title: Variation of xylanosomal subunit composition of Streptomyces olivaceoviridis by nitrogen sources.
abstract: Besides affecting the xylanases production, different nitrogen sources present in the media also caused changes in the xylanosomal subunit composition of Streptomyces olivaceoviridis E-86. Four xylanosome fractions, purified from the culture supernatant of S. olivaceoviridis E-86 grown on different nitrogen sources, exhibited high specificity towards different xylans and were composed of different subunits. Thus, S. olivaceoviridis E-86 regulates the expression of xylanase activity and varies the xylanosome composition according to the nitrogen sources possibly through the action of the secreted proteases.
