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.
