A total of 145007 reads were obtained from pyrosequencing for all the 4 samples. The total count ranged from 11,301,014 (Mecca old road) to 23,503,512 bp (Thuwal). A total of 460 fungal species belonging to 133 genera, 58 families, 33 orders, 13 classes and 4 phyla was identified across the four sites. The most abundant phylum at all four sites was Ascomycota followed by Basidiomycota. Four phy...

Microbial transformation can strengthen the antioxidant and antitumor activities of polyphenols. Polyphenols contents, antioxidant and antitumor activities of pine polyphenols and its biotransformation extracts by Aspergillus niger, Aspergillus oryzae, Aspergillus carbonarius, Aspergillus candidus, Trichodermas viride, Mucor wutungkiao and Rhizopus sp were studied. Significant differences were ...

During a study on the mycobiota of brazil nuts (Bertholletia excelsa) in Brazil, a new Aspergillus species, A. bertholletius, was found, and is described here. A polyphasic approach was applied using morphological characters, extrolite data as well as partial β-tubulin, calmodulin and ITS sequences to characterize this taxon. A. bertholletius is represented by nineteen isolates from samples of ...

During 2002-03 forty-four different barley growing regions in East Azarbaijanprovince of Iran were sampled for epiphytic fungi. Isolation of fungi was achieved using standard methods. As the result 374 hyphomycetous isolates were obtained that were placed in 22 genera and 49 species based on colony morphology and microscopic features (Table 1). Among these, Acremonium egyptiacum, A. sclerotigen...

To the Editor: Alveolar proteinosis (AP) is a rare disease which affects the lungs diffusely and is characterized by the deposition of protein-like material rich in phospholipids. This material is characteristically PAS positive and does not cause interstitial alveolar inflammation; thus the degree of fibrosis minimal. Signs and symptoms are nonspecific and patients are generally asymptomatic b...

background: this study was conducted to determine the species of oral and non-oral microorganisms in dental laboratory pumice in order to undertake the necessary disinfection control protocols. methods: fourteen active and well-known dental laboratories of tehran entered our study. samples of pumice were collected from polishing containers in a completely sterilized and controlled condition. th...

The biodegradability of the principal component of synthetic detergent products known as linear alkylbenzene sulphonate (LAS) has been contentious, hence the need to evaluate its primary biodegradation by indigenous microorganisms in wastewater ecosystem. The native microbial consortium of a wastewater ecosystem found to utilize detergent components were characterized using standard and convent...
