Three kinds of amylase inhibitor (S-AI, S-GI and Haim) were obtained from the culture filtrate of Streptomyces sp. S-AI was produced by St, diastaticus subsp, amylostaticus and inhibited glucoamylase and various a-amylases . S-PI consisted., of 6 moles of glucose and 1 mole of unknown substances. The structure of S-AI was discussed. S-GI was a specific inhibitor for exotype glucanase and was produced by St, lavendulae . S-GI inhibited animal invertase, but did not inhibit microbial invertase. Haim was a proteineous inhibitor and produced by, St, griseosporus. Haim inhibited specifically animal a-amylases.

To confirm the promoting effect on fruit-body formation of basidiomycetes of Streptomyces-pepsin inhibitor (S-PI), a production-scale test was carried out with Pleurotus ostreatus. The best addition-time and concentration of S-PI were at temeprature-shift down and 2.5μg/ml, respectively, which agreed with those obtained in the laboratory. Under these conditions, high quality mushrooms were obtained consistently with 2.6-fold higher yield than in the control (control yield 50.7g/bottle ; yield with 2.5 μm/ml of S-PI, 131g/bottle). Furthermore, this promoting effect of S-PI was constant throughout all seasons.
