Comprehensive survey of kombucha microbial communities of diverse origins and fermentation practices

Anne Friedrich, Olivier Courot, Joseph Schacherer, Claudine Bleykasten

Kombucha is a unique, naturally fermented sweetened tea produced for thousands of years, relying on a symbiotic microbiota in a floating biofilm, used for successive fermentations. The microbial communities consist of yeast and bacteria species, distributed across two phases: the liquid and …

Contrasting Genomic Evolution Between Domesticated and Wild Kluyveromyces lactis Yeast Populations

Anne Friedrich, Jean-Sébastien Gounot, Andreas Tsouris, Claudine Bleykasten et autres

The process of domestication has variable consequences on genome evolution leading to different phenotypic signatures. Access to the complete genome sequences of a large number of individuals makes it possible to explore the different facets of this domestication process. Here, we sought …

The complete genome of Blastobotrys (Arxula) adeninivorans LS3 - a yeast of biotechnological interest

Gotthard Kunze, Claude M. Gaillardin, Ma¿gorzata Czernicka, Pascal Durrens et autres

BACKGROUND: The industrially important yeast Blastobotrys (Arxula) adeninivorans is an asexual hemiascomycete phylogenetically very distant from Saccharomyces cerevisiae. Its unusual metabolic flexibility allows it to use a wide range of carbon and nitrogen sources, while being thermotolerant, xerotolerant and osmotolerant. RESULTS: The …

Pichia sorbitophila, an Interspecies Yeast Hybrid, Reveals Early Steps of Genome Resolution After Polyploidization

Véronique Leh Louis, Laurence Despons, Anne Friedrich, Tiphaine C. Martin et autres

Polyploidization is an important process in the evolution of eukaryotic genomes, but ensuing molecular mechanisms remain to be clarified. Autopolyploidization or whole-genome duplication events frequently are resolved in resulting lineages by the loss of single genes from most duplicated pairs, causing transient …

Comparative genomics of protoploid Saccharomycetaceae

Jean‐Luc Souciet, Bernard Dujon, Claude M. Gaillardin, Mark Johnston et autres

Our knowledge of yeast genomes remains largely dominated by the extensive studies on Saccharomyces cerevisiae and the consequences of its ancestral duplication, leaving the evolution of the entire class of hemiascomycetes only partly explored. We concentrate here on five species of Saccharomycetaceae, …

Beet necrotic yellow vein virus 42 kDa triple gene block protein binds nucleic acid in vitro

Claudine Bleykasten, David Gilmer, H. Guilley, K. E. RICHARDS et autres

The triple gene block (TGB) of beet necrotic yellow vein virus RNA 2 is required for cell-to-cell movement of the virus RNA. The protein P42 encoded by the 5'-proximal gene of the TGB has consensus sequence motifs characteristic of an ATP/GTP-dependent helicase. …
