Abstract: <smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="country-region"><smarttagtype namespaceuri="urn:schemas-microsoft-com:office:smarttags" name="place"> Fish scale, the chief waste material of fish processing industries, was enzymatically hydrolyzed by protease of <i style="">Aspergillus niger</i> AB<sub>100</sub> to produce soluble protein for use as organic fertilizer. Optimum inorganic nutrients were found to be: MgSO<sub>4</sub>, 0.75; K<sub>2</sub>HPO<sub>4</sub>, 0.2; and KCl, 0.075%. <i style="">A. niger</i> AB<sub>100 </sub>required FeSO<sub>4</sub>.7H<sub>2</sub>O (5 μg/ml) and ZnSO<sub>4</sub>.7H<sub>2</sub>O (15 μg/ml) for higher amount of protease production and yield. The optimum values for the tested cost-effective nutrients for the maximum protease production were: Defatted soybean-meal, 0.2; Peptone, 0.3; and Corn-steep-liquor, 0.2%. Biomass growth was not related proportionately in every case with that of enzyme production and protein solubilisation but protease production shows a positive correlation with hydrolysis of scale to produce soluble protein. </smarttagtype></smarttagtype>
