The main idea of MIX-UP (MIXed plastics biodegradation and UPcycling using microbial communities) is to showcase a novel approach for plastic recycling and therefore addresses one of the greatest challenges of our time: the establishment of a circular (bio)-economy for plastics. The continuing demand for plastic products, the lack of appropriate recycling and the ubiquitous pollution of the environment with plastic waste pose a global challenge. An ambitious vision and considerable efforts are ...

The aim of the project is bioprospecting, isolation and characterization of novel secondary metabolites, produced by extremophilic microorganisms. The project is dedicated to a poorly investigated problem of antagonistic interactions between extremophilic microorganisms in their communities, namely, to the investigation of the ability of extremophiles to produce secondary metabolites with biocidic, cytotoxic and cytostatic activities. Working out this problem will fulfill an important applied ...

Public showcase and collection of training material

The workshop focuses on the publication, curation, retrieval, and usage of kinetic data from the reaction kinetics database SABIO-RK and on the use of data in modeling. There will be experience reports from scientists who successfully used experimental data to formulate or verify biological hypotheses with the computer, and you will experience how experimental data can be used with computational models.

ZucAt - Sucrose (from german Zucker) translocation in Arabidopsis thaliana. Sucrose translocation between plant tissues is crucial for growth, development and reproduction of plants. Systemic analysis of this metabolic process and underlying regulatory processes can help to achieve better understanding of carbon distribution within the plant and the formation of phenotypic traits. Sucrose translocation from ‘source’ tissues (e.g. mesophyll) to ‘sink’ tissues (e.g. root) is tightly bound to the ...

Research in Systems Biology involves integrating data and knowledge about the dynamic processes in biological systems in order to understand and model them. By connecting fields such as genomics, proteomics, bioinformatics, mathematics, cell biology, genetics, mathematics, engineering and computer sciences, Systems Biology enables discovery of yet unknown principles underlying the functioning of living cells. At the same time, testable and predictive models of complex cellular pathways and ...

Sucrose translocation from ‘source’ tissues (e.g. mesophyll) to ‘sink’ tissues (e.g. root) is tightly bound to the proton gradient across the membranes. The plant sucrose transporters are grouped ...

Experimental study for hands on session

Motivated by an increasing population and the desire to grow plants more efficiently, attention has turned to the use of Light Emitting Diodes (LEDs) to illuminate plants which are grown indoors. Indoor growing facilities enable closely controlled and mon- itored environmental conditions. More and more of these facilities exchange High Pressure Sodium (HPS) lamps for LED lighting since they provide more efficient lighting and the possibility to control light intensity and quality in order to ...

we describe a multi-compartmental model consisting of a mesophyll cell with plastid and mitochondrion, a phloem cell, as well as a root cell with mitochondrion. In this model, the phloem was considered as a non-growing transport compartment, the mesophyll compartment was considered as both autotrophic (growing on CO2 under light) and heterotrophic (growing on starch in darkness), and the root was always considered as heterotrophic tissue completely dependent on sucrose supply from the mesophyll ...

The multi-compartmental metabolic network of Arabidopsis thaliana was reconstructed and optimized in order to explain growth stoichiometry of the plant both in light and in dark conditions. Balances and turnover of energy (ATP/ADP) and redox (NAD(P)H/NAD(P)) metabolites as well as proton in different compartments were estimated. The model showed that in light conditions, the plastid ATP balance depended on the relationship between fluxes through photorespiration and photosynthesis including both ...

The solution of Flux Balance Analysis (FBA) represents metabolic flux distribution in ZucAt model under light growth conditions. In this solution, (i) the ratio photorespiration / photosynthesis has been fixed to 0.25; and (ii) cyclic electron flow through FQR (ferredoxin-plastoquinone reductase) has been set 0.1 from non-cyclic flow through FRN (ferredoxin-NADP oxidoreductase). Under this constraints, ATP formed by non-cyclic photophosphorylation is not sufficient to fulfill ATP/NADPH ratio for ...

The solution of Flux Balance Analysis (FBA) represents metabolic flux distribution in the model under light growth conditions. In this solution, (i) the photorespiration was set to 0; and (ii) cyclic electron flow through FQR (ferredoxin-plastoquinone reductase) has been set of 0.1 of flow through FRN (ferredoxin-NADP oxidoreductase). Under this constraints, ATP is under-produced in plastid and therefore is additionally imported to cytoplasm. Flux through FQR represents cyclic electron flow through ...

In this solution, (i) the ratio photorespiration / photosynthesis has been fixed to 0.25; and (ii) cyclic electron flow through FQR (ferredoxin-plastoquinone reductase) has been set 0.5 from non-cyclic flow through FRN (ferredoxin-NADP oxidoreductase).

The solution of Flux Balance Analysis (FBA) represents metabolic flux distribution in ZucAt model under light growth conditions. In this solution, (i) the ratio photorespiration / photosynthesis has been fixed to 0.25; (ii) and ATP transport between plastid and cytoplasm has been set to 0. The last constraint allows finding the ratio between fluxes through FQR (ferredoxin-plastoquinone reductase) and FRN (ferredoxin-NADP oxidoreductase) under which the ATP balance in plastid becomes self-sufficient ...
