About Dyadic International, Inc.

Dyadic International, Inc., is a biotechnology company focused on the efficient large-scale manufacture of proteins for use in human and animal vaccines and therapeutics and for use in non-pharmaceutical applications including food, nutrition, and wellness.

Dyadic’s microbial gene expression and protein production platforms are based on the highly productive and scalable fungus Thermothelomyces heterothallica (formerly Myceliophthora thermophila). Our lead platform, the C1-cell protein production platform, is based on an industrially proven microorganism (named C1), which is currently used to speed development, lower production costs, and potentially improve performance of biologic vaccines and drugs at flexible commercial scales for the human and animal health markets. Dyadic has also developed the Dapibus™ protein production platform to enable the rapid development and large-scale manufacture of low-cost proteins, metabolites, and other biologic products for use in non-pharmaceutical applications, such as food, nutrition, and wellness.

Dyadic is focusing on leveraging its microbial platform technologies for itself and its collaborators in a wide range of applications, including human and animal vaccines, therapeutics, food, nutrition, wellness, and internal biological products.
