Saccharomyces kudriavzevii and Saccharomyces uvarum differ from Saccharomyces 1
12 Higher alcohols and acetate esters are important flavour and aroma components in the food 13 industry. In alcoholic beverages these compounds are produced by yeast during fermentation. 14 Although S. cerevisiae is one of the most extensively used species, other species of the 15 Saccharomyces genus have become common in fermentation processes. This study analyses 16 and compares the producti...
متن کاملSaccharomyces and Non-Saccharomyces Starter Yeasts
This chapter describes the importance of yeast in beer fermentation. Initially, the differences between Saccharomyces cerevisiae and Saccharomyces pastorianus in the production of “ale” and “lager” beers are analyzed. Then, the relationships between beer nutrients and yeast growth are discussed, with special emphasis on the production of the flavor compounds. The impact of the wort composition ...
متن کاملStructure and immunochemistry of the cell wall mannans from Saccharomyces chevalieri, Saccharomyces italicus, Saccharomyces diastaticus, and Saccharomyces carlsbergensis.
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...
متن کاملSaccharomyces cerevisiae
Yeast prions are infectious proteins that spread exclusively by mating. The frequency of prions in the wild therefore largely reflects the rate of spread by mating counterbalanced by prion growth slowing effects in the host. We recently showed that the frequency of outcross mating is about 1% of mitotic doublings with 23-46% of total matings being outcrosses. These findings imply that even the ...
متن کاملMating pheromones of Saccharomyces kluyveri: pheromone interactions between Saccharomyces kluyveri and Saccharomyces cerevisiae.
Saccharomyces kluyveri is a heterothallic yeast with two allelic mating types denoted as a-k and alpha-k by analogy with Saccharomyces cerevisiae and from the work described here. S. kluyveri produces mating pheromones analogous to those of S. cerevisiae, but which appear to have different specificity. S. kluyveri thus differs from S. cerevisiae, Hansenula wingei, and Schizosaccharomyces pombe ...
