Abstract

A study of the coloring matter produced by Conidiobolus paulus Drechsler NRRL 2648 on potato-dextrose medium led to the isolation of a new dialdehyde unsaturated metabolite, (all trans)-2,4,6,8,10,12-tetradeca-1,14-hexenedial. The structure was characterized by MS and by 1H- and 13C-NMR. The compound inhibited the growth of the Gram-positive bacterium, Bacillus cereus, and the Gram-negative bacterium, Escherichia coli (MIC values of 10 micrograms and 50 micrograms, respectively).

摘要

一项关于保罗耳霉（Conidiobolus paulus Drechsler NRRL 2648）在马铃薯葡萄糖培养基上产生的色素的研究，导致分离出一种新的二醛不饱和代谢产物，（全反式）-2,4,6,8,10,12-十四碳-1,14-己二烯二醛。该结构通过质谱以及¹H-和¹³C-核磁共振进行了表征。该化合物抑制革兰氏阳性菌蜡样芽孢杆菌（Bacillus cereus）和革兰氏阴性菌大肠杆菌（Escherichia coli）的生长（最小抑菌浓度值分别为10微克和50微克）。
