Working Group Microbiology
Leader Privatdoz. Mag.rer.nat. Dr.rer.nat. Irina Druzhinina (habilitated in microbiology)
The group of Microbiology (initially as the project group Fungal Evolution and Biodiversity) was established in 2002, when the first application of molecular biology methods highlighted the urgent need for the study of microbial biodiversity. Since then, our research has focused on the diversity and evolution of filamentous fungi on the molecular level and on the development of the modern bioinformatic tools for their correct identification.
We are deeply interested in understanding the speciation process in mitosporic filamentous fungi and in the development of integrated DNA-based and metabolic species criteria that could be applied to the differentiation of these organisms. The main model organisms for our research are cosmopolitan fungi from the order Hypocreales; the mycoparasitic genus Hypocrea, including its mitosporic derivate Trichoderma and the plant pathogenic fungus Gibberella (mitosporic form Fusarium).
DNA BARCODING
We are interested in whole genus screening for the most appropriate biotechnological agents because Trichoderma is an important industrial microorganism used in the production of extracellular enzymes and in agriculture as agents of biological control of plant pathogenic fungi. For this purpose, we constantly work on the development of multigene molecular DNA barcode methods for quick in silico identification of Hypocrea and Trichoderma.
ECOLOGICAL GENOMICS
Currently we are the most challenge by the comparative genomics of filamentous fungi as the first three genomes of Trichoderma species have been released to the publics and our group is deeply involved in the sequencing of the additional 4 species of Trichoderma. We are interested in the revealing the ecological genomics of Trichoderma when we aim to understand the biology of this industrially important microorganisms through the function and evolution of its genomes.
MYCOPARASISM
We are also interested in Trichoderma mycoparasism as a genus-wide trait of the fungus and in the screening various indigenous ecosystems for the best mycoparasitic strains of Trichoderma that can be locally applied for protection of such crops as coffee, cacao or banana. The recent results showed that Trichoderma may be used in arid agriculture as it contains halotolerant isolates. The project is of particular importance for Middle East and North Africa.
METAGENOMICS
In addition to molecular diversity and evolution, we are interested in the in situ ecology of these organisms and their nutritional preferences and interactions with other microbionts in their ecosystem. For this reason, we direct our research towards the introduction of modern metagenomic and metatranscriptomic methods.
PHENOTYPE PROFILING
The other focus of our research is the functional biodiversity of filamentous fungi. We developed semi-high-throughput methods of phenotype profiling to study the response of fungi to various abiotic factors (illumination, temperature, carbon and nitrogen nutrition) and their interactions with other microorganisms in the environment.
HYDROPHOBINS
The new branch of our research is the screening for novel Trichoderma hydrophobins, the small cystein-rich proteins, which have a potential of targeting enzymes to polymers. This project is developed in collaboration with Austrian Center of Industrial Biotechnology (ACIB) and university of Graz (Austria).
