GlobalYeast is a Belgian-Brazilian biotechnology startup focused on developing and deploying products and solutions for the fermentation industry. Base operations are strategically placed in both countries to better serve our clients globally. Our unique insight into fermentation processes is based on our strong knowledge of yeast metabolism and genetics and on applied research at the frontier of these sciences. Combined with our industrial know-how from years of experience in the Brazilian ethanol industry and multiple collaborations with yeast and fermentation industries world-wide, we are well equipped to understand our client’s needs and to deliver tangible results

GlobalYeast provides unique products and services to key markets of the bio-based economy. We develop and supply superior industrial yeast strains and advanced industrial fermentation services for three main markets:

First Generation Bioethanol
Second Generation Bioethanol
  Bio-Based Chemicals From Renewable Resources

GlobalYeast’s science and technology platform includes the proprietary strain Excellulor™ is suitable for second generation ethanol plants and ferments C5 sugars in concentrated and undetoxified lignocellulose hydrolysates. Platform technology of polygenic analysis allows rapid and complex gene identification and is based on strong IP and existing patent applications.


GlobalYeast  was formed by an investment consortium of Brazilian and Belgian shareholders.

Collaboration Network

COPPE is a highly respected institution in Latin America, known for its important contributions to research and education in many fields of engineering. Boasting thousands of articles published and over a hundred patents filed, it is a reference not only in academia but also with the industry through research agreements and contracts with many of Brazil’s major industry players as well as multinationals. GlobalYeast counts on the expertise and knowledge of one the most academically thriving research groups of this institution for the development of its solutions for the fermentation industry.
Situated in Belgium, in the heart of Western Europe, KU Leuven has been a center of learning for nearly six centuries. Today, it is Belgium’s largest university and, founded in 1425, one of the oldest and most renowned universities in Europe. As a leading European research university and co-founder of the League of European Research Universities (LERU), KU Leuven offers a wide variety of international master’s programmes, all supported by high-quality, innovative, interdisciplinary research. KU Leuven is a research-intensive, internationally oriented university that carries out both fundamental and applied research. It is strongly inter- and multidisciplinary in focus and strives for international excellence. To this end, KU Leuven works together actively with its research partners at home and abroad.


Advanced Industrial Fermentation Service
GlobalYeast Advanced Industrial Fermentation Services are capable of describing the process behavior in real-time based on the thorough understanding of cell metabolism and polygenic behavior combined with the evaluation of process inputs. Our services are able to follow-up in real time fermentation performance enhancing operational decision making and leveraging yield and productivity. Our solution BioCal® provides monitoring of sugar conversion to ethanol and employs this information to design knowledge-based decision strategies for process optimization.
Superior Industrial Yeast Strain
A robust and knowledge-based methodology allows the design of Superior Industrial Yeast Strains based on existing industrial strains of Saccharomyces cerevisiae. GlobalYeast provides tailored yeast strains designed for optimization of E1G production or designed for the E2G challenge: converting C5 sugar streams in the most economical way with high yield and productivity in undetoxified lignocellulose hydrolysates. Polygenic Analysis, a core technology developed in the lab is used to identify causative alleles defining superior traits of industrial importance. The causative alleles are used to enhance in a highly specific and predictable manner the performance of industrial yeast strains. In our innovation pipeline, we develop superior industrial yeast strains for multiple stress tolerance characteristics, high ethanol titers, multiple substrate utilization, reduced by-product formation and other traits of industrial importance. Our polygenic analysis platform and know-how in metabolic engineering and other technologies for yeast strain development are also used for the generation of superior cell factory yeasts for the production of bio-based chemicals with various renewable resources and waste streams.
