[A new yeast strain for brewery: properties and advantages]

Area of Science:

• Food Science and Technology
• Microbiology
• Biotechnology

Background:

• Beer quality is significantly influenced by yeast strains, with off-flavors being a persistent challenge in production.
• Optimizing yeast performance is crucial for developing high-quality beer and novel brewery products.

Purpose of the Study:

• To develop and characterize a novel industrial yeast Saccharomyces cerevisiae strain with superior technological properties for brewing applications.
• To assess the strain's efficacy in fermentation, sulfur compound production, and diacetyl reduction.

Main Methods:

• Isolation and characterization of an industrial yeast Saccharomyces cerevisiae strain.
• Evaluation of fermentation efficiency and key metabolite production (sulfur compounds, diacetyl).
• Assessment of the strain's potential for developing new beer and nonalcoholic products.

Main Results:

• The developed Saccharomyces cerevisiae strain demonstrated efficient fermentation capabilities.
• The strain exhibited reduced production of sulfur hydrate and a high diacetyl reduction rate.
• These properties facilitate the creation of new beer brands and nonalcoholic beverages.

Conclusions:

• The novel industrial yeast strain possesses advantageous technological properties for the brewing industry.
• The strain's characteristics enable the development of improved beer quality and diverse new products.
• Commercialization and patenting underscore the strain's industrial significance and potential.
