Screening and Identification of Yeasts Antagonistic to Pathogenic Fungi Show a Narrow Optimal pH Range for Antagonistic Activity

-sensitive strain of Saccharomyces cerevisiae and three pathogenic fungi. We demonstrate that some strains with antagonistic activity against these pathogenic fungi can be found in antagonist culture tests. These yeasts were identified as members of Trichosporon asahii, Candida stellimalicola, Wickerhamomyces anomalus, Ustilago esculenta, Aureobasidium pullulans, and Pichia kluyveri. The results indicated that the antagonistic activity of these killer yeasts has a narrow optimal pH range. Furthermore, we

In vitro Antagonistic Activity of Endophytic Fungi Isolated from Shirazi Thyme (Zataria multiflora Boiss.) against Monosporascus cannonballus

The term “Endophytes” denotes microorganisms that colonize plants’ internal tissues for part of or throughout their life cycle without producing any apparent adverse effect. The endophytic microorganisms include fungi, bacteria, and actinobacteria (Bacon and White 2000). Among them, fungi are the most common endophytic microorganisms (Staniek et al. 2008). Endophytic fungi are ecologically distinct polyphyletic groups of microorganisms, mostly belonging to the Ascomycota phylum (Jia et al. 2016

The Composition of Fungal Communities in the Rumen of Gayals (Bos frontalis), Yaks (Bos grunniens), and Yunnan and Tibetan Yellow Cattle (Bos taurs)

Introduction Ruminant animals lack the carbohydrate-active enzyme encoding genes, so feed (carbohydrate) metabolism is completely dependent on the microorganisms residing in their rumen (Kameshwar and Qin 2018). Current research on rumen fungi has focused on anaerobic rumen fungi. Anaerobic rumen fungi play a very important role in the digestion and metabolism of carbohydrates in the rumen (Gruninger et al. 2018; Kameshwar and Qin 2018). Anaerobic rumen fungi can secrete large amounts of

THE HUMAN MICROBIOME

The human microbiome is represented by bacteria, archea, viruses, including bacteriophages, and fungi. These microorganisms colonize the human body and are necessary for the maintenance of homeostasis, including human immune status. Even though human microbiome is vital for the functioning of the human organism, it is still poorly understood, especially when it comes to archea, but also viruses and fungi. The aim of this study is to present the current state of knowlegde about the

Chemical Signals of Vector Beetle Facilitate the Prevalence of a Native Fungus and the Invasive Pinewood Nematode

In China, the invasive Bursaphelenchus xylophilus, the vector Monochamus alternatus beetle, and associated fungi exhibit a symbiotic relationship causing serious losses to pine forests. Although this complex system has been intensively investigated, the role of vector beetles on the development of associated fungi and their indirect contribution to the prevalence of pinewood nematode (PWN) is yet unknown. Here, three of the highly prevalent fungal species, viz., Sporothrix sp. 1, Ophiostoma ips

CHARACTERISTICS AND FUNCTIONS OF HYDROPHOBINSAND THEIR USE IN MANIFOLD INDUSTRIES

Hydrophobins are surface active proteins produced by filamentous fungi. They play a role in fungal growth and their life cycle. Proteins with similar properties have been also found in prokaryotic organisms. Hydrophobins are characterized by a specific arrangement of cysteine residues, which form four disulfide bridges in the amino acid sequence. This construction gives hydrophobins their hydrophobic properties, allowing for their spontaneous assembly into amphipathic monolayers at hydrophobic

SPECIES DIVERSITY OF BACTERIA ASSOCIATED WITH FUNGI OF THE GENUS TUBER (TRUFFLES)

Truffles (Tuber spp.) are ascomycete hypogeous fungi, which form ectomycorrhizae with roots of trees, shrubs and herbaceous plants. Their fruiting bodies are valued for their distinctive aroma. The aroma might be partially due to complex bacterial community which colonizes their fruiting bodies. Some bacterial species are also believed to promote the truffle’ fruitification due to the fixation of nitrogen inside the developing truffles. Although truffles, especially of the species Tuber

Evaluation of Pochonia chlamydosporia and Purpureocillium lilacinum for Suppression of Meloidogyne enterolobii on Tomato and Banana

Meloidogyne enterolobii is one of the most important root-knot nematode in tropical regions, due to its ability to overcome resistance mechanisms of a number of host plants. The lack of new and safe active ingredients against this nematode has restricted control alternatives for growers. Egg-parasitic fungi have been considered as potential candidates for the development of bionematicides. In tissue culture plates, Pochonia chlamydosporia (var. catenulata and chlamydosporia) and

, mainly bio, physical and chemical properties of soil. Its physical and chemical properties have an influence on bacteria, fungi and invertebrates, both in field and laboratory conditions. Such effects on rhizosphere organisms are positive or negative depending on biochar raw material origin, charring conditions, frequency of applications, applications method and doses, but long term effects are generally positive and are associated mainly with increased soil biota activity. However, a risk assessment

Secondary Metabolites of Actinomycetes and their Antibacterial, Antifungal and Antiviral Properties

The growing resistance of microorganisms towards antibiotics has become a serious global problem. Therapeutics with novel chemical scaffolds and/or mechanisms of action are urgently needed to combat infections caused by multidrug resistant pathogens, including bacteria, fungi and viruses. Development of novel antimicrobial agents is still highly dependent on the discovery of new natural products. At present, most antimicrobial drugs used in medicine are of natural origin. Among the natural

Culturable Endophytes Diversity Isolated from Paeonia ostii and the Genetic Basis for Their Bioactivity

Abstract Paeonia ostii is known for its excellent medicinal values as Chinese traditional plant. To date, the diversity of culturable endophytes associated with P. ostii is in its initial phase of exploration. In this study, 56 endophytic bacteria and 51 endophytic fungi were isolated from P. ostii roots in China. Subsequent characterization of 56 bacterial strains by 16S rDNA gene sequence analysis revealed that nine families and 13 different genera were represented. All the fungal strains

Luffa cylindrica Immobilized with Aspergillus terreus QMS-1: an Efficient and Cost-Effective Strategy for the Removal of Congo Red using Stirred Tank Reactor

, industrial wastes carrying azo dyes must be pretreated prior to its disposal to the environment. The physical and chemical effluent-treatment strategies, for example, adsorption, synthetic precipitation, and flocculation, are inefficient because of the prerequisite of strong foundation, high cost, and generation of secondary-sludge (McMullan et al. 2001). Given the disadvantages of chemical treatments, microbial remediation procedures have gained strong consideration during recent decades. Fungi turned

THE PREVALENCE OF SYMPTOMATIC DERMATOPHYTOSES IN DOGS AND CATS AND THE PATHOMECHANISM OF DERMATOPHYTE INFECTIONS

1. Introduction Dermatomycoses are skin diseases caused by an infection of its surface layers and other keratinized structures such as hair and nails by fungi referred to as dermatophytes [106]. Based on their adaptation to life, these eukaryotic microorganisms may be divided into three groups: those that attack people, referred to as anthropophilic, those associated with animals – zoophilic and those that live in the soil – geophilic ones [35, 44]. Dermatophytes belong to eurybiotic organisms

Are Entomopathogenic Nematodes Effective Biological Control Agents Against the Carob Moth, Ectomyelois ceratoniae?

. Different concentrations (5, 10, 50, 100, and 160 IJ/cm2 of the arena) of S. feltiae and S. carpocapsae were applied in the field test. The mean mortality results from the last test were 10.89% and 26.65% for S. feltiae and S. carpocapsae, respectively. Finally, we found that these low virulence rates of the nematodes were attributed to inhibitory/repellency effects of saprophytic fungi within the infested pomegranates, a usual status of the infested fruits in autumn or winter
