OptSwap optimizes microbial strain design for production-scale bioprocessing

18.09.2013
Using a new in silico method called OptSwap scientists can predict how to engineer microorganisms to increase the yield of high-value biobased chemicals produced by industrial-scale cell factories.

This example of how advanced computational tools are being applied to genome-scale metabolic modeling in microbes illustrates the important contributions from the field of Systems Biology, as highlighted in a special research section in Industrial Biotechnology, a peer-reviewed journal from Mary Ann Liebert Inc., publisher. The articles are available on the Industrial Biotechnology website.

The article "Optimizing Cofactor Specificity of Oxidoreductase Enzymes for the Generation of Microbial Production Strains—OptSwap," by Zachary King and Adam Feist, University of California, San Diego and Technical University of Denmark, Lyngby, describes the development of OptSwap. The authors identified microbial strain designs with significant advantages for the production of L-alanine, succinate, acetate, and D-lactate under the modeled conditions.

"The OptSwap method of King and Feist provides a great example of how systems approaches can enable more effective design and simulation of microbial strains," says Guest Editor Nathan D. Price, PhD, Associate Director, Institute of Systems Biology (Seattle, WA) and a member of the Industrial Biotechnology Editorial Board.

The IB IN DEPTH special section on Systems Biology includes review articles by Kieran Smallbone (University of Manchester, UK) and Pedro Mendes (Virginia Tech, Blacksburg): "Large-Scale Metabolic Models: From Reconstruction to Differential Equations"; Jacob Koskimaki, Anna Blazier, Andres Clarens, and Jason Papin (University of Virginia, Charlottesville): "Computational Models of Algae Metabolism for Industrial Applications"; Scott Harrison and Markus Herrgård (Technical University of Denmark, Hørsholm): "The Uses and Future Prospects of Metabolomics and Targeted Metabolite Profiling in Cell Factory Development"; and Manual Alberto Garcia-Albornoz and Jens Nielsen (Chalmers University of Technology, Göteborg, Sweden): "Application of Genome-Scale Metabolic Models in Metabolic Engineering."

Research articles by Hnin Aung, Susan Henry, and Larry Walker (Cornell University, Ithaca, NY): "Revising the Representation of Fatty Acid, Glycerolipid, and Glycerophospholipid Metabolism in the Consensus Model of Yeast Metabolism,"; and by Patrick Hyland and Radhakrishnan Mahadevan (University of Toronto, Canada) and Serene Lock-Sow Mun (Universiti Teknologi Petronas, Tronoh Malaysia): "Prediction of Weak Acid Toxicity in Saccharomyces cerevisiae Using Genome-Scale Metabolic Models" round out the special section.

About the Journal

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
