Popular views classify microbes either as a good or bad guys, however these phenomenon imply very complex processes in reality. It is no exaggeration to say that to understand host-microbe-environment interactions at the level of biological complexity is one of the greatest challenges in biology. Recently genomics, proteomics, high-throughput microarray and next-generation sequencing (NGS) technologies have extended our ability to provide new insight into the molecular basis of these fundamental questions.

As the problem of antimicrobial resistance becomes more widespread, the need for new anti-infective agents is more urgent than ever. As a part of these efforts, massively parallel NGS technologies provide a tremendous ability to typify microbes, not only on the basis of readily observable characteristics, but also upon their genetic (biosynthetic) potential.

In respect of the clinical needs, on the bases of our ongoing microbial whole genome shotgun sequencing (WGS) project, we designed strategy and workflow to isolate new microbial natural products (e.g. antimicrobials) and screening for potential producing microorganisms. It is important to highlight the fact that the lack of genome sequence information in non-model species often limits the downstream scientific activities, such as engineering microbial metabolic pathways. We hope that our structural genomics efforts will form a foundation for the subsequent research steps, like intelligent drug design, identification of new pathogenicity factors and target discovery etc.

State of art genomics approaches provides revolutionary tools with numerous applications, which can address different questions in almost all aspects of biological research. Nevertheless, one of the major challenges biologists are facing today is to understand and be able to interpret the functional complement (transcriptome, proteome) of the genome, which is a dynamic link between genotype and complex phenotype. Based on the assumption of one technology being able to standalone does not suffice for gaining a comprehensive understanding of any complex biological process. Therefore we intend to use complementary approaches i.e. transcriptomics (RNA-seq, microarray) and proteomics (2D PAGE) for developing molecular diagnostic methods to identify drug-, toxicant- and disease-related biomarkers.

Due to the broad range of microbial model systems formally used, and extensive research experience in the fields of traditional and molecular-microbiology, the Microbial Biotechnology Group is ready to face challenges in health, industry and agriculture sectors of biotechnology.
