The ascomyceteLachnumpapyraceum is an efficient producer of bioactive and chlorinated metabolites, in which chlorine to some extent can be exchanged for bromine in fermentations to which bromide has been added. However, large amounts of bromide (100 mM CaBr2 alter the secondary metabolism of the fungus, and it produces papyracillicacid as the main metabolite. Papyracillicacid is a new bioactive
子囊菌Lachnum papyraceum是一种有效的生物活性和氯化代谢物的生产者,在其中添加了溴化物的发酵中,氯在某种程度上可以交换为溴。然而,大量的溴化物(100 mM CaBr 2改变了真菌的次生代谢,并产生了草吡咯酸作为主要代谢产物。草吡咯酸是一种新的具有生物活性的1,6-二氧杂螺环[4,4]壬烯衍生物,与开链形式,与霉菌毒素青霉素有关。
