Figure 3.

Hemicellulolytic enzyme production by T. xylanilyticus on various substrates during the stationary phase. (a) endoxylanase activity; (b) xylosidase activity; (c) feruloyl-esterase activity; (d) acetyl esterase activity; and (e) arabinofuranosidase activity. Values are the means of samples performed in triplicate with standard deviation. Activities are expressed as IU/mg of protein or as mIU/mg of protein and represent the sum of extracellular, cytoplasmic and membrane-associated activities. G, glucose; X, xylan; WB, wheat bran; and WS, wheat straw.
