                                POWER OF ATTORNEY

     Know all by these  presents,  that the undersigned  hereby  constitutes and
appoints the law firm of Jenkens & Gilchrist,  P.C.,  and each of them,  signing
singly, the undersigned's true and lawful attorney-in-fact to:

          (1) do and  perform  any  and  all  acts  for  and  on  behalf  of the
     undersigned  that may be  necessary  or  desirable to complete and file any
     Form  3,  4,  or 5 with  respect  to the  undersigned's  holdings  of,  and
     transactions  in,  securities  issued  by  Dyadic  International,  Inc.,  a
     Delaware  corporation (the  "Company"),  complete and file any amendment or
     amendments  thereto,  and  timely  file such form  with the  United  States
     Securities  and  Exchange  Commission  and any stock  exchange  or  similar
     authority,  including,  the authority to apply for Edgar access codes or to
     change such codes, as necessary; and

          (2) take any other action of any type  whatsoever in  connection  with
     the foregoing  which,  in the opinion of such  attorney-in-fact,  may be of
     benefit  to,  in  the  best  interest  of,  or  legally  required  by,  the
     undersigned,  it being  understood  that  the  documents  executed  by such
     attorney-in-fact  on behalf of the  undersigned  pursuant  to this Power of
     Attorney  shall be in such form and shall contain such terms and conditions
     as such attorney-in-fact may approve in such attorney-in-fact's discretion.

     The undersigned hereby grants to each such  attorney-in-fact full power and
authority  to do and perform any and every act and thing  whatsoever  requisite,
necessary  or proper to be done in the  exercise of any of the rights and powers
herein granted, as fully to all intents and purposes as the undersigned might or
could do if personally  present,  with full power of substitution or revocation,
hereby  ratifying  and  confirming  all  that  such  attorney-in-fact,  or  such
attorney-in-fact's  substitute or substitutes,  shall lawfully do or cause to be
done by virtue of this  Power of  Attorney  and the  rights  and  powers  herein
granted. The undersigned acknowledges that the foregoing  attorneys-in-fact,  in
serving in such  capacity at the request of the  undersigned,  are not assuming,
nor is the Company assuming, any of the undersigned's responsibilities to comply
with Section 16 of the Exchange Act.

     This Power of  Attorney  shall  remain in full  force and effect  until the
undersigned is no longer  required to file Forms 3, 4, and 5 with respect to the
undersigned's  holdings  of,  and  transactions  in,  securities  issued  by the
Company, unless earlier revoked by the undersigned in a signed writing delivered
to the foregoing attorneys-in-fact.

     IN WITNESS WHEREOF, the undersigned has caused this Power of Attorney to be
executed as of this 23rd day of May, 2005.
