although more than 3000 antibiotics have been reported from actinomycetes/ higher fungi; biotechnological potential of yeasts and yeast-like fungi with respect to production of antimicrobial compounds has not been sufficiently investigated. we examined the antimicrobial activity of 11 strains of aureobasidium pullulans (two new isolates and nine standard strains). all the strains of aureobasidi...

Understanding plant-microbe relationships can be important for developing management strategies for invasive plants, particularly when these relationships interact with underlying variables, such as habitat type and seedbank density, to mediate control efforts. In a field study located in California, USA, we investigated how soil microbial communities differ across the invasion front of Taeniat...

A computer model of the fungal colony that grew consuming limited amount of nutrient with three control parameters, growth rate, and nutrient level and diffusion, was constructed to make a basic morphology diagram of mycelial colony. To apply the diagram with those parameters to the mycelial growth of Aspergillus nidulans wild and mutant strains, the relation between the colony expansion and th...

Priority effects - the impact of a species' arrival on subsequent community development - have been shown to influence species composition in many organisms. Whether priority effects among arbuscular mycorrhizal fungi (AMF) structure fungal root communities is not well understood. Here, we investigated whether priority effects influence the success of two closely related AMF species (Rhizophagu...

The members of the Ras-like superfamily of small GTP-binding proteins are molecular switches that are in general regulated in time and space by guanine nucleotide exchange factors and GTPase activating proteins. The Ras-like G-proteins Ras, Rap and Ral are regulated by a variety of guanine nucleotide exchange factors that are characterized by a CDC25 homology domain. Here we study the evolution...

There has been a controversial issue in phylogenetic relationships among animals, fungi, and plants. Before Whittaker and Margulis (1 ) classified the fungi as a separate kingdom in their five-kingdom classification, fungi traditionally had been considered more closely related to plants than to animals. With the determination of the primary structures of small subunit rRNA and the proteins like...

This review highlights the presence and ecological roles of fungi in lakes, and aims to stimulate research in aquatic mycology. In the study of lentic systems, this field is an almost completely neglected topic and, if considered at all, has often been restricted to specific groups of fungi, such as yeasts, filamentous fungi (e.g. aquatic hyphomycetes), or phycomycetes (an obsolete taxonomic ca...

PURPOSE Patients with acquired immunodeficiency are particularly predisposed to fungal infections. The purpose of the study was evaluation of the presence of fungi in the environment of a ward where Human Immunodeficiency Virus (HIV) positive and Acquired Immune Deficiency Syndrome (AIDS) patients were treated. MATERIALS AND METHODS The evaluation of fungal presence in the indoor air and on t...

BACKGROUND Soil is well known to support the transient or ongoing existence of keratinophilic fungi and potential source of infection for human and animals METHODS Samples were collected from 67 sites of university campus like PG study centers, playgrounds, gardens, hostels, administrative blocks, library, bank, canteen and road side for the estimation of keratinophilic fungi using the hair b...

INTRODUCTION INTRODUCTION Due to the specific work environment, farmers are exposed to various biological occupational hazard. Among these factors significant are fungi present in the grain and also in the soil. The fungi may be the cause of human diseases including skin infections, asthma, allergic rhinitis and many others. AIM The aim of this study was to quantify and identify species of...
