Recombinant cells, dna constructs, vectors and procedures for the expression of degrading enzymes of phytats in desired proportions.

A RECOMBINANT COMBINATION CEPA AND THAT IS ABLE TO OVEREXPRESS AT LEAST TWO DIFFERENT GENES UNDER GOD SEPARATE PROMOTERS IN FILAMENTARY FUNGES. GENES CODIFY FITASE AND PHOSPHATE ACID TO PH 2.5. PREFERREDLY THE PROMOTERS DESIRED OF THE TWO ENZYMES BY RECOMBINATING DNA TECHNIQUES ARE PREFERRED. THE ENZYMES MIX SHOWS A COOPERANT EFFECT ON THE DEGRADATION OF THE FITIC ACID AND ITS SALTS. THE PREFERRED PROPORTIONS OF THE TWO ENZYMES ARE APPROXIMATELY 3: 1 TO APPROXIMATELY 16: 1. DNA SEQUENCES IS ISOLATED FROM AN ASPERGILLUS NIGER ALQU0234 (ATCCDISNTITO 38854) OF FREE TYPE.
