Abstract: | Xylan extraction from corncob is done by using alkaline as solvent. Xylan extraction from comcob could give the yields as 10.9%. One percent of corncob xylan is useti as substrate to produce the xylanase, compared to oatspelt xylan. Immobilization of xylanase was performed using 1% EudragifTll S100 solution (wlv), with 5:1 volume ratio of xylanase and 1 % EudragifTM S100 (wlv). Activity of the immobilized xylanase was decteased to 23.97% compared with free xylanase. Immobilized xylanase have optimum pH and temperature at 6.0 and 40't: respectively, have also thermal stability at 30-40't: for an hour. immobilization xylanase could be reused, but its activity decreased to 52.38% after 3 times application. Key words : xilanase, Streptomyces, amobile |
