ARS elements of Saccharomyces cerevisiae are the cis-acting sequences required for the initiation of chromosomal DNA replication. Comparisons of the DNA sequences of unrelated ARS elements from different regions of the genome have revealed no significant DNA sequence conservation. We have compared the sequences of seven pairs of homologous ARS elements from two Saccharomyces species, S. cerevis...

Earlier work with a fluorescent aid indicated that flocculent brewer's yeast may have more surface lipids than nonflocculent types. Organic solvents were checked against flocculent Gilliland yeasts. It was found that those reagents which affect "free" lipids had no dispersive action, and those which remove "bound" fats had a powerful dispersive action against such yeasts. There was no indicatio...

An increasing interest in novel wine productions is focused on non-Saccharomyces yeasts due to their potential improving sensory profiles. Although Kluyveromyces marxianus has been originally isolated from grapes and its enzymatic activities are used oenology, rarely it as co-starter. The K. Km L2009 strain characterized here selected a co-starter both at laboratory- winery-scale fermentation. ...

Genetic and physical maps for the 16 chromosomes of Saccharomyces cerevisiae are presented. The genetic map is the result of 40 years of genetic analysis. The physical map was produced from the results of an international systematic sequencing effort. The data for the maps are accessible electronically from the Saccharomyces Genome Database (SGD: http://genome-www.stanford. edu/Saccharomyces/).

Exploitation of the biodiversity native wine yeast is a means modifying sensory characteristics wine. Samples from different regions in China were analysed to screen isolates as potential starter cultures. Through morphological and molecular biological analyses, we found six species, belonging four genera (Hanseniaspora, Saccharomyces, Rhodotorula Metschnikowia). These species subjected stress ...

In this work was evaluated the effect of sequential inoculum Hanseniaspora uvarum AS27 strain and a commercial Saccharomyces cerevisiae yeast on physical–chemical organoleptic features Aglianico, traditional red wine Southern Italy. Four fermentation treatments pilot scale were performed. treatment A, alcoholic spontaneously conducted by indigenous yeasts present in grape must. B C inoculated r...
