Ochratoxin production by the Aspergillus ochraceus group and Aspergillus alliaceus.
Ochratoxin A is a toxic and carcinogenic fungal secondary metabolite; its presence in foods is increasingly regulated. Various fungi are known to produce ochratoxins, but it is not known which species produce ochratoxins consistently and which species cause ochratoxin contamination of various crops. We isolated fungi in the Aspergillus ochraceus group (section Circumdati) and Aspergillus alliac...
متن کاملOptimization of Antibacterial Compounds Production by Aspergillus fumigatus Isolated from Sudanese Indigenous Soil
The purposes of the present study were to screen the ability of Aspergillus fumigatus to produce antibacterial compounds using different growth parameters namely, pH, temperature, agitation and time of fermentation and investigate the effect of the yield against bacterial isolates. A. fumigatus was isolated from arable lands in Sudan and identified macroscopically and microscopically. The pure ...
متن کاملOccurrence of fungi and cytotoxicity of the species: Aspergillus ochraceus, Aspergillus niger and Aspergillus flavus isolated from the air of hospital wards.
OBJECTIVES The basic care requirement for patients with weakened immune systems is to create the environment where the risk of mycosis is reduced to a minimum. MATERIAL AND METHODS Between 2007 and 2013 air samples were collected from various wards of a number of hospitals in Kraków, Poland, by means of the collision method using MAS-100 Iso MH Microbial Air Sampler (Merck Millipore, Germany)...
متن کاملProduction of ochratoxin A by Aspergillus ochraceus isolated in Japan from moldy rice.
A simple thin-layer chromatography-fluorodensitometric method for quantitative analysis of ochratoxin A was developed. This method proved to be of use in investigating the production of the toxin and the nutritional factors affecting the toxin production by two strains of Aspergillus ochraceus isolated from moldy rice in Japan. These fungi produced large amounts of ochratoxin A in a nutrient so...
متن کاملAspergillus nodules in chronic granulomatous disease attributable to Aspergillus ochraceus
Aspergillus ochraceus is a rare pulmonary pathogen. A 39 year old male with COPD and chronic granulomatous disease presented with severe breathlessness and recurrent infections. CT scan demonstrated multiple pulmonary nodules diagnosed as chronic pulmonary aspergillosis. The patient's sputum grew Aspergillus ochraceus thrice over 6 months, alongside positive Aspergillus IgG and serum galactoman...
