Abstract:

Dissertation for the obtention of the Master Degree in Biotechnology<br>Nanobiotechnology is an emerging area full of potentialities to explore and reshape instituted knowledge. In this work, the main goal was to design and test biological remediation systems (a total of three) taking advantage of nanotechnology features, as a step towards future progress of sense-and-shoot combined systems. This task involved the development of active bionanoconjugates (BNC) with two different tyrosinases (Agaricus bisporus - AbT, and Tricoderma reesei - TrT) to be implemented in three suggested phenol rem

Abstract:

A range of tools have been proposed to support decision making in contaminated land remediation (collectively referred to as Decision Support Tools or DSTs). From a European perspective it is clear, however, that there are considerable national differences in the decision support process, and more generally in the extent to which this process supports the se lection of less invasive, alternative and potentially more sustainable remediation options such as phytoremediation, in situ immobilisation etc. (referred to here as "gentle" remediation technologies or options).

Abstract:

The aim of this research is to investigate the remediation of Methyl Tertiary Butyl Ether (MTBE) and other organics in groundwater by applying photocatalysis as an in-situ process. Photocatalytic degradations of MTBE and some other organics pollutants were proved to be possible. Experimental results suggest that photocatalytic degradation is accurately described by first order kinetics. The efficiency of photocatalytic degradation was expressed as the rate constant or the quantum yield. It was found that complete photocatalytic degradation of MTBE was only possible under aerobic conditions. In

Abstract:

Many industrial effluents are toxic, difficult to treat and contain potentially valuable resources. Current treatment methods are expensive and unsustainable. Bioprocessing is a promising alternative, but poses multiple challenges due to the chemically complex nature and high variability of different industrial effluents. As a result, it benefits from being combined with advanced oxidation processes. In this study, the potential benefit of coupling bioprocessing with nanoscale zero-valent iron and electron beam treatment was examined. Both processes have shown great promise individually in env
