| natural occurrence of fungi and fungal metabolites in moldy tomatoes. | fresh tomatoes, homegrown and from supermarkets, with developing fungal lesions were collected. each lesion was sampled, and the resulting fungal cultures were identified morphologically and extracted for analyzes of secondary metabolites. the tomatoes were incubated at 25 degrees c for a week, extracted, and analyzed for fungal metabolites. extracts from pure cultures were compared with extracts from the moldy tomatoes and fungal metabolite standards in two hplc systems with dad and fld detecti ... | 2004 | 15675796 |
| two new penicillium species penicillium buchwaldii and penicillium spathulatum, producing the anticancer compound asperphenamate. | penicillium buchwaldii sp. nov. (type strain cbs 117181(t) = ibt 6005(t) = imi 30428(t) ) and penicillium spathulatum sp. nov. (cbs 117192(t) = ibt 22220(t) ) are described as new species based on a polyphasic taxonomic approach. isolates of p. buchwaldii typically have terverticillate conidiophores with echinulate thick-walled conidia and produce the extrolites asperphenamate, citreoisocoumarin, communesin a and b, asperentin and 5'-hydroxy-asperentin. penicillium spathulatum is unique in ha ... | 2013 | 23173673 |
