In fungal cultures, it is used as a carbon source and inducer of polygalacturonases.Polygalacturonic acid has been used in a study to assess an alkaline-active and alkali-stable pectate lyase from Streptomyces sp. S27 with potential in the textile industry. It has also been used in a study that investigated optimization of production and reaction conditions of polygalacturonase from Byssochlamys fulva._x000D_ Packaging_x000D_ 5, 25, 100, 500 g in poly bottle_x000D_ Biochem/physiol Actions_x000D_ In land plants, polygalacturonic acids are major components of cell wall polysaccharides (pectins). Bound polygalacturonase-inhibiting peptides (PGIP) protect pectin from degradation by fungal polygalacturonases.
