Fulvoferruginin, a Carotane Antibiotic from Marasmius fulvoferrugineus

Marasmius fulvoferrugineus is a rather small agaric with a conspicuous reddish brown pileus which can be found quite frequently in the Great Smoky M ountains and the southern United States. Its natural habitats are plant debris or wood in mixed forests. It has been described as a new species by Gilliam [2], The species most close­ ly related is Marasmius siccus (Schwein.) Fr. which differs in t...

Antibiotics from basidiomycetes. X. Scorodonin, a new antibacterial and antifungal metabolite from Marasmius scorodonius (Fr.) Fr.

Scorodonin (1), a novel biologically active metabolite, was isolated from submerged cultures of the mushroom Marasmius scorodonius (FR.) FR. Its structure has been determined by chemical and physical methods. The antibiotic inhibits the growth of bacteria, yeasts, and filamentous fungi. In cells of the ascitic form of EHRLICH carcinoma the incorporation of thymidine and uridine into DNA and RNA...

Antibiotic Substances Separated from Sumac.

It has become evident (Osborn, 1943; Lucas and Lewis, 1944) that higher plants are potential sources of antibiotic agents. Several investigators (Little and Grubaugh, 1946; Atkinson and Rainsford, 1946; Sanders, Weatherwax, and McClung, 1945) have reported antibiotic effects of juices and of crude extracts of plants on various microorganisms. The active materials can be separated in some degree...
