Enzymatic Deinking of Waste Papers by Daldenia concentrica, Lepiota sp. And Trametes serialis

The Enzymatic Deinking of Waste Papers by Engineered Bifunctional Chimeric Neutral Lipase – Endoglucanase

Endoglucanase and lipase showed good deinking efficiency for waste papers. The performances could be greatly improved further by the combined use of the two enzymes. To reduce the enzyme production cost and enhance synergistic action of endoglucanase and lipase on laser-printed paper and newspaper, a chimeric enzyme with endoglucanase and lipase activity was constructed and expressed in Pichia ...

effect of medium ph variations on enzymatic deinking efficiency of office waste papers with cellulase from aspergillus niger

enzymatic deinking of xerox printed papers by commercial cellulase from aspergillus niger fungi was investigated. enzymatic treatment was done under constant condition of 0.1 percent enzyme based on oven-dried weight of pulp (102 unit per 100 gram oven-dried pulp), 15 min. treatment time, in four ph levels as 4, 5.7, 8 and 9. then, the effect of ph variation on the appearance and strength prope...

enzymatic deinking of office waste papers in the comparison with conventional chemical method: part 1- appearance and optical properties of pulp

mixed office waste papers are considered as a large source of high quality papers that were printed with non impact printing methods. this papers have involved and economical problem in deinking with conventional chemical methods. in this research enzymatic deinking was done as an alternative for conventional chemical method. enzymatic deinking of xerox machine printed papers with cellulase fro...
