Master's thesis of Engineering: Application of white-rot fungi for the biodegradation of natural organic matter in wastes

The research herein builds on the work of Rojek (2003) and further investigates the bioremediation of NOM wastes. The aim of this research was to evaluate the effectiveness of selected white-rot fungi and yeast for the biodegradative removal of concentrated NOM from solution. The effectiveness of the white-rot fungus P. chrysosporium ATCC 34541 for the biological degradation of different batches of MIEXTM NOM concentrate and the effects of different characteristics of the NOM on the process and thus the resistance of the NOM to microbial removal were investigated.

Master's thesis of Applied Sciences: The use of the integrated soil microcosms to assess accumulation of caesium (Cs) and lead (Pb) from contaminated soils by earthworms (Eisenia andrei) and the sunflower (Helianthus annuus)

In this study the earthworm Eisenia andrei and sunflower dwarf sensation (Helianthus annuus) were used as tools to accumulate Pb and stable Cs. The aim of this study was to evaluate bioremediating Cs and Pb in contaminated soils using the selected biota. The efficacy of this bioremediation was evaluated using integrated soil microcosms (ISM)–a multispecies mini ecosystem with soil contaminated with Cs alone at 25 mg/kg and 250 mg/kg; Pb alone (1500 mg/kg) and Pb (1500 mg/kg) together with Cs (250 mg/kg) in the laboratory.

Characterization of mercury bioremediation by transgenic bacteria expressing metallothionein and polyphosphate kinase

Bioremediation presents a potentially low cost and environmentally agreeable alternative to current physico-chemical remediation strategies. However, heavy metals such as mercury cannot be converted into non-toxic forms by naturally occurring bacteria. Annual global emissions estimates for mercury released into the environment are in the thousands of tons per year [1,2] while the remediation cost is in the thousands of dollars per pound. Finding new bioremediation technologies is an urgent need.

Báo cáo khoa học: The role of residue Thr249 in modulating the catalytic efﬁciency and substrate speciﬁcity of catechol-2,3-dioxygenase from Pseudomonas stutzeri OX1

Bioremediation strategies use microorganisms to remove hazardous sub-stances, such as aromatic molecules, from polluted sites. The applicability of these techniques would greatly benefit from the expansion of the cata-bolic ability of these bacteria in transforming a variety of aromatic com-pounds.
