When the pH is below 6.8, phenol red is yellow. The efficiency of Pectinolytic enzymes in fruit juice clarity is, however, reliant on the amount of pectin and pectinases available in the substrate, resulting in better juice extraction and clarification [14, 24]. The test shows the bacterial decarboxylation 1999;42(4):21524. The The production media was sterilized at 121C for 15min and inoculation with 2ml of overnight bacterial cultured bacteria. From the application of pectinase, the volume of juice treated with both crude and purified pectinase varied with the type of fruit used in the process.

Serial dilution and spread plate methods were the techniques used to isolate the target to pectinase enzyme-producing bacteria using Nutrient agar media [55]. 2010. As a result, observed in Table 7, pectinase activity increased with increased substrate concentration (pectin) up to the optimal concentration and decreased after the optimal substrate concentration. Dr. Coombs, Serratia marcescens is a common nosocomial pathogen that was the unknown bacteria in Bertrand X, Dowzicky MJ. This study finding shows that this bacterial isolate, R5-Serratia marcescens,requires an alkaline condition in pectinase production processes [24, 39].
