1. Molecular characterization of yeasts isolated from traditional Turkish cheeses
Abstract Thirty-two yeast strains were identified by means of molecular methods isolated from traditional Turkish cheeses (Tulum, Kashkaval, Mihalic, Orgu, White, Sepet, and Goat). Debaryomyces hansenii and Torulaspora delbrueckii were found as predominant species in cheese samples. Other species which were identified were Kluyveromyces lactis, Candida parap

2. Characterization and comparison of yeasts from different sources for some probiotic properties and exopolysaccharide production
Abstract A total of 134 strains of yeasts isolated from fruits and vegetables (certain berry fruits, apples, pomegranates, carrots and grapes), free-range chicken feces and dairy products, and from 10 commercial yeast preparations were identified and subjected to analyses to determine their in vitro probiotic properties. Based on 26S rRNA sequence analysis a

3. Yeasts isolated from tropical fruit ice creams: diversity, antifungal susceptibility and adherence to buccal epithelial cells
Resumo Os sorvetes à base de frutas são produtos amplamente consumidos em países tropicais e, devido à sua composição, podem ser uma boa fonte de crescimento microbiano, incluindo patógenos oportunistas. Os objetivos deste estudo foram caracterizar as populações de leveduras presentes nos sorvetes brasileiros à base de frutas e investigar sua susce

5. Use of Maldi-Tof MS biosensor in microbial assessment of Brazilian kefir grains
RESUMO O objetivo deste estudo foi avaliar o uso do biossensor de Maldi-Tof MS na avaliação microbiana de grãos de kefir. Maldi-Tof MS é uma nova metodologia para o diagnóstico rápido de micro-organismos. Um total de 358 micro-organismos foram isolados, 31 foram leveduras e 327 foram bactérias (divididas em bactérias láticas e acéticas). Colônias

6. The isolation of pentose-assimilating yeasts and their xylose fermentation potential
ABSTRACT For the implementation of cellulosic ethanol technology, the maximum use of lignocellulosic materials is important to increase efficiency and to reduce costs. In this context, appropriate use of the pentose released by hemicellulose hydrolysis could improve de economic viability of this process. Since the Saccharomyces cerevisiae is unable to fermen

7. Identification by PCR and evaluation of probiotic potential in yeast strains found in kefir samples in the city of Santa Maria, RS, Brazil
Abstract Kefir is a product elaborated from the symbiotic fermentation of different microorganisms. The Kluyveromyces and Saccharomyces genera are the major representatives of the yeasts found in kefir microbiota. The only pobiotic yeast commercialized as an oral medication, is the Saccharomyces boulardii. The present work involved the microbiological qualit

8. High-temperature ethanol production using thermotolerant yeast newly isolated from Greater Mekong Subregion
Abstract The application of high-potential thermotolerant yeasts is a key factor for successful ethanol production at high temperatures. Two hundred and thirty-four yeast isolates from Greater Mekong Subregion (GMS) countries, i.e., Thailand, The Lao People's Democratic Republic (Lao PDR) and Vietnam were obtained. Five thermotolerant yeasts, designated Sacc

9. Oxidative stress and antioxidant response in a thermotolerant yeast
Abstract Stress tolerance is a key attribute that must be considered when using yeast cells for industrial applications. High temperature is one factor that can cause stress in yeast. High environmental temperature in particular may exert a natural selection pressure to evolve yeasts into thermotolerant strains. In the present study, three yeasts (Saccharomy

10. Identifying yeast isolated from spoiled peach puree and assessment of its batch culture for invertase production
Abstract The identification of yeasts isolated from spoiled Jubileu peach puree using the API 20C AUX method and a commercial yeast as witness were studied. Subsequently, the yeast’s growth potential using two batch culture treatments were performed to evaluate number of colonies (N), reducing sugar concentration (RS), free-invertase (FI), and culture-inve

11. Assessment of volatile organic compounds from banana Terra subjected to different alcoholic fermentation processes
Abstract Banana characteristics could provide yeast growth and support the action of yeast to produce beverages. The effects of enzymatic treatment, centrifugation, commercial yeast and two selected strains of Saccharomyces cerevisiae were investigated using the fermented banana Terra. Volatile organic compounds (VOCs) were determined by solid phase microext

12. Selection of Xilose-Fermenting Yeast Strains
ABSTRACT In Brazil, ethanol is obtained by fermentat of sugar cane juice using Saccharomyces cerevisiae. The cane juice extraction generates the bagasse that has been used for obtaining generation biofuel. However, the sugarcane bagasse has 30% pentose that cannot be fermented to ethanol by S. cerevisiae. Thus the aim of this study was to isolate a yeast abl
