Dyadic International, Inc. is a global biotechnology company focused on building innovative microbial protein production platforms to address the growing demand for global protein bioproduction utilizing its advanced microbial platforms to develop and manufacture prophylactic, therapeutic, and nutritional biopharmaceutical products for human and animal health and wellness. Dyadic’s gene expression and protein production platforms are based on the highly productive and scalable fungus Thermothelomyces heterothallica (formerly Myceliophthora thermophila). Our lead technology, 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 improve performance of biologic vaccines and drugs at flexible commercial scales for the human and animal health markets.
