Streptomyces flavogriseus HS1: Isolation and Characterization of Extracellular Proteases and Their Compatibility with Laundry Detergents

Figure 6

Stability of crude protease from Streptomyces flavogriseus HS1 in the presence of various commercial solid detergents. The enzyme at 100 U/mL was incubated 1 h at 30°C, 40°C, and 50°C in the presence of solid detergents. The remaining activities were determined at pH 7.0 and 50°C using casein as a substrate. Enzyme activity of control sample without any detergent, incubated under the similar conditions, was taken as 100%.
