    摘要: L-sorbose, an intermediate important in vitamin C synthesis, is produced in higher yield from D-sorbitol by microbiological oxidation using a microorganism which belongs to the genus Gluconobacter and which has decreased ability to grow with D-sorbitol as the single carbon source compared with that of its parent strains.

    摘要: Cyclic peptides and their salts have antagonistic activity on endothelin receptors and antagonistic activity on NK2 receptors. The peptides have the formula ##STR1## wherein X and Y each represent .alpha.-amino acid residues, A represents a D-acidic-.alpha.-amino acid residue, B represents a neutral .alpha.-amino acid residue, C represents an L-.alpha.-amino acid residue and D represents a D-.alpha.-amino acid residue having an aromatic ring group; wherein hydroxy, thiol, amino, imino and carboxyl groups can be substituted or unsubstituted. Pharmaceutical compositions containing such peptides are also described.
