The possibility of xylose production on an industrial scale from hard wood xylan has been studied by using Trichoderma viride xylanases. The following observations were made through this investigation. 1) The saccharifying activity of Trichoderma viride xylanases was inhibited by sodium chloride, and this activity decreased as the concentration of salt was increased up to 10%. 2) Xylose also acted as an inhibitor of the saccharifying activity. In this case the saccharifying activity of Trichoderma viride xylanases decreased with an increase of the concentration of xylose up to 15%, at which the activity was reduced to zero. 3) In order to promote xylan hydrolysis with xylanases of Trichoderma viride, a two-stage reaction process, in which a new xylanase solution was added to the supernatant of the first hydrolyzate was adopted. This process could reduce the reaction time to about one half of the ordinary single stage process, giving a similar result from the macroscopic point of view.
