Dyadic to Present at BIO CEO and Investor Conference

Dyadic International, Inc. (AMEX:DIL), a biotechnology
company engaged in the development, manufacture and sale of biological
products, announced today that its President and CEO, Mark Emalfarb,
will present at the BIO CEO and Investor Conference, to be held on
February 13-15, 2006 at The Waldorf Astoria Hotel in New York City.
The presentation will take place in the Empire Room at 11:30 AM EST on
Tuesday, February 14, 2006. Presentation slides will be available on
the Dyadic website at http://www.dyadic-group.com.
   The 2006 Biotechnology Industry Organization CEO & Investor
Conference will highlight commercial advances in bioethanol. Dyadic
has devoted significant R&D resources over the last decade towards
developing its C1 Host Technology and other proprietary technologies
to produce cellulases and other important enzymes that convert
cellulosic substrates such as corn stover and sugar cane bagasse into
glucose from which bioethanol can be produced, and which are therefore
expected by Dyadic to have direct applicability to the bioethanol
segment of the industry.

Industry Organization press release entitled "BIO CEO and Investor
Conference to Highlight Commercial Advances in Bioethanol," available

industry and to fuel continued industry growth and investments in
2006. Complimentary registration is open to qualified investors and
members of the media at http://www.ceo.bio.org.
