Purification characterization of a catalase from a halotolerant bacterium (Micrococcus sp.)
Some of the enzymes of the wild type Micrococcus sp. strain Gl were detected & it was found that strain Gl was positive for catalase <§c nitratase, then depending on a comparison of intracellular activities for each of catalase & protease enzyme in different NaCl concentrations (2, 10 & 20 %), catalase was choosed for the present study according to its importance & its highest production in all NaCl concentrations. However maximal function of catalase obtained from cells grown in 10 % NaCl as compared with catalase produced from 2 % & 20% NaCl grown cells.
