beta-Xylanase produced by Aureobasidium pullulans CBS 58475
1989
Dobberstein, J. | Emeis, C.C.
Aureobasidium pullulans CBS 58475 produced beta-xylanase with an activity of 5 units/ml culture filtrate. Xylose, xylan and complex substrates containing xylose served as strong inducers. Purification of the enzyme was achieved by two sets of gel permeation chromatography. The enzyme has an pH optimum at 4.25 and a temperature optimum at 60 degrees C. At slightly acid pH and temperatures up to 60 degrees C beta-xylanase showed good stability. The analysis of cleavage products classified the beta-xylanase as an endoenzyme. Together with an endopolygalacturonase, the beta-xylanase enhanced the maceration of carrots compared to endopolygalacturonase alone.
