Colonic Acid Quantification
Background
Colonic Acid is a polysaccharide containing a repeat unit with D-glucose, L-fucose, D-galactose, and D-glucuronate. Biological extracts often contain compounds, which under heating with H2SO4 yield brown products absorbing between 396 nm and 427 nm. Colonic acid can be estimated by measuring L-fucose content.

Timed Lysis: Inducible/Repressible Promoter
gadAp: A pH Sensitive Promoter
Based on available literature (cite), we expected an increase in expression from gadAp (BBa_K318512) under both acidic pH conditions (from pH 5 to 3) and in the stationary phase (after an OD of 1 or 2). In order to test this, we combined the gadA promoter with a RFP gene (BBa_K318513). This part
