Several recent studies have highlighted the inhibitory effects different plant hydrolysate compounds have on the conversion of plant cellulose to biofuels. These compounds include phenolic acids and aldehydes as well as furans. In this talk, I will discuss research out group has performed to (1) Select biomarker genes from E. coli that are responsive to these compounds; (2) Clone the promoters regulating expression of these genes to generate transcriptional fusions with the bioluminescence genes; (3) Characterize the responses from bioluminescent strains of E. coli to a wide number if chemical effectors and actual rice straw hydrolysates. The results show that we can detect these compounds, including ferulic acid, vanillin and furfural, at concentrations below their published inhibitory concentrations, making these strains a quick and effective tool to assess for these and other chemical effectors within biomass hydrolysates samples.
