Intake of cruciferous vegetables (e.g. broccoli and cabbages) characteristic with their content of glucosinolates, is associated with numerous health benefits including reduced risk of developing cancer. Substantial attention has been given to the glucosinolate glucoraphanin that is highly enriched in broccoli and associated with its health-promoting properties. However, we need to eat ~1 kg of broccoli pr. week to get the health benefits of broccoli. This has primed a desire to engineer microbial production of glucosinolates as dietary supplements.
Your task (can be adjusted dependent on interest)
Our goal is to engineer the health-promoting, bioactive glucosinolates from cruciferous vegetables into microbial cell factories. We are building a platform for efficient production by application of advanced synthetic biology. We currently focus on the following projects:
1) Establishment of Crispr-based genome integration
2) Boosting the levels of precursors and co-factors
3) ‘Omics-based strain optimization to increase flux through the pathway
4) Transport engineering to ensure efficient flux through the pathway and efficient export to increase yield, prevent feedback inhibition and reduce toxicity
