The effect of ecological aspects of distribution of potential toxin-producing micromycetes on stored apple fruit was investigated at the Lithuanian Institute of Horticulture and Institute of Botany in 2004–2005. Fungi of twenty species belonging to eight genera were isolated from rotten and healthy apple fruits. Penicillium expansum and Penicillium italicum showed a high frequency of occurrence...

The activities of ligninperoxidases from Penicillium citrinum MTCC 3565, Fusarium oxysporum MTCC 3379 and Aspergillus terreus MTCC 3374 have been assayed and the enzymatic characteristics like Km, pH and temperature optima using n-propanol as the substrate have been reported. The results suggest that n-propanol can substitute veratryl alcohol as substrate for assaying ligninperoxidase activitie...

The biotechnological potential of pectinolytic fungi isolated from citrus fruits was studied. Seventy five fungal isolates were isolated from decayed citrus fruits. All of these isolates were screened for their pectinolytic activity. Thirty six out of seventy five isolates proved to have pectinolytic activity. These isolates were identified and classified into twenty strains belonging to eleven...

Two distinct reservoirs of mycotoxins exist in fungal-infected cereal grains--the fungal spores and the spore-free mycelium-substrate matrix. Many fungal spores are of respirable size and the mycelium-substrate matrix can be pulverized to form particles of respirable size during routine handling of grain. In order to determine the contribution of each source to the level of mycotoxin contaminat...

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...

A large number of microorganisms are capable of degrading cellulose, only a few of these microorganisms produce significant quantities of enzymes capable of completely hydrolysing cellulose. Fungi are the main cellulase-producing microorganisms. In this purposed study, seventeen fungal species belonging to three genera i.e. Trichoderm, Aspergillus and Penicillium were isolated from different so...

This study was conducted to estimation of fungal species and aflatoxin B1 in some types Spices Salah Al-deen governorate markets. In this Six Aspergillus were detected which A. flavus, parasiticus, fumigatus, terreus, ochraceus niger 5 genus fungi Fusarium verticillioides, Penicillium, Mucor, Alternariaand Rhizopus isolated on the three media used. The results show presence mycotoxins all sampl...

The aim of this research was the analysis of the possible antagonistic effect of Penicillium oxalicum over the pathogen rice fungus A. alternata under different conditions of temperature, water activity and culture media. The macroscopic study of the dual growth revealed that according to the Index of Dominance P. oxalicum was more competitive that A. alternata at 25°C whereas at 15°C was this ...

The important developments in industrial fermentation lead to the utilization of microbial enzymes in different applications. Selected organisms Aspergillus fumigatus, A. terreus, Penicillium chrysogenum, P. funiculosum and Fusarium moniliforme. Various environmental parameters like pH, temperature and nutritional parameters such as carbon and nitrogen sources were investigated to optimize the ...

UNLABELLED BACKGROUND Petroleum pollution is a global disaster and there are several soil cleaning methods including bioremediation. METHODS In a field study, fugal strains were isolated from oil-contaminated sites of Arak refinery (Iran) and their growth ability was checked in potato dextrose agar (PDA) media containing 0-10% v/v crude oil, the activity of three enzymes (Catalase, Peroxid...
