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

Figure 5

Effect of temperature on activity (a) and stability (b) of the crude protease from Streptomyces flavogriseus HS1. The temperature profile was determined by assaying protease activity at temperatures between 30 and 80°C. The activity of the crude enzyme at 50°C was taken as 100%. The temperature stability was determined by incubating Streptomyces flavogriseus HS1 crude enzyme at temperatures from 40 to 60°C for 1 h. The residual proteolytic activity was determined at regular intervals under standard assay conditions. The original activity before preincubation was taken as 100%.
