To evaluate the incidence of fungi producing ochratoxin A (OA) in Portuguese wine grapes, a survey was conducted in 11 vineyards, from four winemaking regions each with distinct climatic conditions. From setting to the harvesting period, a total of 1,650 berries were sampled by plating methods. Out of 370 aspergilli and 301 Penicillium strains isolated, 14% of the aspergilli were OA-producing s...

We developed a PCR-based assay to differentiate medically important species of Aspergillus from one another and from other opportunistic molds and yeasts by employing universal, fungus-specific primers and DNA probes in an enzyme immunoassay format (PCR-EIA). Oligonucleotide probes, directed to the internal transcribed spacer 2 region of ribosomal DNA from Aspergillus flavus, Aspergillus fumiga...

Antimicrobial activity of different culture extract of Oudemansiella sp grown on liquid medium (MYGP) were tested. Different fungi (C. albicans, C. lipolytica, Saccharomyces cervisiea, Cladosporium herbarum, and Aspergillus niger) and bacteria (Microccocus luteus, E. coli, Staphylococcus aureus, and Staphylococcus epidermidis) were used as test organisms. Various antimicrobial assay metho...

Phylloplane fungi of Chlorophytum tuberosum were screened for their antagonistic activities against Colletotrichum dematium in vitro. Volatiles produced from the cultures of Trichoderma harzianum ISO-1 showed maximum inhibition of mycelial growth of C.dematium followed by T. piluliferum, T. harzianum ISO-2 and Aspergillus niger,

Biotransformation of tryptophan to tryptamine and 3-methyl-indole by Psilocybe coprophila was performed. On the other hand, Aspergillus niger was able to transform tryptophan to 5-hydroxy-tryptophan. P. coprophila biotransformed 5-hydroxy-tryptophan to 5-hydroxytryptamine. These results prove once more that fungi are good tools to establish hydroxyindole derivatives.

Current study has evaluated the decolorization of textile dye Red 3BN by Peniciliium chrysogenum, Cladosporium sp. and Aspergillus niger, isolated from textile industry effluent at Bangalore. The organisms were maintained in the laboratory in Potato Dextrose Agar medium. Production of the enzyme laccase by all the 3 strains of fungi has been confirmed through guaiacol bioassay followed by decol...

To evaluate the contamination risk of the improper storage of pistachio nuts was studied in the major location of Saudi Arabia by studying the fungi associated with non and salted pistachio nuts. The infection with Aspergillus flavus and A. niger and treatment of this infection with some abiotic factors , salting and fumigation with acetic acid on the invasion and colonization were also studed....

investigating the decomposition of crop residues using woodborn and soilborn saprophytic fungi this experiment was conduceted to evaluate the effect of some fungi on decomposition of crop residues. crop residues from rice, wheat, cotton, canola and soybean were inoculated with pleurotus ostreatus, phanerochaete chrysoporium, aspergillus niger and trichoderma viride in vitro. after 30 days, hemi...

Bacteria associated with 6 habitats of groundnut were evaluated for their broad-spectrum antifungal activity and suppression of collar rot (Aspergillus niger) of groundnut. Three hundred and ninety-three strains were tested against 8 fungal pathogens of groundnut including 5 necrotrophic fungi, Aspergillus flavus, A. niger, Rhizoctonia bataticola, Rhizoctonia solani, and Sclerotium rolfsii, and...
