| Abstract | ||
| The ability of the fungi Trichoderma pseudokomngii, Trichoderma harizianum and Gliocladium roseum to produce Polygalacturonase (PG), Polygalacturonase transeliminase (PGT), Carboxy methyl cellulase (CMCase) and protease were studied in culture medium filtrates as well as mycelial mats. The study revealed that (PG) in the culture medium filtrate of each fungus had higher activity than in that in the mycelial mat. While there is no significant difference in it's activity between the culture medium filtrate and mycelial mat in the three fungi (PGT) activity of T. harizianum culture medium filtrate had significant difference from that of the other fungi wheares (PGT) had significant difference between G. roseum culture medium filtrate and it's mycelial mat. While T. pseudokomngii had the reverse. The results revealed that there is no significant difference in the (CMCase) activity of the culture medium filtrate for T. pseudokomngii and T. harizianum. Also no significant difference has been found in the enzyme activity of the mycelial mat for the three fungi. The enzymeprotease had higher activity in the G. roseum culture medium than of T. pseudokomngii and T. harizianum . | ||
