In recent years, there has been increasing interest in the study of extremophilic microorganisms, which include halophiles and halotolerants. These able to survive thrive optimally a wide range environmental extremes, are polyextremophiles. this context, one main reasons for studying them is understand their adaptative mechanisms stress caused by extreme living conditions. paper, fungal strain Penicillium chrysogenum P13, isolated from saline soils around Pomorie Lake, Bulgaria, was used....
Fungal infections are a significant global public health challenge because of their widespread occurrence, morbidity, and profound social economic consequences. Antifungal resistance is also an increasing concern, posing substantial risk to health. There growing interest in searching for new antifungal drugs isolated from natural sources. This study aimed evaluate the activity novel mollusk fractions against fungal strains resistant nystatin amphotericin B. In addition, role oxidative stress...
Catalase (CAT) is an enzyme involved in the first line of cellular antioxidant defense. It plays a key role protection wide range Antarctic organisms against cold stress. Extracellular catalase very rare and data on it are extremely scarce. The aim present study was to select efficient producer extracellular from amongst filamentous fungi. Sixty-two fungal strains were investigated for their potential ability synthesize intracellular CAT. strain Penicillium rubens III11-2 selected as best...
Lactobacillus species are widely recognized for their probiotic potential, focusing on mechanisms of health benefits and protection. Here we conducted an in vitro investigation the potential with a role microbiome homeostasis four strains: Lactiplantibacillus plantarum L6 F53, Ligilactobacillus salivarius 1, helveticus 611. A broad spectrum antibacterial antifungal activity was determined. The strain-specific inhibition Staphylococcus aureus, Streptococcus mutans, Escherichia coli,...
Antarctica, with its harsh environmental conditions, is home to a wide variety of microorganisms, including filamentous fungi. The survival Antarctic mycoflora has led increasing interest in their adaptation. Extreme low temperatures, water availability, frequent freeze–thaw cycles, strong winds, ultraviolet radiation, etc., are all prerequisites for accelerated production reactive oxygen species (ROS) and the occurrence oxidative stress (OS). fungi have effective mechanisms cope damaging...
Fusarium solani (F. solani) and Alternaria (A. are among the most destructive pathogenic fungi affecting potatoes, causing significant crop losses in both field post-harvest conditions. Current control relies heavily on synthetic fungicides which pose serious environmental health risks. Therefore, there is a growing need to find efficient environmentally friendly alternatives combat fungal infections potatoes. This study offers chitosan (CS) zinc oxide (ZnO) nanoparticles (NPs) as potential...
Sialidases (neuraminidases, EC 3.2.1.18) are widely distributed in biological systems but there only scarce data on its production by filamentous fungi. The aim of this study was to obtain information about sialidase distribution fungi from non-clinical isolates, determine availability gene, and select a perspective producer. A total 113 fungal strains belonging Ascomycota Zygomycota compassing 21 genera 51 species were screened. Among them, 77 (11 orders, 14 families 16 genera) able...
The fungal strain,
Cold-active catalase (CAT) elicits great interest because of its vast prospective at the medical, commercial, and biotechnological levels. The study paper reports production cold-active CAT by strain Penicillium griseofulvum P29 isolated from Antarctic soil. Improved enzyme was achieved optimization medium culture conditions. Maximum demonstrated under low glucose content (2%), 10% inoculum size, temperature 20°C, dissolved oxygen concentration (DO) 40%. An effective laboratory technology...
Sialidases (neuraminidases) catalyze the removal of terminal sialic acid residues from glycoproteins. Novel enzymes non-clinical isolates are increasing interest regarding their application in food and pharmaceutical industry. The present study aimed to evaluate participation carbon catabolite repression (CCR) regulation cold-active sialidase biosynthesis by psychrotolerant fungal strain Penicillium griseofulvum P29, isolated Antarctica. presence glucose inhibited activity growing...
In order to meet the ever-growing needs of society, modern agriculture must develop sustainable farming and livestock production. Crops need phosphorus, a macronutrient found in soils, but they are only able utilize small quantities it. Chemical phosphate fertilizers ineffective environmentally harmful. The use microorganisms (bacteria, yeast, filamentous fungi, microalgae) that synthesize phytases is promising friendly alternative chemical fertilizers. Phytases also needed as feed additives...
