Table 3 Activities of the enzymes used in hydrolysis

From: Enzymatic hydrolysis of steam-pretreated lignocellulosic materials with Trichoderma atroviride enzymes produced in-house

Enzyme Enzyme activity
  FPA (FPU/g) β-glucosidase (IU/g) Xylanase (IU/g) β-xylosidase (IU/g) Endoglucanase (IU/g) Mannanase (IU/g) β-mannosidase (IU/g)
Celluclast 1.5 L 56.2 30.8 750 63.6 13087 122 ~0.08
Novozym 188 n.d. 502 34.7 6.7 296 17.9 5.4
Multifect xylanase 0.15 26.6 22969 26.5 454 n.a. n.a.
Pulpzyme HC 17.9 12.9 1343 118.2 6961 n.a. n.a.
F-1663/S 0.36 7.6 5.0 <0.01 71.6 1.1 ~0.02
F-1663/WS 0.36 5.2 39.5 ~0.05 72.7 0.98 ~0.02

  1. FPA: filter paper activity; n.d.: not detectable.; n.a.: not analyzed.
  2. F-1663/S, WS, B: the crude enzyme supernatants of Trichoderma atroviride TUB F-1663 produced on steam-pretreated spruce, wheat straw and sugarcane bagasse.
  3. The activities presented are the mean values of at least two separate measurements. The standard deviations are <10%, and mainly 1–4% for FPA, <10% for β-glucosidase, 1–5% for xylanase and β-xylosidase, mostly around 10% for endoglucanase, and 5–10% for mannanase and β-mannosidase measurement.
