Culture profiles of the pduL2::IPA strain when supplemented with gaseous substrates, CO (A) or syngas (CO:H₂ = 1:1) (B). Products including acetate, acetone, formate, and IPA, in the culture supernatant were measured at each time point. Dry cell weight was calculated according to the OD. Data are presented as the mean with SDs of three biological replicates
