Impact of antagonistic yeasts from wine grapes on growth and mycotoxin production by Alternaria alternata

Journal of Applied Microbiology, 2021
Alternaria alternata is a major contaminant of wine grapes, meaning a health risk for wine consumers due to the accumulation of toxic metabolites. To develop a successful biofungicide, the effectiveness of epiphytic wine grape yeasts against A. alternata

Linear, non-mitochondrial plasmids of Alternaria alternata

Current Genetics, 1992
Three plasmids, with sizes of 7.0 kbp, 6.8 kbp, and 5.0 kbp and designated pAal-1, pAal-2 and pAal-3 respectively, have been found in a tentoxin-producing isolate of Alternaria alternata. Exonuclease digestions show these plasmids to be linear with blocked 5' ends.

Interstrain spheroplast fusion of Alternaria alternata

Applied Microbiology and Biotechnology, 1992
Auxotrophic and drug resistant colonies of Alternaria alternata were selected following UV mutagenesis of spheroplasts and genetic transformation with pDH25. Intrastrain cell fusion of certain A. alternata parental strains induced by polyethylene glycol occurred at an average rate of 0.35%; interstrain fusions occurred at a rate of 0.08%.

Phaeohyphomycosis caused by Alternaria alternata in a cat

Journal of the American Veterinary Medical Association, 1988
Phaeohyphomycosis caused by Alternaria alternata was diagnosed in a 6-year-old cat. A lesion in the nose resulted in enlargement of the dorsum of the nose. Similar appearing lesions had been removed from the dorsum of the nose 1 and 4 years earlier. The lesion recurred 3 months after surgical excision and irregular administration of ketoconazole.

Bicycloalternarenes produced by the phytopathogenic fungus Alternaria alternata

Phytochemistry, 2000
Eleven compounds, ACTG toxins A and B and nine new substances named bicycloalternarenes (BCAs), were isolated and characterized from the culture filtrate of the phytopathogenic fungus Alternaria alternata. Under acidic conditions, these mixed terpenoids convert to pairs of tricycloaltenarenes that can be used for identification of the native compounds.

Mannitol metabolism in the phytopathogenic fungus Alternaria alternata

Fungal Genetics and Biology, 2007
Mannitol metabolism in fungi is thought to occur through a mannitol cycle first described in 1978. In this cycle, mannitol 1-phosphate 5-dehydrogenase (EC 1.1.1.17) was proposed to reduce fructose 6-phosphate into mannitol 1-phosphate, followed by dephosphorylation by a mannitol 1-phosphatase (EC 3.1.3.22) resulting in inorganic phosphate and mannitol.

Bioactive metabolites from the endophytic fungus Alternaria alternata

Fitoterapia, 2014
Two altenuene derivatives (1-2) and one isocoumarin (3), together with six known compounds (4-9) were isolated from solid cultures of an endophytic fungus Alternaria alternata, obtained from the fresh branches of Camellia sinensis. Chiral analysis revealed the racemic nature of 1 and 2, which were subsequently resolved into two pairs of enantiomers [(+)

Soft contact lens contamination by Alternaria alternata

Medical Journal of Australia, 1984
Two cases of contact lens contamination by the fungus, Alternaria alternata, are described. In both patients, mild ocular irritation was the presenting symptom but neither suffered fungal infection of the eye. To our knowledge, A alternata has not previously been reported as a contaminant of contact lenses, although it is an ubiquitous saprophyte and ...

Two cases of cutaneous phaeohyphomycosis by Alternaria alternata and Alternaria tenuissima

Mycopathologia, 1997
Two cases of cutaneous phaeohyphomycosis, one with a nodular appearance and the other with an erythematous infiltrating patch, are reported in immunocompromised patients. Diagnosis was based on histological examination, which revealed hyphae and round-shaped fungal cells in a granulomatous dermal infiltrate, and on identification of the moulds when ...
