Molecular Microbiology Definition Molecular microbiology is the branch of microbiology devoted to the study of the molecular basis of the physiological processes that occur in microorganisms study of the formation, structure, and function of macromolecules essential to life the manipulation of DNA

Molecular Microbiology Methods • Sample preparation – DNA extraction RNA extraction c. DNA – PCR • Band patterns – – Multiplex PCR RT-PCR (Reverse Tramscription/Real Time) PFGE RAPD AFLP DGGE Restriction • Hybridisation – – Probes Southern/Northern blots Microarrays DNA melting – RT-PCR product validation %GC DNA: DNA similarity • Sequencing – Sanger sequencing – NGS – Next/New Generation Sequencing

Expertise • Application of data analysis methods, including linear and non-linear multivariate statistics and neural networks – to microbial systematics, the classification and identification of micro-organisms; – search and discovery of novel organisms for screening and the development of bio-active compounds; – marine microbial ecology – process control and optimization of fermentation processes, both for research and development and in large scale industrial application. • My personal research themes are: – bioinformatics and bacterial taxonomy • • identification of microbes, molecular identification comparative genomics and expression data analysis MALDI mass spectrometry and chemical fingerprinting data analysis and poly-phasic taxonomy – Bioprocess modelling, supervision and control
