The cells were harvested from bacterial culture isolate by centrifugation and were suspended in Tris-HCl buffer of pH 8.0. The optical density (O. D.) of cells was measured at 600nm and each time cells of 21.5 optical densities (O. D.) were disrupted and used for the purification of the enzyme. Purification of superoxide dismutase from SPB-13. Ammonium sulphate precipitation method was used for concentrating the proteins. After this, the enzyme was further purified by DEAE-Sepharose column. The DEAE-sepharose column was loaded with 3ml of concentrated protein. The enzyme activity was only recorded in fractions ranging from 22, 23, 24, 25, 26, 27 and 28. These fractions were polled together. The polled fractions along with crude enzyme were checked for purity by SDS-PAGE. The maximum activity of superoxide dismutase of SPB-13 was found to be in Tris-HCl buffer, 60mM molarity, pH 8.0, incubation time was found to be 2.0 minutes, incubation temperature 450C. An enzyme concentration of 10 g was found to be optimum. Thermostability of superoxide dismutase was checked and enzyme was found to be thermostable upto 550C for 60 minutes.

In this book hybrid systems are studied and explained one by one with number of presented simulation results . Firstly we observe result of hybrid system and observe result of Stability analysis and proposed power management strategies using Homer Hybrid optimization Model of renewable energy resources. Hybrid Systems are found to be primarily exponentially increasing more penetration of renewable energy sources with availability and reduce burden on capital cost. The optimum and simulation values are observed on the basis of monthly data of wind and hydro. in case of MATLAB simulation hydro is more stable than wind, but in homer hydro cost is 22170$ and wind net present cost is 22000$. Instillation cost of wind is more than that of hydro power system later its proves to be very cheap.
