Eunice won the LABIP poster award for excellent research with industrial relevance

At the13th international symposium on lactic acid bacteria Eunice van Pelt – KleinJan, PhD student in Bas Teusink’s group, won the LABIP poster award for excellent research with industrial relevance. The poster “Proteome constraints shape Lactococcus lactis’ metabolic behaviour” shows that we can understand the changes and choices in energy metabolism that Lactococcus lactis (needed a.o. for Gouda cheese) makes,

Publication by Chrats: High biodiversity in a benzene-degrading nitrate-reducing culture is sustained by a few primary consumers.

A key question in microbial ecology is what the driving forces behind the persistence of large biodiversity in natural environments are. We studied a microbial community with more than 100 different types of species which evolved in a 15-years old bioreactor with benzene as the main carbon and energy source and nitrate as the electron

Article published by Paul : Effects of DNA preservation solution and DNA extraction methods on microbial community profiling of soil

Abstract Microbial community profiling using high-throughput sequencing relies in part on the preservation of the DNA and the effectiveness of the DNA extraction method. This study aimed at understanding to what extent these parameters affect the profiling. We obtained samples treated with and without a preservation solution. Also, we compared DNA extraction kits from Qiagen

Nature review article by Evelina : Intracellular mRNA transport and localized translation.

Abstract Fine-tuning cellular physiology in response to intracellular and environmental cues requires precise temporal and spatial control of gene expression. High-resolution imaging technologies to detect mRNAs and their translation state have revealed that all living organisms localize mRNAs in subcellular compartments and create translation hotspots, enabling cells to tune gene expression locally. Therefore, mRNA localization

We reviewed more than a decade of research on the search for principles of microbial physiology

When Bas Teusink and Douwe Molenaar came to the VU University, about a decade ago, they had just published a thought-provoking paper on how microbial physiology can result from optimal allocation of biosynthetic resources, such as ribosomes, RNA polymerases, amino acids, energy, etc., in order to maximise growth rate (https://doi.org/10.1038/msb.2009.82). Roughly at the same time,

SBML Level 3: the standard for encoding models of biological processes

Brett and Bas are co-authors on a new paper in Molecular Systems Biology describing the latest developments in model encoding in systems biology. Bas enthusiastically supports the use of standards in systems biology while Brett has been active in the SBML field for 15 years as a community member, specification writer, package coordinator (FBC), libSBML

Paper by Niclas, Johan and Frank

Biphasic Cell-Size and Growth-Rate Homeostasis by Single Bacillus subtilis Cells Abstract The growth rate of single bacterial cells is continuously disturbed by random fluctuations in biosynthesis rates and by deterministic cell-cycle events, such as division, genome duplication, and septum formation. It is not understood whether, and how, bacteria reject these growth-rate disturbances. Here, we quantified
