Production and characterization of extracellular polygalacturonase by Erwinia carotovora MTCC 1428. Pectinases break down pectin, causing a decrease in viscosity and the formation of clusters, making centrifugation or filtration easier. References. About 2ml of the three hours bacterial cultures (log phase bacteria) were inoculated to a pre-sterilized fermentation medium to maintain pH 8 [43] and incubated at 30C using a rotary shaker at 125rpm for 48h. At the closed fermentation time, the production medium was centrifuged at 10,000rpm for 10min.

The reducing sugar content of each fruit juice sample increased after treatment by pectinase (Table 10), which is probably related to the liberation of reducing sugar after the degradation of pectin compounds. Some bacterial species, such asEntero bactertabaci NR14667,could produce the highest pectinase activity at 0.3% of pectin concentration, as reported by Obafemi et al., [30]. Springer Nature.

The yield variation of apple juice between control and crude pectinase was 20%. The effect of different pH of fermentation medium on pectinase production by bacterial isolate R5-Serratia marcescens was studied. The production of pectinase was optimized by using four parameters namely, fermentation time, temperature, pH, and substrate concentration. Pectinase activity was determined by measuring the amount of released reducing sugar under assay conditions or by enzymatic degradation of pectin as described Nelson-Somogyi methods. The chemical structure of prodigiosin has been unveiled. Explains the study on optimization of prodigiosin production by serratia marcescens msk1 isolated from air.
