Novel oligosaccharide substances, TAI-A and TAI-B, possessing a strong inhibitory activity to amylase and invertase are obtained by inoculating a seed of the strain of Streptomyces calvus TM-521 into aqueous nutrient medium, cultivating this with shaking or by a submerged culture method with aeration, and separating the produced amylase inhibitors TAI-A and TAI-B from the cultured broth. |
