Abstract:

The study of Endophytic fungi in the medicinal plants showed quite a variation. The plant Ocimum sanctum showed six types of fungi Trichoderma viridae, Fusarium solani, Gliocladium roseum, Cladosporium sp., Cladorrhinium sp. and Nigrospora sp. that were isolated from rhizosphere and found to be 42.8 % of the population of total fungi isolated, while only one type of endophyte, Mycelia sterilia was 14.2% of the total population of the isolates. The four fungi Fusarium solani, Gliocladium roseum, Mycelia sterilia and Nigrospora sp. were isolated as endophytes. with 42.8% of the total population

Abstract:

The occurrence of yeast-like fungi in the most important infection portals of the respiratory system in 200 randomly chosen students of biology and veterinary medicine was examined. The students come into direct contact with plants and animals that may be colonised by fungi belonging to various systematic groups. Nine species of yeast-like fungi, including 7 species determined in the biologists, were recorded in the subjects. <em>Candida tropicalis</em> and <em>Candida albicans</em> were the most frequently isolated fungi. The greatest number of fungi was isolated from

Abstract The electrochemical behavior of pure aluminum, 2024 alloy and mild steel have been studied in the presence of several species of fungi and bacteria isolated from kerosene fuels storage and distribution systems. Microbial growth facilitates passivity breakdown mainly through the action of organic acidic metabolites derived from hydrocarbon degradation. Their corrosive effect depends on the pH and electrolyte composition of the medium, especially with reference to chloride and nitrate levels. Microbial adhesion to the metal surface enhances metal dissolution. The metabolic activities of

Abstract:

Abstract Many northern Canadian water distribution systems operate a significant portion of the year at temperatures less than 10° Celsius (C) and for certain months of the year operate at less than 5° C. Few studies are available which examine the contribution of microbially influenced corrosion (MIC) to deterioration of these systems. Initial investigations into the effects of MIC on northern water distribution systems indicates a diverse population of bacteria and fungi living in these corrosion biofilms. These organisms appeared to have the metabolic capabilities to contribute to the net c

Abstract Many of the monuments related to Mayan civilization are suffering deterioration by environmental factors (high temperatures and relative humidities), increasing contamination by natural and anthropogenic sources, and by the action of micro and macroorganisms. Archeological sites and historical monuments in the Mayan area were constructed with different limestones which offer different degradation resistance to the various types of contamination. Two different archeological sites in the Yucatan peninsula, Mexico, were chosen for this study: the urban nucleus of Uxmal, located in a rura

Aerobic and anaerobic bacteria were found in low numbers in sump water, while fungi were rarely present. Numbers of aerobic bacteria and fungi were much higher in biofilms from the tank surface. Common aerobic bacteria were identified belonging to the genera Bacillus and Kurthia. Two fungal isolates were identified as Penic

Abstract:

The research is aimed at studying the antagonistic relationships of five isolates of the genus Trichoderma fungi in relation to the Alternaria sp. fungus. The pathogen was isolated from diseased walnut leaves. In the work was used the method of double cultures on agar media. As a result, 160 the inhibition rate of Alternaria pathogen by Trichoderma fungi was determined. For isolate №3 the rate was 90%, for isolate №2 - 85%, isolate №4 inhibited the pathogen by 75%, isolate №1 - by 65%. Isolate №5 and strains T.virens and T. lignorum suppressed the growth of Alternaria by 40-50%.

Abstract:

Due to the overuse of antibiotics, antibiotic resistance has become a global health crisis, and has forced an exploration of alternative antibacterial agents. This review explores natural solutions through the antibacterial potential of medicinal plants and their symbiotic endophytic fungi. Medicinal plants have been utilized for centuries to treat infections because of their rich phytochemical content, including alkaloids, flavonoids, and saponins, which exhibit antibacterial properties. Their efficacy is measured through minimum inhibitory concentration (MIC) assays, which showcase their abi

Abstract:

A major consideration in the development of biopesticides based on entomopathogenic fungi has been the virulence and pathogenicity in terms of mean time of mortality and mean lethal concentration against the target insect. Virulence factors as chitinases degrade insect chitin facilitating the hyphal penetration through the cuticle. In this sense, Beauveria bassiana chitinases are an important cuticle-degrading group of enzymes implicated in the pathogenesis to insects, with high potential to develop biotechnological tools for in pest control. The aim of this study was to characterize chitinase

Abstract:

Fungal plant pathogens are responsible for extensive annual crop and revenue losses throughout the world. To better understand why fungi cause diseases, we performed gene-disruption mutagenesis on several pathogenic Colletotrichum species and demonstrated that pathogenic isolates can be converted to symbionts (mutualism, commensalism, parasitism) expressing non-pathogenic lifestyles. The objectives of this proposal were to: 1- generate crop-specific mutants by gene disruption that express mutualistic lifestyles, 2- assess the ability of the mutualists to confer disease resistance, drought tole

Spore germination is a common and fundamental event in fungal development and in many instances an essential phase of fungal infection and dissemination. Spore germination is also critical for hyperparasites to function as biocontrol agents as well as in fermentation proceses. Our common objective is to understand the mechanisms which regulated spore germination and identify factors involved in pathogenicity related prepenetration development. Our approach is to exploit the overall similarity among filamentous fungi using both a plant pathogen (Colletotricum trifolii) and a model system that i
