We also made interspecific hybrids between Saccharomyces cerevisiae and Saccharomyces bayanus var. uvarum strains and verified their hybrid origin with karyotypes and MET2 PCR-RFLP analysis. As compared to the parents, some hybrids could release high amounts of volatile thiols from the S-cysteine conjugate precursor without producing excessive amounts of β-phenylethyl alcohol and its acetate. One hybrid was retained for industrial production under a dry form and successfully compared with Saccharomyces cerevisiae strains in experimental tests in different cellars.

Url1.: https://en.wikipedia.org/wiki/Ascomycota SYSTEMATICS OF DIVISION ASCOMYCOTA 1 Group: Plectomycetes Plectomycetes is an artificial group of Ascomycota and it originally contained all Ascomycete fungi which produce their asci within a cleistothecium. Plectomycetes can be defined by the following set of characters; Cleistothecium or gymnothecium is usually present, ascogenous hyphae are usually not conspicuous, asci are scattered throughout the cleistothecium, asci are mostly globose and thin-walled, and the ascospores are released passively after disintegration of the ascus wall, not by active discharge, ascospores are small, unicellular and usually spherical or ovoid, conidia are commonly produced from phialides or as arthroconidia. Class: Eurotiomycetes Most members of the class produce an enclosed structure cleistothecium within which they produce their spores. It contains 10 order, 27 families 280 genus and about 3400 species. Order: Onygenales Onygenales members are able to digest keratin and because of this have become dominant organisms in environments where keratin is available. The most members have colorless cleistothecia and ascospores. The spherical to egg-shaped asci are always uniformly packed in the centrum and may be dispersed among hyphal elements. The ascospores are always single-celled (example: Chrysosporium, Microsporum and Trichophyton). Order: Eurotiales Most members of the order have phialidic asexual stages belonging to the genera Aspergillus and Penicillium or, less commonly, to Paecilomyces or even simpler types. Rarely there is no anamorph at all. -

Kotseridis3 1 Innovino, Applied Research for Wine, Pallini, Athens 2 Societ´ e´ Industrielle Lesaffre, Division Fermentis, France 3 Laboratory of Enology, Department of Food Science & Human Nutrition, Agricultural University, Athens Abstract. Enhancing flavors and/or improving fermentation parameters through the use of different species of yeast strains is nowadays a frequent challenge in winemaking research, especially for aromatic varieties such as Sauvignon Blanc. In this work, the aim was to focus on the impact of a species not already studied in wine: Saccharomyces pastorianus. Twenty-two fermentations were conducted on a Sauvignon Blanc must by addition of different strains and mixtures of them by using two different inoculation temperatures. The must was inoculated in cold condition with two similar mixtures of S. pastorianus 1 or 2 (70%) and S. bayanus (30%), with S. pastorianus 1 or 2 alone, with the correspondent S. bayanus alone and with two other S. cerevisiae 1 and 2 alone as well. For classic condition, the must was inoculated with only one mixture S. pastorianus 1 (70%) / S. bayanus (30%), and respectively with S. pastorianus 1, S. bayanus and S. cerevisiae 2 alone. Samples were taken all along the fermentations for both conditions in order to check chemical and microbial analyses as well as yeast implantations. -
Novel Non-Cerevisiae Saccharomyces Yeast Species Used in Beer and Alcoholic Beverage Fermentations
fermentation Review Novel Non-Cerevisiae Saccharomyces Yeast Species Used in Beer and Alcoholic Beverage Fermentations James Bruner * and Glen Fox * Food Science and Technology, University of California, Davis, CA 95616, USA * Correspondence: [email protected] (J.B.); [email protected] (G.F.) Received: 28 October 2020; Accepted: 22 November 2020; Published: 24 November 2020 Abstract: A great deal of research in the alcoholic beverage industry was done on non-Saccharomyces yeast strains in recent years. The increase in research interest could be attributed to the changing of consumer tastes and the search for new beer sensory experiences, as well as the rise in popularity of mixed-fermentation beers. The search for unique flavors and aromas, such as the higher alcohols and esters, polyfunctional thiols, lactones and furanones, and terpenoids that produce fruity and floral notes led to the use of non-cerevisiae Saccharomyces species in the fermentation process. Additionally, a desire to invoke new technologies and techniques for making alcoholic beverages also led to the use of new and novel yeast species. Among them, one of the most widely used non-cerevisiae strains is S. pastorianus, which was used in the production of lager beer for centuries. The goal of this review is to focus on some of the more distinct species, such as those species of Saccharomyces sensu stricto yeasts: S. kudriavzevii, S. paradoxus, S. mikatae, S. uvarum, and S. bayanus. In addition, this review discusses other Saccharomyces spp. that were used in alcoholic fermentation. Most importantly, the factors professional brewers might consider when selecting a strain of yeast for fermentation, are reviewed herein. -
Saccharomyces Cerevisiae in the Production of Fermented Beverages
beverages Review Saccharomyces cerevisiae in the Production of Fermented Beverages Graeme M Walker 1,* and Graham G Stewart 2 1 Abertay University, Dundee, Scotland DD1 1HG, UK 2 Heriot-Watt University, Edinburgh, Scotland EH14 4AS, UK; [email protected] * Correspondence: [email protected]; Tel.: +44-1382-308658 Academic Editor: Edgar Chambers IV Received: 20 October 2016; Accepted: 11 November 2016; Published: 17 November 2016 Abstract: Alcoholic beverages are produced following the fermentation of sugars by yeasts, mainly (but not exclusively) strains of the species, Saccharomyces cerevisiae. The sugary starting materials may emanate from cereal starches (which require enzymatic pre-hydrolysis) in the case of beers and whiskies, sucrose-rich plants (molasses or sugar juice from sugarcane) in the case of rums, or from fruits (which do not require pre-hydrolysis) in the case of wines and brandies. In the presence of sugars, together with other essential nutrients such as amino acids, minerals and vitamins, S. cerevisiae will conduct fermentative metabolism to ethanol and carbon dioxide (as the primary fermentation metabolites) as the cells strive to make energy and regenerate the coenzyme NAD+ under anaerobic conditions. Yeasts will also produce numerous secondary metabolites which act as important beverage flavour congeners, including higher alcohols, esters, carbonyls and sulphur compounds. These are very important in dictating the final flavour and aroma characteristics of beverages such as beer and wine, but also in distilled beverages such as whisky, rum and brandy. Therefore, yeasts are of vital importance in providing the alcohol content and the sensory profiles of such beverages. This Introductory Chapter reviews, in general, the growth, physiology and metabolism of S. -
