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 ...
متن کاملNovel Sources of Fungal Cellulases for Efficient Deinking of Composite Paper Waste
Twenty thermophilic/thermotolerant fungal strains were isolated from compositing soils and screened for production of different enzymes (Endoglucanases, β-glucosidase, Fpase and xylanases) to assess their deinking efficiency. Three isolates, Aspergillus sp. AMA, Aspergillus terreus AN1, and Myceliophthora fergusii T4I, identified on the basis of morphological and sequencing of amplified ITS1-5....
متن کاملEnzymatic versus chemical deinking of non-impact ink printed paper.
Enzymatic versus chemical deinking is examined for MOW and photocopy prints. Several enzymatic preparations and two fibre/ink particle separation methods are tested. Deinking was monitored by image analysis and standard pulp and paper characterisation procedures. The effectiveness of the fibre/ink particle separation method depends on the ink particle's size: for smaller particles a washing ste...
متن کاملEnzymatic Production of Glucose from Waste Paper
Municipal wastes have become a severe problem in developed and developing countries during the last century, paper being the main constituent. Not all of the waste paper can be recycled, and therefore alternative procedures for the use of the remaining material should be pursued. The aim of the present work was the application of cellulases for waste paper treatment and the subsequent glucose p...
متن کاملMicrobial Deinking of Printed Paper
In this study we report the deinking of printed paper using microorganisms isolated from oil contaminated soil. The microorganisms producing lipase and esterase enzymes were screened using tributyrin agar. Deinking of the pulp was carried out using screened microorganisms and the preliminary identification of the microorganism that showed effective deinking was carried out by biochemical tests ...
