Collaborative Arrangement Disclosure [Text Block]	Note 3: Research and Collaboration Agreements, Sublicense Agreements, and Investments in Privately-Held Companies *BDI* On June 30, 2017, the Company entered into a strategic Research Services Agreement (the “RSA”) with Biotechnology Developments for Industry in Pharmaceuticals, S.L.U. (“BDI Pharma”), and a Service Framework Agreement (the “SFA”, and together with the RSA, the “R&D Agreements”), with VLP The Vaccines Company, S.L.U. (“VLPbio”), both of which are subsidiaries of Biotechnology Developments for Industry, S.L., a Spanish biotechnology company (“BDI Holdings” and together with BDI Pharma and VLPbio, “BDI”). The R&D Agreements provide a framework under which the parties will engage in a research and development collaboration encompassing several different projects over approximately a two-year period, with a focus on advancing Dyadic’s proprietary C1 technology in the development of next generation biological vaccines and drugs. Dyadic expects to leverage the BDI team’s previous C1 gene expression and industrial fermentation scale-up and commercialization experience with yeast and filamentous fungi processes to further advance Dyadic’s proprietary C1 technology with the potential to commercialize certain biopharmaceutical product(s). All of the data and any products developed from the funded research projects will be owned by Dyadic. Upon closing of the BDI transaction, the Company paid EUR €1.0 million (the “RSA Initial Payment”) in cash to engage BDI to develop designated C1 based product candidates and further improve the C1 manufacturing process, in consideration of which Dyadic also received a 16.1% equity interest in BDI Holdings and a 3.3% equity interest in VLPbio. BDI is obligated to spend a minimum amount of EUR €936,000 over two years in the conduct of the research and development project under the RSA. If the research and development activities produce a product that is selected for additional development and commercialization, then Dyadic expects to share with BDI a range of between 50% and 75% of the net income from such selected product, depending upon the amount of BDI’s aggregate spend in the development of the selected product, with a minimum aggregate spend by BDI of EUR €1 million for a 50% share and EUR €8.0 million for a 75% share. If BDI does not enter into an agreement with Dyadic for such additional development and commercialization of the selected product, then Dyadic will pay to BDI EUR €1.5 million of the net income from Dyadic’s commercialization, if any, of the selected product. In addition, under the SFA, Dyadic agreed to purchase from BDI at least USD $1.0 million (the “SFA Commitment”) in contract research services specified by Dyadic over two years since the closing of the BDI transaction. The Company has concluded that BDI is not a Variable Interest Entity (“VIE”), because BDI has sufficient equity to finance its activities without additional subordinated financial support and its at-risk equity holders have the characteristics of a controlling financial interest. Additionally, Dyadic is not the primary beneficiary of BDI as Dyadic does not have the power to control or direct the activities of BDI or its operations. As a result, the Company does not consolidate its investments in BDI, and the financial results of BDI are not included in the Company’s consolidated financial results. The Company performed a valuation analysis of the components of the transaction and allocated the consideration based on the relative fair value of each component. As the fair value of BDI equity interest was considered immaterial, the RSA Initial Payment of approximately USD $1.1 million (EUR €1.0 million) was accounted for as a prepaid research and development collaboration payment on our consolidated balance sheet, and both the collaboration payment under the RSA and the SFA Commitment of USD $1.0 million paid by Dyadic were expensed as the related research services were performed by BDI. In June 2019, BDI has completed its services under the RSA and the entire amount of the RSA Initial Payment was expensed. Dyadic had fulfilled its SFA commitment and completed all research projects under the SFA in 2019. On February 18, 2021, the Company entered into a separate service agreement with BDI to perform a research project unrelated to the R&D Agreements. For the three months ended March 31, 2021, approximately $15,000 recorded in the cost of research and development revenue was associated with this new service agreement. *Novovet and Luina Bio* On April 26, 2019, the Company entered into a sub-license agreement (the “Luina Bio Sub-License Agreement”) with Luina Bio Pty Ltd. (“Luina Bio”) and Novovet Pty Ltd (“Novovet”). Under the terms of the Luina Bio Sub-License Agreement, the Company has granted to Novovet, subject to the terms of the license agreement entered into between the Company and Danisco US, Inc. on December 31, 2015, a worldwide sub-license to certain patent rights and know-how related to Dyadic’s proprietary C1 gene expression platform for the exclusive and sole purpose of commercializing certain targeted antigen and biological products for the prevention and treatment of various ailments for companion animals. In consideration of the license granted pursuant to the Luina Bio Sub-License Agreement, Dyadic received a 20% equity interest in Novovet (“Novovet Up-Front Consideration”) in accordance with the terms of Novovet’s Shareholder Agreement, and will receive a percentage of royalties on future net sales and non-sales revenue, if any, which incorporates Dyadic’s proprietary C1 gene expression platform. The Company evaluated the nature of its equity interest investment in Novovet and determined that Novovet is a VIE, because Novovet does not have sufficient equity to finance its activities without additional financial support from third party investors or lenders. However, the Company is not the primary beneficiary of Novovet as Dyadic does not have the power to control or direct the activities of Novovet that most significantly impact the VIE. As a result, the Company will not consolidate its investment in Novovet, but account for under the equity method investment, given that it has the ability to exercise significant influence, but not control, over Novovet. To date Novovet has not raised the capital required to move this opportunity forward, and therefore, the Company has not transferred its C1 technology to Novovet. Therefore, the Novovet Up-Front Consideration received under the Luina Bio Sub-License Agreement, in the form of a 20% equity interest in Novovet, does not yet meet the revenue recognition criteria under ASC 606. The Company will account for its investment in Novovet and the related income under the equity method of accounting, once the transfer of its C1 technology is completed and Novovet receives adequate financing required to commence its research and development activities. The Company intends to terminate the Luina Bio Sub-License Agreement in 2021 should Novovet be unable to raise the required funding. *Alphazyme* On May 5, 2019, the Company entered into a sub-license agreement (the “Alphazyme Sub-License Agreement”) with Alphazyme, LLC (“Alphazyme”). Under the terms of the Alphazyme Sub-License Agreement, the Company has granted to Alphazyme, subject to the terms of the license agreement entered into between the Company and Danisco US, Inc. on December 31, 2015, a sub-license to certain patent rights and know-how related to Dyadic’s proprietary C1 gene expression platform for the purpose of commercializing certain pharmaceutical products that are used as reagents to catalyze a chemical reaction to detect, measure, or be used as a process intermediate to produce a nucleic acid as a therapeutic or diagnostic agent. On June 24, 2020, the Company entered into an Amended and Restated Non-Exclusive Sub-License Agreement (the “Amended Sub-License Agreement”) with Alphazyme. Pursuant to the Amended Sub-License Agreement and in consideration of Dyadic’s transfer of its C1 technology, Alphazyme issued 2.50% of the Class A shares of Alphazyme to Dyadic, and Dyadic became a party to the Alphazyme Limited Liability Company Agreement pursuant to which the Company has agreed to certain customary rights, covenants and obligations. In addition, and subject to achieving certain milestones, Alphazyme is obligated to pay a potential milestone payment and royalties, based on net sales, if any, which incorporate Dyadic’s proprietary C1 gene expression platform. On December 1, 2020, the Company entered into an Amended and Restated Limited Liability Company Agreement with Alphazyme (the “Amended Alphazyme LLC Agreement”) was entered into. Under the Amended Alphazyme LLC Agreement, Alphazyme obtained an additional capital contribution and Dyadic’s ownership was diluted to 1.99%. The Company evaluated the nature of its equity interest investment in Alphazyme and determined that Alphazyme is a VIE due to the capital structure of the entity. However, the Company is not the primary beneficiary of Alphazyme as Dyadic does not have the power to control or direct the activities of Alphazyme that most significantly impact the VIE. As a result, the Company does not consolidate its investment in Alphazyme. The Company reports its investment in Alphazyme under the cost method of accounting, given that it does not have the ability to exercise significant influence or control, For the year ended December 31, 2020, the Company recorded a gain of $284,709 from its investment in Alphazyme as a result of a third-party additional capital contribution obtained by Alphazyme. As of March31, 2021, the Company does not consider its investment in Alphazyme to be impaired. *IDBiologics, Inc.* On July 8, 2020, the Company entered into a Common Stock Purchase Agreement (the “IDBiologics Agreement”) with IDBiologics, Inc (“IDBiologics”). IDBiologics is a private biotechnology company focused on the development of human monoclonal antibodies for the treatment and prevention of serious infectious diseases. The Company was founded in 2017 and seeded by Vanderbilt University Medical Center in response to the repeated threats of epidemics around the world, including Ebola in West Africa and Zika in the Americas. IDBiologics is developing a portfolio of monoclonal antibodies against SARS-CoV-2, influenza and Zika viruses. Under the term of the IDBiologics Agreement, Dyadic agreed to receive 129,611 shares of IDBiologics’ common stock, which represent 0.37% of IDBiologics’ outstanding equity, in exchange for the services to be provided by Dyadic. Such services include the use of Dyadic’s C1 technology to express a SARS-CoV-2 monoclonal antibody which IDBiologics licensed from the Vanderbilt Vaccine Center. The shares of common stock of IDBiologics vested 50% upon the signing of the IDBiologics Agreement, 25% will vest upon the completion of Step 3 of a feasibility study required by the IDBiologics Agreement, and 25% will vest at the end of the project. The Company evaluated the nature of its equity interest in IDBiologics and determined that IDBiologics is a VIE due to the capital structure of the entity. However, the Company is not the primary beneficiary of IDBiologics as Dyadic does not have the power to control or direct the activities of IDBiologics that most significantly impact the VIE. As a result, the Company does not consolidate its investment in IDBiologics. Upon receipt its shares, Dyadic will account for the equity interest in IDBiologics under the cost method. No revenue from the IDBiologics Agreement was recorded during the three months ended March 31, 2021, because the amount of consideration received was immaterial.
