Vancouver, Canada — Renaissance BioScience Corp., a main world-wide bioengineering company, is pleased to officially announce the publication of a landmark paper on lager yeast progress in the February 2021 challenge of Applied and Environmental Microbiology (Volume 87, Difficulty 3). “Industrially Relevant De Novo Lager Yeast Hybrids with a One of a kind Genome Architecture: Development and Characterization,” by Turgeon et al, explains how the Renaissance investigation crew designed an modern solution in making novel non-GMO lager yeast strains that are instantly suitable for lager beer manufacturing, and which will support broaden the range of industrial lager beer strains for both of those key worldwide beer producers and lesser craft breweries.
For hundreds of many years, lager beer has been developed working with strains from two related lager yeast varieties: Group I and Team II. Although these groups are genetically various, they create very equivalent flavour and aroma profiles, and therefore enjoy a position in the absence of diversity in business lager beer. To day, ways aimed at generating new lager yeast have produced strains that have undesirable brewing traits that render them commercially unviable. This novel strategy circumvents the difficulty and lets for the creation of new lager strains that are right appropriate for lager creation. The paper proposes that yeast created working with this novel solution be labeled as a third team of lager strains (Team III).
Renaissance BioScience CEO, Dr. John Husnik, reviews: “This Renaissance accomplishment is one particular of the most sensible improvements in lager yeast strain growth. Our paper outlines how this advance was produced and, importantly, describes the likely to produce quite a few distinctive novel lager yeast strains, and also to fantastic-tune and greatly enhance a lot of latest proprietary strains utilized by beer producers all over the planet. This yeast technology is prepared to start out industrial usage and programs. Congratulations to our crew on this thrilling advance. We’re about to enter a complete new world of lager beer innovation.”
Zachari Turgeon, Principal Scientist and the paper’s direct writer, responses: “Our specialist analysis and advancement group has designed an stylish and really rigorous tactic to producing lager strains that has substantial prospective to broaden flavour profiles and boost the industrial effectiveness of beermaking. In addition, the Renaissance system method could be merged with our patented hydrogen sulfide-protecting against engineering to minimize or even remove the off-aroma hydrogen sulfide, a typical problem for lager beermakers just about everywhere, and this provides patent defense for any lager yeast innovations developed with our technological innovation. We seem ahead to conversations with beer producers and grasp brewers about our paper and the Renaissance strategy to yeast pressure advancements.”
The Renaissance strategy was to breed the S. eubayanus subgenome from industrial lager strains and hybridize them to unique ale strains, removing the want to breed undomesticated, wild S. eubayanus strains. This produces a amount of beneficial results:
None of the negative attributes affiliated with utilizing wild S. eubayanus are current.The genomic composition of the new Renaissance strains made is exclusive compared to all identified lager yeast — the authors suggest that these novel strains type a third team of lager yeast (Group III). The new Renaissance strains now have a broader temperature tolerance range this can maximize their employs for distinctive kinds of beer, as nicely as strengthen propagation and the producing of the yeast.
Renaissance’s R&D workforce can considerably raise the diversity of lager yeast by making use of a large wide variety of diverse parental strains, major to optimization of lager yeast effectiveness, an increase in the aroma and flavour diversity of lager strains, and the elimination of off-aromas.The Renaissance improvement strategy is solely non-GMO, relying solely on yeast’s normal sexual copy.
Jessica Swanson, Direct Improvement Scientist and Beverage Unit Manager, provides: “The Renaissance approach in making commercially applicable and really beneficial lager strains could also be blended with yeast advances and systems earlier formulated by other scientists to make secured enhanced strains. Most importantly, all of these innovation possibilities will have substantial benefits for beer buyers all around the world.”
