title: A novel, ultra-large xylanolytic complex (xylanosome) secreted by Streptomyces olivaceoviridis.
abstract: The production of a novel, very large xylanolytic complex (xylanosome) by Streptomyces olivaceoviridis E-86 is reported. The molecular weight was approx. 1200 kDa as determined by native gradient gel electrophoresis. Corncob xylan was the best inducer of xylanosome formation. The xylanosome was produced when the organism was grown for 5 d between pH 4.5-6 and at 27.5 to 35 degrees C.
