Saxena White P.A. Files Shareholder Suit Against Dyadic International, Inc.

BOCA RATON, FL (AMEX: DIL) in the United States District Court for the Southern District of Florida.

You may obtain a copy of the complaint from the Court, by contacting Saxena White P.A. through its website www.saxenawhite.com, by emailing [e-mail] or [e-mail] or by calling [phone].

The complaint seeks damages for violations of federal securities laws on behalf of all investors who acquired Dyadic securities between November 10, 2006 and April 23, 2007, inclusive (the "Class Period").

The complaint alleges operational and financial improprieties perpetrated by the Company and its Asian subsidiaries approved by the Defendants, which culminated in an internal investigation and subsequent firing of the Company's Chairman and Chief Executive Officer Mark A. Emalfarb. As a result of the improprieties in the Company's Asian subsidiaries and the subsequent internal investigation, the Company has abandoned its Asian operations. The Company's stock was artificially inflated as a result of the material omissions and misstatements contained within the Company's publicly filed financial statements and reports. Its stock is currently suspended for trading on the American Stock Exchange and is at risk of being delisted, resulting in total loss of equity for owners of Dyadic's securities.
