Abstract:

Nitrogen (N) is an essential nutrient for plant growth and therefore a detailed mechanistic understanding of soil N cycling and plant N uptake is necessary to ensure sustainable food production. In addition, N availability can have significant effects on vegetation community structure and therefore climate-change induced shifts in N availability could affect ecosystem functioning and climate change feedbacks. The potential importance of organic N for plant nutrition has only recently been realised, and knowledge of its cycling and the competition for this resource in plant-soil systems is lack

Gene transfer plays an important role in bacterial evolution. Especially in an under explored species like Rhodococcus, a type of bacteria found in the soil. Rhodococcus has several applications in the pharmaceutical industry and in the production of antibiotics. Rhodococcus possess several unique sets of properties which makes it beneficial to have a reliable method of producing mutants of Rhodococcus. The goal of the experiment was to find an efficient way of forming Rhodococcus colonies with kanamycin resistant genes. The project began from an unexpected observation from an earlier experime

Veterinary pharmaceuticals are routinely used in livestock production to treat diseases, prevent infections, and promote growth.

A better understanding of the environmental fate of veterinary pharmaceuticals is critical to properly assess and mitigate their risks. This dissertation focuses on a major group of veterinary phar

Abstract:

A model for the transformation of methane or vinyl chloride by methanotrophic bacteria in unsaturated sand columns was proposed. The model was based on Michaelis-Menten kinetics. The columns were successful in transforming methane and vinyl chloride at a remarkably high rate. Vinyl chloride was transformed only in the obligate presence of methane, as the two are in competition for the enzyme responsible for transformation. The model was highly sensitive to estimated methanotrophic biomass concentration. Water content was not inhibitory between 0.04 and 0.39 volumetric water content. Interphase

Abstract:

Dynamic soil-structure interaction problems are characterized by an unbounded soil-domain and thus by radiation damping. This radiation damping arises due to wave propagation from the excited structure into the subsoil and may lead to a reduction of the structural response. A consistent description of this radiation damping has been carried out by means of different concepts. A widely used approach truncates the unbounded medium by a special kind of absorbing boundaries which are free of artificial reflection. The resulting finite domain can be treated as usually by finite elements. In this re

Abstract:

Soil that is heavily contaminated with polycyclic aromatic hydrocarbons (PAHs) is often found at the sites of former gasworks and wood-impregnation plants. Since PAHs are toxic these sites represent a hazard to human health and the environment, and therefore they need to be treated, preferably by a method that destroys the contaminants, and thus eliminates the problem permanently. However, during biological and chemical degradation of PAHs other toxic compounds may be formed. If these transformation products are sufficiently persistent they could potentially accumulate during remedial processe

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:

A study was made of the effects of adding a range of silicon compounds (of potential use as fertilizers) to a variety of different soils. In addition the solubilization of insoluble silicon compounds by bacteria and a species of Penicillium isolated from ferns growing in walls (as a likely silicon-rich environment) was determined. The results of the present study show that: 1) Bacteria solubilize rock potash, releasing free silicon into the medium. 2) Growth of a Penicillium Sp. in vitro increases the solubilization of sodium silicate, but concentrations of free silicon decrease when the fungu

Abstract:

The work presented in this thesis explores the potential role of bacteria in the arsenic cycle an agricultural soil from Scarlino (Tuscany), and a soil from Torviscosa (Fiuli), pyrite cinders contaminated. Both soils contained high levels of total arsenic. The soil of Scarlino contained 250 mg kg-1, mainly associated to iron oxides (70% of the total), while the labile forms were 10% of the total. Total As in the soil of Torviscosa was 446 mg kg-1, mainly present in the residual phase (50% of the total), while the labile forms represented 15% of the total. This thesis started to investigate t
