Within the scope of the described project, antibiotic resistance genes are detected and identified on plasmids, isolated from Escherichia coli transconjugants by means of a specific microarray-based technique. The plasmids to be investigated were obtained in the context of a previous project by the application of in situ mating with a specific Escherichia coli recipient strain directly from samples, which are assigned to the animal production chain. The applied microarray technique was tailored in a previous research work.

Within the project the microbiota of selected sourdoughs will be analysed in detail. Next to the molecular monitoring of the microecological dynamic of the sourdoughs lactic acid bacteria and yeasts will be isolated, characterised and stored in a strain bank. The aim of the collaboration with the project partner Versuchsanstalt für Getreideverarbeitung (VG) is to gain the knowledge about the formulation of sourdoughs for the production of high quality bread. Together with the partner an Austrian sourdough database will be set up that will be used by the project partner to help Austrian backeries to improve the quality of their products.

Microorganisms can enter the process of sugar production through different ways and can lead to economically significant sugar losses, whereas extraction area and juice purification are the most important process steps. Due to the high temperatures, especially thermophilic bacteria play a role in these production steps as they use sucrose and lead to direct losses of sugar. The acidic metabolites formed by these bacteria reduce the pH-value, resulting in hydrolytic cleavage of sucrose and indirect sugar losses as well. As part of this work, the influence of different technologies in sugar factories of AGRANA on occurring MOs should be examined in order to establish new models for optimizing operating procedures based on the results. Consequently, existing disinfection procedures should be refined on the one hand and on the other hand new methods should be evaluated in order to minimize sugar losses caused by Microorganisms.
