A number of lysine‐auxotrophic mutants of Pseudomonas aeruginosa PAOl were isolated through mutagenesis by means of N‐methyl‐N‐nitrosoguanidin (Mach et al. , unpublished). Using the cross feeding test and growth tests classification of lysine mutants was not possible. The investigation of diaminopimelic acid decarboxylase (DAP‐DC) showed, that none of these mutants had an active enzyme, except for the mutants with a high number of revertants. The appearance of only one mutant type is attributed to the insufficient availability of DAP.
