Identification of a new enterotoxin as enterotoxin C.

abstract：:The gene for beta-amylase was isolated from Bacillus polymyxa by molecular cloning in B. subtilis. B. subtilis cells containing this gene express and secrete an amylase which resembles the B. polymyxa beta-amylase and barley beta-amylase in terms of the products it generates during carbohydrate hydrolysis. Starch hydr...
