Natural heterogeneous catalysis with immobilised oxidase biocatalysts

Studies on Production of Glucose Oxidase using Immobilised Thermophilic Microorganisms

Heterogeneous asymmetric catalysis*

Examples of enantioselective catalysts, including homogeneous supported catalysts and biphasic liquid/liquid, are described and compared. In the case of asymmetric hydride transfer, polythiourea was proven to be more efficient for ruthenium-catalyzed reduction of aryl ketones, although the iridium complexes gave rise to higher ee when using amino sulfonamide bound to a polystyrene matrix. In th...

Biocatalysts in Cancer Tissue III. Succinic Dehydrogenase and Cytochrome Oxidase*

The accumulation of lactic acid in tumor tissue (15) suggests an inadequacy in the oxidative mechanism. A deficiency of one of the components of the oxidative mechanism, cytochrome c, was demonstrated in the first paper of this series (6). The present article reports the decreased activities of succinic dehydrogenase and of cytochrome oxidase in tumor tissues. These enzymes together with cytoch...

Heterogeneous Catalysis for Environmental Remediation

The intensive human activities in chemical industry and environmental purification urge the development of advanced protocols for green production and waste management. In environmental science, developing highly efficient and environmentally-friendly catalytic materials and systems are very favourable approaches to green chemical synthesis and remediation of contaminated air, soil, and wastewa...

Heterogeneous Catalysis for Tandem Reactions

As long as the molecular complexity increases, the number of chemical transformations will increase in parallel, becoming a highly demanding synthetic process in terms of time and resources. Since the loss of material after each purification step will also dramatically reduce the overall efficiency of a synthetic process, the conversion of such transformation into a practical and efficient proc...
