Putresina diproduksi pada skala industri nelalui [[hidrogenasi]] [[suksinonitril]], yang dihasilkan dengan penambahan [[hidrogen sianida]] ke [[akrilonitril]].<ref name=Ullmann>{{cite encyclopedia

Biotechnological production of putrescine from renewable feedstock is a promising alternative to the chemical synthesis. A metabolically engineered strain of ''[[Escherichia coli]]'' that produces putrescine at high titer in glucose mineral salts medium has been described.<ref name="Metabolic Engineering of Escherichia coli for the Production of Putrescine: A Four Carbon Diamine">{{cite web
