Then D-α-amino-ε-caprolactam and pyridoxal-5-phosphate were added to the disintegrated cell suspensions of each monoculture to concentrations of 5 g/l and 0.01 mM respectively. After 1.5 h of incubation at 20° C. and 20 rpm, 2 ml samples were transferred into 1 ml of 1 M H3PO4. After removal of all particulates by centrifugation followed by filtration through a 0.22 μM filter, concentrations D- and L-α-amino-ε-caprolactam in the samples were determined by HPLC using the protocol as described in Example 1. Finally, monocultures that formed L-α-amino-ε-caprolactam from the D-α-amino-ε-caprolactam substrate were sent to the NCIMB for strain determination.
