Module 2: metabolic engineering
In this module you will use a modified Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR) system to modulate transcription in E. coli. Specifically, you will use a CRISPR-based interference system to target a gene within the fermentation pathway of E. coli such that either ethanol or acetate production is increased.
Research goal: Increase the yield of commercially valuable byproducts in E.coli using CRIPSRi technology to target genes involved in mixed-acid fermentation pathway.
