General description

Calcium oxalate (CaC2O4) belongs to the class of oxalates that are associated with soils and lead litter. It forms crystals that are free-living, pathogenic, and plant symbiotic fungi. It is formed by the re-precipitation of calcium as the oxalate.[1]

Pectinase is widely used in juice production, food processes, and other fields. However, owing to poor stability, free pectinase is difficult to separate from a substrate after hydrolysis and cannot be reused, and thus its industrial use is limited. Immobilized
