In the early part of the 20 th century, Serratia marcescens was considered a nonpathogenic organism and was used in medical experiments and as a biological warfare To get the most pectinase production from isolate R5-Serratia marcescens, we selected five incubation times (hours) that were used. Distilled water was used as a blank, and the clarity was expressed in percentages [28]. Masi C. Immobilization of Pseudomonas Aeruginosa in different matrices for the production of alkaline protease.

As a result, pectinase activity increased as temperature increased and slightly decreased after crossing the optimal temperature of 35C. The purified pectinase was applied in the fruit juice-making process to test the clarity of the juice. Serratia infection is responsible for about 2% of nosocomial infections of the bloodstream, lower respiratory tract, urinary tract, surgical wounds, and skin and soft tissues in adult patients. sodium salt as the sole source of carbon.
