sRNAs are gene regulators in bacteria. Here, we developed synthetic sRNA gene knockdown technique. Synthetic sRNA properly repressed DsRed2. Synthetic sRNAs was used to enhance the production of tyrosine and cadaverine. Through screening of 14 strains with sRNAs, we isolated a strain producing 2 g per liter of tyrosine. Using a library of 130 synthetic sRNAs, murE was isolated which shows 55% increase in cadaverine production.
