Konstantinos Kormas received his BSc (1994) and PhD (1998) from the Biology Department of the University of Athens, Greece. He worked as a Post-doctoral fellow at the Trondhjem Biological Station, Norway and Woods Hole Oceanographic Institution, USA. Since 2015, he is a Professor of Aquatic Microbial Ecology at the University of Thessaly, Greece. His research focuses on the patterns and processes that underpin the distribution and abundance of microorganisms in different habitats of the aquatic environment, including plankton, benthos and symbionts. He has published more than 80 papers in peer-reviewed journals.


Bacteria are the main symbionts of the gastrointestinal tract (GIT) of practically every macro-organism that has been studied so far. Usually the benefits of this symbiosis are far more significant than the harmful (pathogenic/toxic) symbiotic relations occurring in some animals. Of all the GIT-bacteria systems known to date, aquatic animals are among the least studied. The GIT of commercially reared fish, consist an excellent ecosystem for the investigation of the origin, establishment and growth of their bacteria populations. The major reason for this is that the GIT of reared fish: (1) receives a relatively constant food supply of specific ingredients, serving as the growth medium of the symbiotic bacteria; (2) is characterized by a rather constant suite of in situ environmental conditions, which set a stable and known profile of incubation conditions of the symbiotic bacteria; and (3) aquaculture installations come in various systems and can be found in a wide array of locations around the world covering both freshwater, brackish and marine habitats. Available studies to date, depict that: various reared fish species harbor different but specific prokaryotic communities, being shaped by the supplied diet and/or the animal’s habitat; have temporally variable symbiotic bacterial communities; populations of reared species have distinct GIT bacterial communities compared to their wild counterparts; there is uncertainty on the fish GIT bacteria origin; and the understudied effect of the individual variability vs. individual independent, limits us from depicting a true core microbiome for species of reared fish.

Susanne Zeilinger has studied Microbiology and Genetics from the University of Vienna and during her Diploma thesis she gained experience in fungal enzyme characterization from the VTT Technical Research Center of Finland. She did her PhD from the Technical University of Vienna (TUW) on fungal cellulase gene regulation. As a Post-doctorate she has worked on Trichoderma biocontrol at TUW and as a Visiting Scientist at the Institute of Plant Pathology in Portici, Naples, Italy. In 2003, she became the Group Leader in the Research Area of Biotechnology and Microbiology at the Institute of Chemical Engineering at TUW. Since 2015, she is a Full Professor for Microbiology at the University of Innsbruck, Austria. Her research focuses on molecular fungal biology with a special interest in interactions of fungi with other (micro-) organisms, bio-communication and signal transduction.


Mycoparasitic species of the fungal genus Trichoderma are among the most successful bio-fungicides in today’s agriculture although our understanding of the exact molecular mechanisms of their activity still is fragmentary. The biological control of fungal plant diseases by Trichoderma includes direct antagonism of phytopathogenic fungi by mycoparasitism. This mycoparasitic attack comprises sensing of the prey and chemotropic growth towards it followed by overgrowing and killing of the prey fungus. Genome sequence analysis of Trichoderma mycoparasites showed an abundance of cell wall lytic enzymes such as chitinases and glucanases essential for prey lysis and degradation and an assortment of genes involved in the formation of secondary metabolites for chemical warfare. The signals activating the mycoparasitic response include surface molecules and surface properties and may also include prey-derived secondary metabolites and other small substances exchanged between the interaction partners. Investigations of Trichoderma atroviride will be presented showing that this potent mycoparasite relies on G protein and MAP kinase signaling for triggering of the mycoparasitic response. Results on the role of the Gpr1 7-transmembrane receptor in the recognition of prey-derived signals will be shown as well as data on transcriptome profiling of gpr1-mutants and mutants interrupted in Tmk1 MAP kinase signaling.

Raimondas Jasevičius has completed his PhD from Vilnius Gediminas Technical University (VGTU) and Post-doctoral studies from Vilnius University, Lithuania. He is a Senior Researcher, Institute of Mechanics and is an Associate Professor, Department of Printing Machines, VGTU. He has built an adhesive dissipative interaction model after years of experience in research with Otto von Guericke University and Berlin Technical University, Germany. He has more than 18 published articles in reputed journals.


The behavior of non-biological spherical particles can be readily modeled with the discrete element method. The size of the particles thereby plays an important role in particle or particle system behavior. For micron-sized particles the attractive force becomes dominant, thus specific knowledge is needed regarding it. This knowledge can be applied not only for nonbiological, but also for biological similar sized objects, such as cells. This can extend the implementation, the understanding and possible applications of the discrete element method even up to the molecular dynamics level. In this work, we introduce models for cell interaction, basing on experience from modeling the interaction of ultrafine particles. The cell is thereby considered as a colloid particle, where an idealization with continuum mechanics is applicable. The model parameters for
the cells are taken from known physical experiments performed with spherical S. aureus bacteria. The presented model is universal, and can be applied for the modeling of the dynamics of possibly other cell types as well. The investigation of the dynamics of a single bacterium may help to understand the behavior of a system of bacteria (e.g. biofilm formation) as well as the transmission of infections in the air. One of the important factors influencing the stability of a bacterial structure, but also important in the context of an infection is the adhesion force. Detailed results on the sticking process of a bacterium are presented. A characterization of the influence of repulsive and attractive forces on the bacterium is given. The obtained results are shown in terms of force displacement diagrams as well as a function of the interaction and sticking time history. For the modeling of the system behavior the sticking process of 10,000 bacteria is considered.
