated and disposed in municipal landfills based on EPA's recommen

Abstract:

In 2015 the average concentration of CO2 in the atmosphere exceeded 400 ppm. Some technologies, including CO2 capture and storage, are palliative. However, the development of alternatives to burning of fossil fuels focuses on the base of the problem and proposes substantial changes in the energy model. This thesis proposes the use of bioelectrochemical systems to transform CO2 into valuable products. This process is known as microbial electrosynthesis, and is based on the use of bacteria able to use the electrode as an electron donor (biocathode) to drive CO2 reduction. The results show that t

Background: Recent research showing how dietary interventions substantially influence the potential presence of widespread and stable bacterial core phyla in the human colon has garnered a considerable amount of attention.

Abstract:

Microbial-Induced Calcium Carbonate (CaCO3) Precipitation (MICP) is a biological process in which microbial activities alter the surrounding aqueous environment and induce CaCO3 precipitation. Because the formed CaCO3 crystals can bond soil particles and improve the mechanical properties of soils such as strength, MICP has been explored for potential engineering applications such as soil stabilisation. However, it has been difficult to control and predict the properties of CaCO3 precipitates, thus making it very challenging to achieve homogeneous MICP-treated soils with the desired mechanical

Abstract:

The sea surface microlayer is a millimeter-scale interfacial layer between the atmosphere and the ocean.

In this work, we present an improved method to sample and compare the bacterial diversity of the sea surface microlayer with that of subsurface water at the same site.

Nitrogen (N) is one of the most essential mineral nutrients often limiting the productive capacity of terrestrial ecosystems. This nutrient is available in different chemical forms in soil which are mostly transformed from one to another through microbially mediated processes. However, the growth and activity of these microbes are often constrained by the availability of phosphorus (P) which is required for the synthesis of their genetic and cellular components, metabolism and energy transfer. Little is known about how P availability affects microbial processes responsible for N transformation
