Napthrene Compounds from Mycelial Fermentation Products of Marasmius berteroi

Fermentation-derived compounds as a source of new products

New products may be sought by modifying older fermentation products, exemplified by the semisynthetic antibiotic tilmicosin and other derivatives of tylosin. Another approach is to screen fermentation broths, exemplified by the discovery of the structurally-unique insecticidal macrolide spinosad. The polyketide class of fermentation products encompasses a wide diversity of chemical structures a...

Effects of extracts derived from pistachio by-products on ruminal fermentation and methane production

The objective of this study was to evaluate the effects of different doses of pistachio by-product (PBP) extracts supplemented with alfalfa hay (AH) or barley grain (BG) on microbial fermentation in an in vitro fermentation system. The total extracted phenolic compounds were 36.96, 65.78, 67.02 and 8.85% and total extracted tannin contents were 37.11, 59.64, 56.87 and 7.55% when PBP was extract...

Fermentation Products of Cellulose

IN WORKING on the products resulting from the anaerobic decomposition of biologic waste material, the writers, with others (1), have observed that the reactions, which are brought about by bacteria, cause the formation of considerable amounts of gas. This gas is principally methane and carbon dioxide, with small amounts (3-5 per cent) of hydrogen and nitrogen, the latter probably from solution ...

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...
