Effect of preharvest application of Hanseniaspora uvarum on postharvest diseases in strawberries

Postharvest Biology and Technology, 2015
Abstract This study was conducted to evaluate the efficacy of preharvest applications of Hanseniaspora uvarum against postharvest mold decay of strawberry (Fragaria ananassa) fruit and quality maintenance during storage at 2 ± 1 °C and 90–95% RH.

Glucose metabolism, enzymic analysis and product formation in chemostat culture of Hanseniaspora uvarum

Yeast, 1995
AbstractThe physiology of Hanseniaspora uvarum K5 was studied in glucose‐limited chemostat cultures and upon glucose pulse. Up to a dilution rate of 0·28 h−1, glucose was completely metabolized in biomass and CO2. Above this value, increase in the dilution rate was accompanied by sequential production of metabolites (glycerol, acetate and ethanol) and ...

The nucleotide sequence and initial characterization of pyruvate decarboxylase from the yeast Hanseniaspora uvarum

Yeast, 1994
AbstractWe have isolated a pyruvate decarboxylase (PDC) gene from the yeast Hanseniaspora uvarum using the Saccharomyces cerevisiae PDC1 gene as a probe. The nucleotide sequence of this gene was determined and compared to PDC genes from yeast and other organisms. The H. uvarum PDC gene is more than 70% identical to the S.

Proteomics profile of Hanseniaspora uvarum enhanced with trehalose involved in the biocontrol efficacy of grape berry

Food Chemistry, 2019
This present study tested the extent to which 2% w/v trehalose enhanced the proteins expression profile of Hanseniaspora uvarum Y3. Furthermore, it explored the relative gene expression of stilbene synthase (StSy), one of the vital defense-related genes found in the skin of grapes.

Killer toxin producing strains of the yeasts Hanseniaspora uvarum and Pichia kluyveri

Archives of Microbiology, 1988
By heat treatment killer strains of the type K1 of Saccharomyces cerevisiae that are known to harbour dsRNA plasmids were completely cured, whereas only a small fraction of the clones of the killer type K2 had lost the dsRNA dependent killer character. The K2 killers but not the strains of killer type K1 were easily cured by cycloheximide.

Viability of Hanseniaspora uvarum yeast preserved by lyophilization and cryopreservation.

Yeast (Chichester, England), 2016
Hanseniaspora yeasts are known to produce volatile compounds that give fruity aromas in wine and fermented fruit. This study aimed to verify the feasibility of the Hanseniaspora uvarum strain that had been isolated and identified during a previous study and preserved by lyophilization and freezing at -80 °C (cryopreservation).

Inhibitory activity of tea polyphenol and Hanseniaspora uvarum against Botrytis cinerea infections [PDF]

Letters in Applied Microbiology, 2010
To investigate the effect of tea polyphenol (TP) and Hanseniaspora uvarum alone or in combination against Botrytis cinerea in grapes and to evaluate the possible mechanisms involved.TP alone was effective in controlling grey mould in grape at all concentrations. TP at 0.5 and 1.0% in combination with H.

Unique double-stranded RNAs responsible for the anti-Candida activity of the yeast Hanseniaspora uvarum

Journal of Virology, 1997
Killer strains of the yeast Hanseniaspora uvarum contain cytoplasmic double-stranded RNAs (dsRNAs) of 4.7-kbp L and 1.0-kbp M species, which were shown to be separately packaged into icosahedral virus-like particles exhibiting RNA-dependent RNA polymerase activity. The L genome of the H.

Transcriptomic responses of Saccharomyces cerevisiae and Hanseniaspora uvarum during separated co-fermentation

World Journal of Microbiology and Biotechnology
Hanseniaspora uvarum is a predominant yeast species in vineyards and some strains demonstrate oenological potential by enhancing the aroma complexity and reducing the content of volatile acid and ethanol in wine. H. uvarum kept in our lab could improve the flavor and quality of wine when co-fermented with Saccharomyces cerevisiae, but its growth was ...

Influence of oxygen limitation on glucose metabolism in Hanseniaspora uvarum K5 grown in chemostat

Biotechnology Letters, 1995
Growth and metabolite formation were studied as a function of oxygen feed rate, in glucose-limited chemostat cultures of Hanseniaspora uvarum K5 at a dilution rate of 0.26 h−1. Alcoholic fermentation occured at an oxygen feed rate of 80 mmol.l−1.h−1 . Below this value, pyruvate decarboxylase and alcohol dehydrogenase were present at high levels.
