Ｓ－２－３５菌株产生的淀粉酶抑制剂对人体内的ａ－淀粉酶、唾液酸酶有明显的抑制作用。该产生菌在２８℃摇瓶发酵时，碳源利用率高于氮源利用率。发酵４８小时后，菌丝的生长速度随着碳源利用率的加速而加快。淀粉酶抑制剂的含量在２５小时后迅速提高，并在７２小时达最高峰。发酵液经活性炭吸附，ＤＥＡＥ－５２纤维索、ＣＭ－３２纤维素和ＳｅｐｈａｄｅｘＧ－２５层析后的活性部分经ＨＰＬＣ得三个活力峰。显色反应表明对茚三酮、双缩脉呈阴性反应，对吐伦、间苯二酚、Ａｎｔ－ｈｒｏｎｅ和ＫＭｎＯ＿４呈阳性反应。紫外光谱呈末端吸收，红外光谱在３３９１、１４１０、１０３０及９２７ｃｍ￣（－１）处有吸收峰。质谱测定Ａ组分分子量为９４４。
A-2-35 strains produce amylase inhibitors on the human body a-amylase, sialidase significant inhibitory effect. When the strain was fermented at 28 ℃, the utilization of carbon source was higher than that of nitrogen source. After 48 hours of fermentation, the mycelial growth rate accelerated with the utilization rate of carbon source. The level of amylase inhibitor increased rapidly after 25 hours and peaked at 72 hours. Fermentation broth activated carbon adsorption, DEAE-52 fiber cable, CM-32 cellulose and SephadexG-25 chromatography after the active part of the three peaks by HPLC. The color reaction showed negative reaction to ninhydrin and double systole and positive reaction to Turan, resorcinol, Ant-hrone and KMnO_4. The UV spectrum showed the end absorption, the infrared spectrum at 3391,1410,1030 and 927cm ~ (-1) at the absorption peak. Mass spectrometry A component molecular weight of 944.
