Research description

In current biotechnology practice screening of microbes is performed in batch mode, while most industrial reactors operate in fed-batch mode. It is well established that the performance of these microbes in nutrient rich environments (batch) differs from the performance in nutrient poor environments (fed-batch), explaining the limited success in microbe development. This project aims at development of a Lab on a chip platform for performing high throughput screening of microorganisms under industrially relevant conditions. In contrast to the conventional batch screening which leads to mutants failing to generate yields at an industrial scale, we want to use droplet microfluidics for screening the mutants in fed batch mode. By doing so, we wish to provide the same physiological environment to microbes during screening as it would have during the growth in the industrial fermentor. After developing such screening device we aspire to study the effect of different nutrient feed profiles on growth rate of microbes, nutrient consumption rates and yields of the desired metabolites. Eventually this technology would be validated by screening a well characterized yeast strain with it, thereby ensuring a quick adoption of this device by industry.
