Production of xanthomegnin and viomellein by isolates of Aspergillus ochraceus, Penicillium cyclopium, and Penicillium viridicatum.
Fungal isolates from legumes were cultured on rice and examined for production of the toxic mold metabolites xanthomegnin and viomellein. Six of 14 Aspergillus ochraceus isolates produced from 0.3 to 1.3 mg of xanthomegnin per g and 0.1 to 1.0 mg of viomellein per g. One of nine isolates of Penicillium cyclopium produced 0.1 mg of xanthomegnin per g and 0.06 mg of viomellein per g. Three of nin...
متن کاملPolyketides, Toxins and Pigments in Penicillium marneffei
Penicillium marneffei (synonym: Talaromyces marneffei) is the most important pathogenic thermally dimorphic fungus in China and Southeastern Asia. The HIV/AIDS pandemic, particularly in China and other Southeast Asian countries, has led to the emergence of P. marneffei infection as an important AIDS-defining condition. Recently, we published the genome sequence of P. marneffei. In the P. marnef...
متن کاملIsolation and Characterization of Sexual Spore Pigments from Aspergillus nidulans.
The homothallic ascomycete Aspergillus nidulans produces two types of pigmented spores: conidia and ascospores. The synthesis and localization of the spore pigments is developmentally regulated and occurs in specialized cell types. On the basis of spectroscopic evidence, we propose that the major ascospore pigment of A. nidulans (ascoquinone A) is a novel dimeric hydroxylated anthraquinone. The...
متن کاملSpecific detection of Aspergillus and Penicillium species from respiratory specimens by polymerase chain reaction (PCR).
A polymerase chain reaction (PCR) method capable of detecting both Aspergillus fumigatus infections, pulmonary non-fumigatus Aspergillus species (spp.) and Penicillium spp. from clinical specimens was established. The primer pair was designed on the basis of the sequence of the 18S-ribosomal RNA gene of A. fumigatus and P. notatum. A 385 bp product was successfully amplified by this PCR method ...
