Evaluation of caprolactam degradation in resting cells assays (DOλ600nm ≈ 6), by E. coli BL21(DE3) strain carrying either pET-30b( +), pET-chnC or pET-hyuA/B over a 24 h incubation period in 50 mM of phosphate buffer (pH 7.2) and 3 mM caprolactam. Values are means ± SE (n = 3, for all biological assays). AB—abiotic control.
