Abstract
An endoglucanase chromosomal gene from the cellulolyticPseudomonas fluorescens var.cellulosa (NCIB 10462) was cloned inEscherichia coli. Chromosomal DNA was partially digested with the restriction enzymeEcoRI and ligated into the broad host-range, mobilizable plasmid pSUP104 that had been linearized with the same enzyme. After transformation ofEscherichia coli, and endoglucanase-positive clone was detected in situ by use of the Congo-red assay procedure. The endoglucanase gene on the recombinant plasmid pRUCL 100 was expressed in the non-cellulolyticPseudomonas fluorescens PF41. The DNA fragment carrying the gene was transferred to the plasmid pBR322, generating plasmids pRUCL150 and pRUCL151, and its restriction map was derived.Keywords
