Microbial dynamics in industrial-scale wine fermentation employing Hanseniaspora uvarum β-glucosidase-producer strain. [PDF]
The use of non-Saccharomyces yeast strains in winemaking is becoming a common trend. In fact, consumers are demanding new and healthier styles of wine. On the other hand, these strains are a challenge for the starting process due to winery-resident strains, especially with regard to industrial-scale fermentations.

The Role of Glucose-6-phosphate Dehydrogenase in the Wine Yeast Hanseniaspora uvarum. [PDF]
Hanseniaspora uvarum is the predominant yeast species in the majority of wine fermentations, which has only recently become amenable to directed genetic manipulation. The genetics and metabolism of H. uvarum have been poorly studied as compared to other yeasts of biotechnological importance.

PCR-based gene targeting in Hanseniaspora uvarum
Abstract Lack of gene-function analyses tools limits studying the biology of Hanseniaspora uvarum, one of the most abundant yeasts on grapes and in must. We investigated a rapid PCR-based gene targeting approach for one-step gene replacement in this diploid yeast.

Volatile compounds contribution of Hanseniaspora guilliermondii and Hanseniaspora uvarum during red wine vinifications [PDF]
This work aims to investigate the contribution of a selected non-Saccharomyces yeast species, Hanseniaspora guilliermondii, to higher alcohols, esters, fatty acids and heavy sulphur compounds composition of red wine. Red grape must vinifications of 100 l were performed and an inoculated fermentation with H.

Volatile organic compounds of Hanseniaspora uvarum increase strawberry fruit flavor and defense during cold storage. [PDF]
AbstractVolatile organic compounds (VOCs) of antagonistic yeasts are considered as environmental safe fumigants to promote the resistance and quality of strawberry (Fragaria ananassa). By GC‐MS assays, VOCs of Hanseniaspora uvarum (H. uvarum) fumigated strawberry fruit showed increased contents of methyl caproate (5.8%), methyl octanoate (5.1%), and ...

Screening of Hanseniaspora Strains for the Production of Enzymes with Potential Interest for Winemaking [PDF]
Some non-Saccharomyces yeasts, including Hanseniaspora, participate in the first stages of wine fermentation. Besides their importance in the wine production process some of these yeasts have been described to be potential producers of hydrolytic enzymes

Influence des produits de traitement de la vigne sur la microflore levurienne (*)
Parmi les produits de traitement essayés à la vigne en 1975, c'est l'Euparène qui modifie le plus profondément la flore des levures. Pendant les 17 jours de contrôle de la fermentation, cette flore a été composée, en présence d'Euparène, de 57 p.
