Abstract
A novel plasmid pCX311, which was constructed from Bacillus sp. C125 chromosomal DNA carrying the gene for extracellular production of xylanase and a vector plasmid pBR322. A novel microorganism, Escherichia coli HB101 (pCX311) carrying the plasmid pCX311 and being capable of extracellular production of xylanase. Method for culturing the microorganism characterized by cultivation of it in the medium containing NaCl (or KCl) and bran, or NaCl (or KCl) and xylan for 12-48 hours. According to this invention, useful high-molecular substances can be produced in a high yield.
