AIMS To compare the AUXACOLOR yeast identification system with the API 20C system. METHODS Yeast isolates (n = 215), comprising 16 species, were identified using the AUXACOLOR system and the API 20C system. Isolates that could not be identified with the API 20C system or which produced discrepant results in the two systems were identified by assimilation and fermentation procedures. RESULTS...

CHROMagar Candida is a novel, differential culture medium that is claimed to facilitate the isolation and presumptive identification of some clinically important yeast species. We evaluated the use of this medium with 726 yeast isolates, including 82 isolated directly on the medium from clinical material. After 2 days of incubation at 37 degrees C, 285 C. albicans isolates gave distinctive gree...

Yeast's ability to restrict the growth and kill other yeasts, fungi and bacteria has been known for over 50 years. Killer activity was detected in yeasts deposited in the world collections or isolated from natural habitats. In this study, isolates from the forest environment, leaves of fruit trees, flower petals, cereals and frozen fruit have been screened in terms of their killer activities. K...

Blastomycosis, a systemic fungal disease, caused by the dimorphic fungus Blastomyces dermatitidis, has continually presented clinicians with concerns with regard to laboratory diagnosis and prevention. For years researchers have strived to develop antigens with a high degree of sensitivity and specificity. The purpose of this study was to gain a better understanding of how two novel yeast lysat...

A total of 381 fully identified yeast isolates were tested by the germ tube (GT) and Albistrip (Lab M Ltd., Bury, United Kingdom) methods, and the results were compared. As a test system for the identification of Candida albicans, the Albistrip showed two false-positive and two false-negative results, whereas the GT showed seven false-negative and no false-positive results. With the same method...

Three recently isolated extremely acidophilic archaeal strains have been shown to be phylogenetically similar to Ferroplasma acidiphilum Y(T) by 16S rRNA gene sequencing. All four Ferroplasma isolates were capable of growing chemoorganotrophically on yeast extract or a range of sugars and chemomixotrophically on ferrous iron and yeast extract or sugars, and isolate "Ferroplasma acidarmanus" Fer...

The aim of this study was to evaluate the efficacy of five antiseptics, three surface disinfectants and UV radiation against a wide range of clinical and environmental yeast isolates. Their efficacy against pure cultures, yeast mixtures and biofilms (prepared by culturing yeasts in Sabouraud broth containing a final concentration of 8% glucose) was tested. Three clinical isolates of Candida alb...

Alcoholic fermentation is a polimicrobial process involving a large number of genera and species of yeast and bacteria. Th e major yeast genera involved in this process belongs to the Saccharomyces spp. Th e aim of this study was the isolation, identifi cation and determination of genetic diversity of indigenous Saccharomyces cerevisiae natural population taken from cv. Plavac mali from seclude...

Septoria leaf blotch caused by Zymoseptoria tritici is one of the most harmful diseases in Belarus. Isolates pathogen were obtained from northern, central and southern populations: 2018–2019, whichvaried significantly among structure colonies. The rate fungal isolates forming yeast-like colonies decreased 55.0 % North Belarus to 6.7 South, whereas incidence filamentous increased 31.3 80.0 %, re...

the biocontrol agents candida  membranifuciens (isolates a4 and a5), pichia  guilliermondi (a6) and bacillus subtilis (b2 and b6) were tested both individually and in combination for biological control of the grey mold in fruit apple caused by botrytis cinerea pers.:fr. regarding the compatibility of the biocontrol agents, it showed that antagonists were compatible with each other according to ...
