Abstract

According to the present invention inhibitors for glycoside hydrolases, and in particular glucosidase inhibitors especially saccharase inhibitors, which are active in the digestive tract are formed by culturing organisms of the family Bacillaceae, particularly by strains of the genus Bacillus. It has also been found that certain strains of organisms of the family Bacillaceae, especially strains DSM 7, DSM 704 and DSM 675 produce the antibiotic known as 1-desoxynojirimycin. The invention therefore provides a method of producing 1-desoxynojirimycin which comprises culturing a 1-desoxynojirimycin producing organism of the genus Bacillus. Inhibitors for glycoside hydrolases and the invention includes methods for producing such inhibitors, pharmaceutical compositions containing the inhibitors and methods of treatment involving the use of the inhibitors.
