Figure 4From: The analysis of para-cresol production and tolerance in Clostridium difficile 027 and 012 strainsAnalysis of the decarboxylase mutants. A) NMR spectra showing p-cresol production in BHI broth supplemented with 0.1% p-HPA for parent and mutant strains, B) Growth curve of the R20291ΔhpdC and 630ΔhpdC mutants compared to respective parent strains. C) Tolerance to 0.1% p-cresol of ΔhpdC mutants and respective parent strains.Back to article page
