Cloning and expression of the hydrogenase gene fromClostridium butyricuminEscherichia coli

Abstract
Hydrogenase gene from Clostridium butyricum was cloned in Escherichia coli HK16 (Hyd) using pBR322 and PstI. The plasmid, pCBH1, containing hydrogenase gene was 7.3 MDa and pCBH1 had 5 PstI-DNA fragments (3.9, 2.6, 0.7, 0.03–0.04, C. butyricum and E. coli C600 (Hyd+).
