We are seeking contributions to fund the Super Yeast Creation Project, a research project conducted jointly by several laboratories at the University of Tokyo, in which AI techniques (such as deep learning) will be used to enable advanced methods for the directed evolution of yeast. The ultimate goal of the project is to select and cultivate yeast strains that are outstanding in terms of their efficiency and contribution to the flavors of fermented foods, such as bread, miso, soy sauce, beer, wine, and sake, as well as other novel products. Although the theme of our research project is to create "Super Yeasts" for the production of exceptional fermented foods, the advanced AI-enabled directed evolution techniques that we will develop could also be used towards other achievements, such as Super Yeast-based pharmaceutical (e.g. insulin) and biofuel (e.g. bioethanol) production.
With conventional research funding sources, pursuing bottom-up research born from the free ideas of researchers has become difficult due to various constraints, such as heavy administrative work or requirements that focus on short-term achievements. As a result, the scientific community overall lacks support that incentivizes long-term perspectives and the pursuit of highly challenging research. In this project, crowd funding will enable a strong, interdisciplinary team of scientists to work on research themes that are difficult to carry out under conventional research funding. Our goal is to return our research results to society. We want you to join us.
Yeast, a member of the fungi kingdom known as the "Mother of Fermentation", is a microorganism used to make fermented foods such as bread, miso, soy sauce, beer, wine, and sake. It is one of the most widely-used microorganisms for industrial purposes, and at least one use should be familiar: when yeast consumes glucose, it produces alcohol. There are many variants of yeast (with different sizes, shapes, etc.), and their differences are important to consider when making fermented foods. The physiology of yeast can be evaluated via their morphology (structural traits), and by using this information, it is possible to predict the yeast's effect on fermentation. Professor Yoshikazu Ohya of the Graduate School of Frontier Sciences at the University of Tokyo has been researching this relationship between yeast morphology and fermentation and brewing for more than 30 years. In 2019, he discovered that genome editing and morphological analysis are highly important for the breeding of sake yeast. Super Yeast are yeast created by AI-enabled directed evolution that have exceptional morphologies to produce chosen fermented foods. For example, we expect that Super Yeast can be used to make extremely delicious bread, miso, soy sauce, beer, wine, and sake. Furthermore, there could be currently unknown sake styles which could be created by using new Super Yeast. Finally, we expect that Super Yeast could be used to address global food problems by dramatically improving the production efficiency of fermented foods.

Professor Keisuke Goda et al. of the Graduate School of Science at the University of Tokyo successfully developed in 2018 an innovative intelligent (i.e. AI-enabled) image-activated cell sorting (IACS) technology (published in Cell in 2018), which can enable new methods for performing directed evolution, a technique which received the Nobel Prize in Chemistry in 2018. In directed evolution, the functionality of specific biomolecules, produced by bio-organisms, is improved by selectively breeding the best performing organisms across several successive generations of life. Each generation contains a diverse palette of random genetic mutations, and selection of the best of them harnesses the natural process of evolution for scientific and industrial advancement. Through directed evolution, it should be possible to create Super Yeasts that produce fermented foods, such as bread, miso, soy sauce, beer, wine, and sake, that have exceptional taste. Professor Yoshikazu Ohya, a yeast expert, has spent years observing and analyzing different yeast mutants with specific morphologies from a wide variety of yeast cell populations. Typically this analysis is done by looking at the yeast one by one using a microscope, a highly inefficient process with a high cost of time and effort. However, the state-of-the-art intelligent IACS can dramatically improve the accuracy and speed of this process (by more than 1000 times), without relying on human labor or experience. This technology makes it possible to quickly and accurately discover morphologically specific cells among huge cell populations. Using IACS, our ability to find and isolate outstanding cells is exceptional, allowing us to complete in half a day an amount of work that would have taken have a year to finish under traditional manual methods.

During the Japanese 2020 fiscal year, Professor Goda will develop a novel AI-enabled directed evolution method in cooperation with Professor Sotaro Uemura of the Graduate School of Science at the University of Tokyo. In fiscal year 2021, Professors Goda and Ohya will apply this new techonoly to the directed evolution of yeast based morphological information. In the 2022 fiscal year, project researchers will analyze the isolated Super Yeast and their gene functions. In the 2023 fiscal year, we plan to develop exceptionally flavored alcohols by using the Super Yeast strains we will have developed. Following that, we plan to create a venture company built around these concepts. The creation of new foods and richer flavors, enabled by our Super Yeast and in cooperation with major food companies, is expected to produce tremendous economic results. The theme of this project is to create Super Yeast and apply it to the creation of super fermented foods, but the AI-enabled directed evolution method we develop could also be applied to other major issues. New yeasts might be developed to tackle the production of pharmaceuticals, such as insulin, or biofuels, such as bioethanol. All of these various applications are worthy goals which we hope to achieve in the future.
The research team undertaking this project consists of members of the Goda Laboratory (Department of Chemistry, Graduate School of Science, the University of Tokyo), the Ohya Laboratory (Department of Advanced Life Sciences, Graduate School of Frontier Sciences, the University of Tokyo), and the Uemura Laboratory (Department of Biological Sciences, Graduate School of Science, The University of Tokyo), led by Professors Goda, Ohya, and Uemura, respectively. The project has additional significance by bringing together an international team of researchers, including students and young researchers from around the world, who will actively cooperate on this project and experience together the excitement of undertaking challenging research.
