Enzyme Contribution of Non-Saccharomyces Yeasts to Wine Production
The fermentation of grape must to produce wine is a biologically complex process, carried on by yeasts and malolactic bacteria. The yeasts present in spontaneous fermentation may be divided into two groups, the Saccharomyces yeasts, particularly S. cerevisiae, and the non-Saccharomyces yeasts which include members of the genera Rhodotorula, Pichia, Candida, Debaryomyces, Metschtnikowia, Hansenu...
متن کاملEvaluation of MALDI-TOF Mass Spectrometry for Identification of Yeasts Commonly Found During Environmental Monitoring | Charles River
Introduction An ideal environmental monitoring (EM) program should have the ability to detect and identify all categories of microbes – bacteria, yeasts and molds. The following study focuses on identifying yeasts commonly found during environmental monitoring. Yeasts belong to the kingdom of fungi and are placed in the phyla of Ascomycota and Basidiomycota. They are typically single-celled org...
متن کاملStrategy for Adapting Wine Yeasts for Bioethanol Production
The Saccharomyces cerevisiae wine yeast strains 71B-1122 and K1-V1116 were used to derive strains that could tolerate and produce higher ethanol yields. Respiratory-deficient mutants resistant to 500 microg/mL lycorine were isolated. Two mutants, 71B-1122 YEBr L3 and K1-V1116 YEBr L4, were shown to achieve about 10% and 18% improvement in their glucose-to-ethanol conversion efficiency compared ...
متن کاملOccurrence and Growth of Killer Yeasts during Wine Fermentation.
Sixteen wine fermentations were examined for the presence of killer yeasts. Killer property and sensitivity to killer action were found in isolates of Saccharomyces cerevisiae but not in isolates of Kloeckera, Candida, Hansenula, and Torulaspora spp. Several killer and killer-sensitive strains of S. cerevisiae were differentiated by colony morphology, and this property was used to monitor their...
متن کاملIdentification of uncommon oral yeasts from cancer patients by MALDI-TOF mass spectrometry
BACKGROUND Opportunistic infections due to Candida species occur frequently in cancer patients because of their inherent immunosuppression. The aim of the present study was to investigate the epidemiology of yeast species from the oral cavity of patients during treatment for oncological and haematological malignancies. METHODS MALDI-TOF was performed to identify yeasts isolated from the oral ...
