The mannans of Saccharomyces chevalieri, S. italicus, S. diastaticus, and S. carlsbergensis, were acetolyzed, and the fragments were separated by gel filtration. All gave similar acetolysis fingerprints, which were distinguished from S. cerevisiae by the presence of a pentasaccharide component in addition to the mono-, di-, tri-, and tetrasaccharides. All oligosaccharide fragments were composed...

Yeast species have undergone extensive genome reorganization in their evolutionary history, including variations in chromosome number and large chromosomal rearrangements, such as translocations. To determine directly the contribution of chromosomal translocations to the whole organism's fitness, we devised a strategy to construct in Saccharomyces cerevisiae collinear "evolutionary mimics" of o...

The extent to which the order of genes along chromosomes is conserved between Saccharomyces cerevisiae and related species was studied by analysing data from DNA sequence database. As expected, the extent of gene order conservation decreases with increasing evolutionary distance. About 59% of adjacent gene pairs in Kluyveromyces lactis or K. marxianus are also adjacent in S. cerevisiae, and a f...

This work is a short review of the interactions between oenological yeasts and lactic acid bacteria (LAB), especially Oenococcus oeni, the main species carrying out the malolactic fermentation (MLF). The emphasis has been placed on non-Saccharomyces effects due to their recent increased interest in winemaking. Those interactions are variable, ranging from inhibitory, to neutral and stimulatory ...

the potential of heat inactivated saccharomyces cerevisiae in the bioremoval and reduction ofcr (vi) ions from wastewaters was evaluated in terms of metal uptake in time and at equilibrium, andbiosorption efficiency, by varying ph, biosorbent doses, contact time and temperature, in batch mode. during the sorption process, the heat inactivated biomass of the yeast saccharomyces cerevisiae is cap...

Saccharomyces yeasts degrade sugars to two-carbon components, in particular ethanol, even in the presence of excess oxygen. This characteristic is called the Crabtree effect and is the background for the 'make-accumulate-consume' life strategy, which in natural habitats helps Saccharomyces yeasts to out-compete other microorganisms. A global promoter rewiring in the Saccharomyces cerevisiae lin...

The aim of this study is to investigate the possibility of Saccharomyces cerevisiae as an alternative adsorbent for phenol removal from aqueous solution .The Saccharomyces cerevisiae was characterised by Brunauer Emmett Teller (BET) and Fourier transform (FT-IR). Adsorption properties of Saccharomyces cerevisiae towards phenol were systematically investigated, including pH effect, adsorbent dos...

Lignocellulose wastes are the most abundant residues on surface of earth. This project studies possibility ethanol production from a forestry waste. Wood Gmelina arborea were treated with dillute sulfuric acid to break down lignin component. Fermentation for was done using baker’s yeast (Saccharomyces cerevisiae ATCC 204508/S288c) 120 hours submerged fermentation, and pH, reducing sugar, specif...

Non-Saccharomyces wine yeasts are not only proposed to improve the sensory profile of but also for several distinctive promising features. Among them, biocontrol action at different steps production chain could be a suitable strategy reduce use sulfur dioxide. In this work, activity selected strain Metschnikowia pulcherrima was evaluated as inoculum in cold clarification with aim SO2 and aromat...

Sugar beet molasses is one of the important by products in sugar industry, it dark brown to black colored and rich source various polysaccharides. So, can be used production ethanol by Saccharomyces cerevisiae. Data showed that 2% inoculums size was best all tested for media. Where alcohol 4.6 ml /100 media with economic coefficient 53.7% yield 46.1%. Also, incubation periods were...
