Amino acids such as DL-2-amino-n-butyric acid, DL-alanine, L-lysine monohyd
rochloride, DL-valine and L-proline enhanced total xylanase production from
Staphylococcus sp. SG-13 up to 5.5-fold. The present study showed that xyl
anase production has mainly been governed by the chemical structure of amin
o acids and their analogues.
