BACKGROUND/AIM Mycological media that promote spore production are essential for the diagnosis of dermatophytosis. However, these culture media frequently become contaminated by multiple fungal or bacterial species during culture. The aim of this study was to compare the contamination rates of 6 culture media used for the isolation and identification of dermatophytes, including Borelli's lactri...

Rice blast (causal agent: Pyricularia oryzae) is an important disease of rice in Sarawak. Understanding the pathogen’s morphological characteristics, genetic diversity and pathogenicity important. Having a suitable medium for culturing maintaining P. oryzae to ensure availability inoculum or materials under laboratory conditions. Oatmeal agar (OMA) potato dextrose (PDA) are common media used gr...

AIMS To investigate how linoleic acid affects conidial production and sclerotial development in a strictly mitotic Aspergillus parasiticus field isolate as related to improving biocompetitivity of atoxigenic Aspergillus species. METHODS AND RESULTS We disrupted A. parasiticusDelta12-oleic acid desaturase gene (odeA) responsible for the conversion of oleic acid to linoleic acid. We examined co...

In a course of survey during growing seasons of 2002-04, various fields and pastures in 23 Iranian provinces were sampled. Some 1200 isolates of Fusarium from root, crown, stem and spike of various plants belonging to the family Poaceae were recovered using Nash-Snyder selective medium and purified on potato dextrose agar (PDA). Based on morphological characteristics, 32 Fusarium species were i...

Non-syndromic thoracic aortic aneurysms and dissections (TAADs) are inherited in an autosomal dominant manner in approximately 20% of cases. Familial TAAD is genetically heterogeneous and four loci have been mapped for this disease to date, including a locus at 16p for TAAD associated with patent ductus arteriosus (PDA). The defective gene at the 16p locus has recently been identified as the sm...

NaCl, KCl, or PEG (polyethylene glycol)-amended potato dextrose broth (PDB), and potato dextrose agar (PDA) are essential for pure culture studies of water stress on fungi. Direct information on the actual water potential (WP) of this salt-amended PDB and PDA is lacking. Much fungal research in the past calculated WP of these salt-amended growth media by adding the WP of their constituents take...

The soil samples were collected and were primarily screened for isolation of amylase producing fungi. Among the isolated fungi, amylase producing isolates were identified by growing on starch agar media. The isolates exhibiting the maximum zone of clearance on starch agar media by iodine were identified and were subcultured on potato dextrose agar (PDA). The isolates were morphologically charac...

With the rapid development of the Internet based connection to di erent devices such as PDA, WAP phones, and pagers, one-document-many-presentation has become a converging issue in the development of various markup languages for description of content and presentation. Many works have been done in this area while few of them consider the issue of rich media. To address it, this paper proposes t...

Macrolepiota procera, one of edible mushrooms belongs to Agaricaceae of Basidiomycota, has a good taste and good medicinal value. As a preliminary study for the development of artificial cultivation method of edible mushroom, cultural characteristics of M. procera was investigated on various culture media under different environmental conditions. Mycelial growth was compared on culture media co...
