Induction of xylanolytic activity in Aureobasiidium pullulans using xerographic paper

摘要

The possibility of using cheaper culture media for endo-1, 4- #beta# -xylanase production by the color variant-derviative strain of Aureobasidium pullulans Y-2311-1, one of the known best producers of this activity, was investigated. Of all the studied alternative substrates, xerographic paper showed to be the best inducer of xylanolytic activity in this strain, usig different carbon sources. The highest extracellular xylancese activity obtained was 15 U/mL when using lactose as the carbon source in the presence of xerographic paper.
