OAH activity, growth and pH profiles of Pf13525 wild type and genetically modified strains.

(A) OAH activity in M9 minimal medium. Results are given as mean ± SD of three independent observations. Values are compared with Pf(pKCN2), **, P < 0.0067; ns, non-significant; (B) Growth profile and (C) pH profile in TRP minimal medium containing 100 mM glucose as carbon source. O.D.600nm and pH values at each time point are represented as the mean ± SD of four to six independent observations.
