Abstract
Abstract DNA fragments containing an alkaline cellulase K gene, which comprise about 4.0, about 2.4 and about l.9 kilo base pairs, respectively, each having a specific restriction map, recombinant plasmids containing any of these DNA fragments, and recombinant microorganisms harboring any of said plasmids. The alkaline cellulase K gene is derived from a bacterial strain which belongs to the genus Bacillus and is alkalophilic, that is, capable of revealing an optimum growth in an alkaline pH region.
