Abstract: 

It was shown that all isolated fungi had capacity to produce xylanase. Xylanase from Trichoderma harzianum, The maximum xylanase activity was found at 30 ^°C temperature,7 pH, 5% w/v  concentration pods, 192 hour incubation time. Xylanase from T.viride , The maximum xylanase activity was found at 25 ^°C temperature,6.5 pH, 4% w/v  concentration pods, 120 hour incubation time. Xylanase from T.longibrachiatum, The maximum xylanase activity was found at 35 ^°C temperature,7 pH, 4% w/v  concentration pods, 168 hour incubation time. Xylanase from T.asperellum, The maximum xylanase activity was found at 40 ^°C temperature,6 pH, 4% w/v  concentration pods, 168 hour incubation time. 

Keywords: xylanase, Trichoderma spp, temperature, pH, concentration pods, incubation time.
