|This year, the Synthetic BiOWLogists are focusing on two new projects. The first project is the creation of BioBeer by incorporation of the resveratrol biosynthetic pathway into the Saccharomyces cerevisiae genome. Resveratrol production during fermentation will be quantified and compared with natural resveratrol sources. The second project is the construction of a novel virus mediated signal amplification system. The initial focus of this project will be to detect and report the presence of an extremely small proportion of a target genotype in a mixed population.

Cell number and cell type detection is an important area of active interest. Both in cancer detection and monitoring circuit stability, the ability to quantify a small proportion of deviant cells is critical to understand the population mechanics. The ability to distinguish between genotypes will allow researchers to better understand how organisms lose engineered circuits without a selective pressure and allow for earlier treatment of precancerous tumors. Additionally, detection  of the presence of unique genotypes in an initially homogeneous population allows for contamination alert.

This year, the Synthetic BiOWLogists are focusing on BioBeer!!! The creation of BioBeer entails the incorporation of the resveratrol biosynthetic pathway into the Saccharomyces cerevisiae genome. Resveratrol production during fermentation will be quantified and compared with natural resveratrol sources.

Concept

Resveratrol.JPG

Resveratrol is an unique phytoalexin produced by grapes, peanuts, and knotweed that has known and putative physiological effects. In mice, resveratrol has been linked to anti-inflammatory, anti-cancer, and cardiovascular benefits. Resveratrol has been reported to significantly extend the lifespan of the Saccharomyces cerevisiae. Additionally, resveratrol has been hypothesized to account for the French Paradox.

Using an engineered biosynthetic pathway in Saccharomyces cerevisiae, this project will attempt to create marmite and beer. A proprietary hefeweizen strain was obtained from St. Arnold's [1]. This industrial strain is a putative diploid/polyploid strain that is used for fermentation of unfiltered beer.
