Abstract

Crocacin was isolated from the biomass of the myxobacterium Chondromyces crocatus, strain Cm c3. It inhibited the growth of a few Gram-positive bacteria and a wide spectrum of yeasts and molds. In beef heart submitochondrial particles, crocacin blocked the electron transport within the bc1-segment (complex III) and caused a red shift in the reduced spectrum of cytochrome b with a maximum at 569 nm.

摘要

番红菌素是从粘细菌鳄鱼软骨霉(Chondromyces crocatus)菌株Cm c3的生物质中分离出来的。它能抑制一些革兰氏阳性细菌以及多种酵母和霉菌的生长。在牛心亚线粒体颗粒中,番红菌素会阻断bc1段(复合体III)内的电子传递,并导致细胞色素b还原光谱出现红移,最大红移波长为569纳米。
