Abstract

A peptide was obtained from culture filtrates of a bacterium which was newly isolated and tentatively named Bacillus cereus SW. The peptide was composed of Asx, Ser, Glx, Leu, Tyr, Pro, and an unknown amino acid in a ratio of 2:1:1:1:1:1:1, but, unless hydrolyzed with HCI, it was ninhydrin reaction negative. The peptide effectively inhibited the growth of all fungi and yeasts so far examined, whereas it inhibited none of the bacteria tested.

摘要

从一种新分离出的暂定名为蜡样芽孢杆菌SW的细菌的培养滤液中获得了一种肽。该肽由天冬氨酸、丝氨酸、谷氨酰胺、亮氨酸、酪氨酸、脯氨酸和一种未知氨基酸按2:1:1:1:1:1:1的比例组成,但除非用盐酸水解,否则它与茚三酮反应呈阴性。该肽有效抑制了迄今为止所检测的所有真菌和酵母的生长,而对所测试的细菌均无抑制作用。
