The alumina refining industry is one of a number of global industries that produce process waters containing mercury. The research program detailed in this dissertation focuses on processes for removing mercury from Bayer digestion condensate streams. Bayer refinery digestion condensate is chemically unique because it exhibits high pH and is chemically reducing, thermodynamically favouring the presence of elemental mercury.

As the urban area has high population density and intensive anthropogenic activities, there are a great number of sources of heavy metals in cities, placing a considerable influence on human health. Emissions of heavy metals may come from domestic waste, chemical industry and transportation. These emissions have been continuously adding heavy metals to soils and they will remain present for many years even after the pollution sources have been removed.

In petroleum industry, it is desirable to produce lighter hydrocarbons such as gasoline, kerosene and gas–oil from unused heavy oils. Thus we have developed zirconia-supporting iron oxide catalysts View the MathML source to decompose petroleum residual oil (atmospheric distilled residual oil) with steam.

The diseaseFusarium head blight (scab) causes severe problems for farmers and for the industries that use cereals. It is likely that the fungi that cause scab (Fusariumspp.) use various enzymes when they invade grains. We are studying enzymes that the fungi may use to hydrolyze grain proteins. To do this,Fusarium culmorumwas grown in a gluten-con-taining medium from which an alkaline serine proteinase with a molecular mass of 28.7 kDa was puri®ed by size-exclusion and cation exchange chromatographies....

Tocopherols are essential micronutrients in human and animal nutrition due to their function as lipophilic anti-oxidants. Theyare exclusively synthesizedbyphotosynthetic organisms including higher plants. Despite the attributed beneficial health effects and many industrial applications, research on the tocopherol biosynthetic pathway and its regulation inplants is still limited.

Bacillusspecies are valuable producers of industrial enzymes and biophar-maceuticals, because they can secrete large quantities of high-quality pro-teins directly into the growth medium. This requires the concerted action of quality control factors, such as folding catalysts and ‘cleaning proteases’.

Hydantoinases (HYDs) are important enzymes for industrial production of optically pure amino acids, which are widely used as precursors for various semi-synthetic antibiotics. By a process coupling genomic data mining with activity screening, a new hydantoinase, tentatively designated HYDJs, was identified from Jannaschiasp. CCS1 and overexpressed in Escherichia coli.
