1. Tryptophan as a real-time indicator of e.coli

2. Optical Brighteners as an indicator of source

New Tools = New Opportunities

1. Tryptophan as an indicator of e.coli

• Tryptophan is an amino acid used in synthesis of proteins.

• Tryptophan and bacteria cell walls have the same UV absorption spectrum.

• Makes it easy to measure.• Measuring tryptophan can be used a

surrogate indicator for e.coli.
