Influence of growth conditions on the production of xylanolytic enzymes by Trametes trogii
Various nitrogen and carbon sources were examined as inducers of the production of endoxylanase and β-xylosidase by Trametes trogii. T. trogii grown on xylan plus crystalline cellulose provided supernatants with the highest enzymatic activities. Organic nitrogen sources (especially asparagine and ca...
