NEB 10-beta E. coli, which lack the native fim switch (fimS) and known fim recombinases, were co-transformed with K1077007(amilCP j23100 fim switch) or K1077003(GFP j23100 fim switch), and K1077002 (aTc inducible fimE, HSL inducible hbiF) and plated on to LB plates with or without inducer.

Fig 2. - An inducible fim transcriptor system changes states and produces protein output

NEB 10-beta E. coli, which lack the native fim switch (fimS) and known fim recombinases, were co-transformed with K1077007(amilCP j23100 fim switch) or K1077003(GFP j23100 fim switch), and K1077002 (aTc inducible fimE, HSL inducible hbiF) and plated on to LB plates with or without inducer. A) Close up of 3 colonies on a plate containing K1077007 and K1077002 co transformants. Three distinct phenotypes were observed: Solid Blue colonies(bottom left), Mixed colonies that had distinct white and blue regions(bottom middle), and Solid White colonies(top right). Therefore, the uninduced fim transcriptor in the context of K1077002 is subject to leaky fimE and/or hbiF activity. B) Quantification of the phenotypes observed on the plate in A. C) When induced with 4.32µM aTc and grown overnight (left) , no GFP is produced as expected due to induced fimE turning the switch OFF. When induced with 1µM HSL and grown overnight (right), GFP is produced as expected due to induced hbiF turning the switch ON.
