Computer-Controlled Cyborg Yeast

Posted by samzenpus on from the all-your-bread-are-belong-to-us dept.

MrSeb writes "With a slightly weird world first, scientists have formed a feedback loop between common, baking and brewing yeast, and a computer. The computer can trigger the yeast to produce a protein, and the yeast then feeds back to the computer how much of the protein is being produced — the computer has exact control over the yeast's production. This work, performed by scientists at the Automatic Control Laboratory at the Swiss Federal Institute of Technology Zurich, is exceptional because of its simplicity: The computer turns the yeast on by flashing a red light, and it turns the yeast off by flashing a deeper red light. Connected to the yeast is a 'reporter' molecule that fluoresces when the protein is produced. The computer can see this fluorescence and alter the light it emits, thus creating a full feedback loop. The simplicity is significant because of the role of yeasts and bacteria in the production of antibiotics, biofuels, and more. The problem is controlling those organisms — so far, scientists have tried to genetically add synthetic control circuits, with limited success... and now the Swiss have shown that it can be done by simply shining a couple of lights."

    A minor clarification to TFS: "The problem is controlling those organisms — so far, scientists have tried to genetically add synthetic control circuits, with limited success... and now the Swiss have shown that it can be done by simply shining a couple of lights."
     
    The control circuit genes still have to be added synthetically (or at least added in conjunction with a suitable promoter sequence (in this case, Gal1 which has a binding site for Gal4 - part of the fusion construct responsible for the light activation). The fact is that there are several well documented transcription control mechanisms (lac operon, trp operon, arabinose promoter etc) that are currently used at the industrial scale for microbes. The lights are new, but since the reporter gene in this case (YFP) was being read using flow cytometry, this is very unlikely to be cheaper or easier to work with. Most of us will stick with good old IPTG for inducing gene expression in our microbes.
