DOI: 10.1007/s00216-020-02677-7
Abstract: Diamino-oxidase (DAO), horseradish peroxidase (HRP), and tetramethylbenzidine (TMB) have been immobilized into cellulose to obtain circular cellulose test supports (CCTSs) for the determination of cadaverine (Cad) and putrescine (Put). During the enzymatic reaction, TMB is… read more here.

DOI: 10.1016/j.bej.2020.107514
Abstract: Abstract Cadaverine, also known as 1,5-diaminopentane, is a biogenic amine particularly used for the synthesis of nylon. Cadaverine can be efficiently synthesized through decarboxylation of lysine in microorganisms. However, the respective metabolic pathways in Escherichia… read more here.
