Abstract
A novel .beta.-amylase gene is provided. This gene is useful for production of a thermophilic .beta.-amylase obtained from Clostridium thermosulfurogenes on a large scale, especially from genetically engineered microorganisms introduced with this gene. B. subtilis was transformed with a plasmid pNK1 containing the above gene and the transformed B. subtilis cells produced .beta.-amylase having the same thermostability as that of .beta.-amylase obtained from C. thermosulfurogenes.
