A lambda recombinant phage expressing beta-mannanase activity in Escherichia coli has been isolated from a genomic library of the extremely thermophilic anaerobe "Caldocellum saccharolyticum." The gene was cloned into pBR322 on a 5-kb BamHI fragment, and its location was obtained by deletion
Commercially available enzymes do not contain all the necessary softwood-specific accessory enzymes to obtain high saccharification efficiency. In this work, six saprophytic fungi obtained from Pinus radiata plantation site were screened for the putative softwood-specific accessory enzyme,
Genomic walking PCR was used to obtained a 4,567-bp nucleotide sequence from Caldibacillus cellulovorans. Analysis of this sequence revealed that there were three open reading frames, designated ORF1, ORF2, and ORF3. Incomplete ORF1 encoded a putative C-terminal cellulose-binding domain (CBD)
