Diversity, Virulence Factors, and Antifungal Susceptibility Patterns of Pathogenic and Opportunistic Yeast Species in Rock Pigeon (Columba livia) Fecal Droppings in Western Saudi Arabia

pigeon fecal droppings in public areas are a source of bacterial infectious agents, such as Salmonella, Campylobacter, and E. coli O157, and that they may significantly affect public health (Abulreesh et al. 2007; Abulreesh 2014). Carriage of pathogenic yeast in pigeon feces is a matter of growing interest and has been investigated worldwide, with much focus on the Cryptococcus species. Wu et al. (2012) reported the presence of eight different genera of yeast, such as Cryptococcus, Candida, and

first hours of the fermentation, regardless of the yeast strain applied. The acetaldehyde concentration decreased over the time with the decreasing productivity, reaching its lowest value at the 72nd hour of the process. The final concentration of acetaldehyde depended on the raw material used (ca 28.0 mg/l EtOH for maize mashes, 40.3 mg/l EtOH for rye mashes, and 74.4 mg/l EtOH for amaranth mashes). The effect of the used yeast strain was negligible.The overall concentration of the analyzed

GENOME SHUFFLING AS AN ALTERNATIVE METHOD OF IMPROVING THE PROPERTIES OF DISTILLERY YEAST

Modern technologies of bioethanol production require distillation yeast characterized by thermotolerance, osmotolerance and increased resistance to secondary metabolites. To date, no strains have been observed in nature which possess all of the above-mentioned characteristics. For many years, intensive research has been carried out to improve the technological properties of industrial strains. A number of methods have been developed to allow genetic improvement of distillery yeasts. One of the

The Ability of a Novel Strain Scheffersomyces (Syn. Candida) shehatae Isolated from Rotten Wood to Produce Arabitol

Arabitol is a polyalcohol which has about 70% of the sweetness of sucrose and an energy density of 0.2 kcal/g. Similarly to xylitol, it can be used in the food and pharmaceutical industries as a natural sweetener, a texturing agent, a dental caries reducer, and a humectant. Bio­technological production of arabitol from sugars represents an interesting alternative to chemical production. The yeast Scheffersomyces shehatae strain 20BM-3 isolated from rotten wood was screened for its ability

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

Microbes have evolved ways of interference competition to gain advantage over their ecological competitors. The use of secreted antagonistic compounds by yeast cells is one of the prominent examples. Although this killer behavior has been thoroughly studied in laboratory yeast strains, our knowledge of the antagonistic specificity of killer effects in nature remains limited. In this study, yeast strains were collected from various niches and screened for antagonistic activity against one toxin

New Look on Antifungal Activity of Silver Nanoparticles (AgNPs)

However, the studies of AgNPs interaction with cell structures of bacteria and yeasts are scarce. Only in few reports the location of AgNPs inside C. albicans cells was demonstrated under transmission electron microscopy (TEM) or scanning electron microscopy (SEM) (Kim et al. 2009; Radhakrishnan et al. 2018).

CANDIDA AURIS – EMERGING FUNGAL PATHOGEN

In recent years, the incoming information about the emergence of new superbacteria and superviruses has been causing growing anxiety. However, also fungi are with increasing frequency reported as the sources of intercontinental microbiological hazards. According to the latest reports, quickly spreading, multidrug-resistant and difficult to identify yeast Candida auris may soon become the center of attention for clinicians, laboratory diagnosticians and the groups of advisers on the hospital

The Effects of Nutrient Concentration, Addition of Thickeners, and Agitation Speed on Liquid Fermentation of Steinernema feltiae

Entomopathogenic nematode production in liquid fermentation still requires improvements to maximize efficiency, yield, and nematode quality. Therefore, this study was aimed at developing a more suitable liquid medium for mass production of  Steinernema feltiae, by assessing the effects of nutrient concentration, thickeners (primarily agar), and agitation speed on infective juvenile (IJ) yield. Base medium (BM) contained yeast extract (2.3%), egg yolk (1.25%), NaCl (0.5%), and

A Low-Tech Bioreactor System for the Enrichment and Production of Ureolytic Microbes

Ureolysis-driven microbially induced carbonate precipitation (MICP) has recently received attention for its potential biotechnological applications. However, information on the enrichment and production of ureolytic microbes by using bioreactor systems is limited. Here, we report a low-tech down-flow hanging sponge (DHS) bioreactor system for the enrichment and production of ureolytic microbes. Using this bioreactor system and a yeast extract-based medium containing 0.17 M urea, ureolytic

Emodin Reduces the Activity of (1,3)-β-D-glucan Synthase from Candida albicans and Does Not Interact with Caspofungin

Abstract Candidiasis is the most common opportunistic yeast infection, with Candida albicans as a paramount causative species. (1,3)-β-D-glucan is one of the three main targets of clinically available antifungal agents used to treat Candida infections. It is one of the most abundant fungal cell wall components. Echinocandins represent the newest class of antifungals affecting cell wall biosynthesis through non-competitive inhibition of (1,3)-β-D-glucan synthase. Therefore, treatment with

It is also crucial in assessment of the efficiency of microbial recovery media in the presence of a residual biocidal agent. In the present study, four commercially available peroxygen/silver-based disinfectant formulae – intended to be used in a pharmaceutical facility sanitization program – were tested at two dilutions against three Gram-positive cocci and one yeast

Prevalence and Antifungal Susceptibility of the Emerging Fungal Species, Candida nivariensis, Isolated in a Teaching Hospital in Poland

Introduction Non-albicans Candida (NAC) yeast-like fungi play a more active role in fungal infections. Candida glabrata, one of the most important yeast-like fungi of this group, is the second most common cause of candidiasis. Distribution of C. glabrata varies depending on the geographical area. Relatively high incidence of C. glabrata was observed in the northern part of Europe and in the USA in contrary to southern countries of Europe and Latin America where C. parapsilosis infections are
