[ 1 ] - Xylanase Production under Solid State Fermentation by Aspergillus niger

 Central composite orthogonal design was applied to quantify relations  of xylanase production, loss of dry matter and change of pH with four critical variables during solid state fermentation of a mixture of wheat bran and wheat straw on which Aspergillus niger CCUG 33991 was cultivated. The studied variables included the percentage of wheat straw, temperature, moisture content, and fermentati...
