A cellulase gene of Clostridium themocellum was transferred to Escherichia coli by molecular cloning with pBR322. The gene was carried in a Hind III digested DNA sequence of about 1.8 kb. This Rind III fragment expressed activities on carboxymethyl cellulose (CMC) and on filter gaper in E. coli. The expression of clostridial cellulase gene in E. coli was studied and compared with the pro-ducts of cellulase genes in C. themocellum.
