• 中文摘要： 鏈黴菌SC,產生的SC4抗生素由含胍基之鹼性物質及至少八種對Ninhydrin呈陽性之物質所構成。其中之六種是氨基乙酸、氨基丙酸、絲氨酸、二氨基已酸、組織氨酸及毗咯陡甲酸一〔2〕。另外二種是未知物質。 SC,抗生素是小分子化合物。pronase,胰蛋白?、胃蛋白及木瓜蛋白釀對此抗生素之活性沒有影響。此抗生素在中性及酸性溶液中頗為穩定，但是在鹼性溶液容易分解“
• 英文摘要： SC4 antibiotic produced by Streptomyces SC4 consists of at least eight ninhydrinpositive compounds and a basic moiety which bears guanidinium group. Six of theeight ninhydrin positive compounds were identified as glycine, alanine, serine,lysine, histidine and proline. The other two compounds were unidentified. Size of the antibiotic is relatively small and the antibiotic activity was notsignificantly affected by pronase, trypsin, pepsin and papain. The antibiotic wasstable in neutral and acidic solutions, while it was labile in alkaline solution.
