FRAMSTELLNING AV NYA PROTEASINHIBITORER MED ANGIVEN FORMEL GENOM ODLING AV STAMMAR TILLHORANDE DE KENDA ARTERNA STREPTOMYCES RAMULOSUS, STREPTOMYCES CITROCOLOR OCH STREPTOMYCES CATENULAE

摘要

Protease inhibitor which has strong inhibitory action against pepsin and other acid protease is produced by a microorganism of the genus Streptomyces. The protease inhibitor is recovered from the culture medium and purified and the purified protease inhibitor is used as an effective drug for the prevention and cure of hyperpepsia, hyperpepsinia and gastric and duodenal ulcers.
