In Escherichia coli and some other coliforms, lysine decarboxylase is encoded by cadA which participates in the decarboxylation of lysine and synthesis of cadaverine [30].
The strain was unusual because it was negative for the production of lysine decarboxylase and b-galactosidase (ortho-nitrophenol test) and positive only for stx1.
