Extracellular Protease Activities in Relation to Xylanase Secretion in an Alkalophilic Bacillus Sp
The proteolytic activity of an alkalophilic Bacillus sp. (NCL 87-6-10) correlates with xylanase secretion. Addition of DL-norvaline, glycine or Casamino acids to a medium formulated for xylanase production resulted in 2-5-fold enhancement of xylanase secretion (8 to 45 lU/ml), Inhibition of proteolytic activity is a possible mechanism for enhanced xylanase activity.
