Stabilized Cellulase in Chitosan-Polyvinyl Alcohol Biopolymer Beads for Sustainable Enzymatic Deinking of Recycled Paper. [PDF]
ChemistryOpenA stable and reusable biocatalyst, cellulase@Cs/PVA/Ga, is engineered by immobilizing cellulase onto glutaraldehyde‐activated chitosan (Cs) and coating it with polyvinyl alcohol. This composite system enhances enzymatic stability and efficiency for the sustainable deinking of recycled newspaper, offering a green alternative to harsh chemical treatments.

Separation of Carbon from Deinking Waste by Means of Flotation [PDF]
, 1955 The technique of froth flotation, as practiced in the separation of mineral ores, has been applied to the separation of carbon black from the deinking waste of the paper industry. On the theory that carbon black (from ink) has a positive charge in water,

Pectinase from Microorganisms and Its Industrial Applications. [PDF]
ScientificWorldJournal, 2022 The utilization of microbial pectinase in different industries has been increased in its world demand. The major sources of pectinase are microorganisms mainly bacteria, fungi and yeast. The utilization of low‐cost agro‐industrial wastes as substrates has been preferable in pectinase production.
