Stability and effect of NaCl
Protease activity was reported at presence and absence of NaCl, without NaCl the activity was highest and decreases with increase in
NaCl concentration from 0 to 5% (Fig. 7). In this study only activity of this is considered in response to NaCl not the production it will
be also worthwhile to check production at varying salt concentrations. Protease activity is found stable at 5% NaCl and 50% retained
upto 4hrs (Fig. 8).
