Production of sordarin and related metabolites by the coprophilous fungus Podospora pleiospora in submerged culture and in its natural substrate

Weber, R W S ; Meffert, A ; Anke, H and Sterner, Olov LU (2005) In Mycological Research 109(5). p.619-626
Abstract
Rabbit pellets collected from the field were colonized by Podospora pleiospora at the exclusion of other coprophilous fungi, suggesting antibiosis. in liquid culture, P. pleiospora produced sordarin (1); sordarin B (2), a new compound in which sordarose is replaced by rhamnose, hydroxysordarin (3); and sordaricin (4). The major compounds I and 2 exhibited minimum inhibitory concentrations of 0.5-2.5 mu g ml(-1) against the yeasts Nematospora coryli and Sporobolomyces roseus, but showed little or no activity against bacteria or coprophilous filamentous fungi. In liquid culture, the production of 1 and 2 together amounted to 2.7 mu g ml(-1), whereas in rabbit dung only 1 was produced at a similar concentration (2.3 mu g g(-1) fresh weight).... (More)

In liquid culture, the production of 1 and 2 together amounted to 2.7 mu g ml(-1), whereas in rabbit dung only 1 was produced at a similar concentration (2.3 mu g g(-1) fresh weight). The biosynthesis of these substances was unaffected by the presence of inoculum of other fungi tested (Sporoholomyces roseus or Penicillium claviforme) in liquid culture or on dung. Sordarin-type natural products are therefore synthesized by P. pleiospora at sufficiently high concentrations to account for antibiosis against yeasts, but not against filamentous fungi. (Less)
