ABSTRACT:
The present invention provides a process for producing cercosporamide comprising culturing a fungus belonging to the genusLachnumand/or fungus belonging to the genusPseudaegeritaand recovering cercosporamide from the culture thereof. In addition, the present invention provides cercosporamide acquired according to this production process. Further, the present invention provides novel microorganisms consisting ofLachnum fuscescensSANK 19096,Lachnum calycioidesSANK 12497,Lachnum caesaliatumSANK 10906, andPseudaegerita websteriSANK 11006.
