The enzyme cellbiose dehydrogenase is a fungal enzyme containing flavin and heme. The catalytically active dehydrogenase domain catalyses the oxidation of cellobiose to cellobionic acid and lactose to lactobionic acid. The enzyme is a dehydrogenase and only reacts poorly with oxygen. A cellobiose oxidase showing improved activity with oxygen would have advantages with respect to various applications. Generating a CDH variant of Myriococcum thermophilum with increased reactivity with oxygen, the neutral pH activity optimum was maintained. It was shown that this variant can convert lactose in milk. It is the aim of the current project to further improve the enzyme for industrial applications.

As part of the project, the microbiota of selected natural sourdoughs is analysed in detail. The dominant lactic acid bacteria and yeasts are isolated, purified, identified, characterized and stored in a strain collection. The aim of the close cooperation with the project partner Versuchsanstalt für Getreideverarbeitung (vg) is the microecological description of the sourdough microbiota with regard to the development of premium bakery products, which should then be made available to the Austrian mills and bakers through the project partner vg.
