Yes, there is specific enzymes from Aspergillus niger  which can help to migrate; usually a specific trait of cellulase and hemicellulase has diverse effective based on the furnish type. Laser jet has higher efficiency compare to others.

Thanks for your interesting Dear Mohani Sain. I searched some papers and decided to use cellulase. 

The enzymes that are useful for deinking include lipases, esterases, pectinases,hemicellulases,cellulases, and ligninolytic enzymes.

Dear Shaardesh, I will use only one enzyme which is cellulase. I want to know your opinion about this. Has the cellulase the best result in deinking?

Hi.

For cellulase enzymes:

The best pH condition is neutral about 7. But the best brightness was achieved by Amylase enzyme ( Hader H. Alzate Gil., Andres Mauricio Dovale S., VirneyHadely Chala L., Oscar A. Muñoz., Ana Elisa Casas B., German Camilo Quintana M., Jorge A. Velasquez J. O PAPEL vol. 74, num. 8, pp. 61 - 65 AUG 2013.

For surface roughness:

1) Cellulase enzyme. 2) cellulase + xylanase enzymes. 3) cellulase + xylanase + amylase enzymes are the best. (DHARM DUTT, C. H. TYAGI, R. P. SINGH

and A. KUMAR. Cellulose Chem. Technol., 46 (9-10), 611-623. 2012)

It depends on the response on impact  or nonimpcat ink like laser ink.My suggestion is the ink is attache through xyaln to cellulase Plz use combination of cellulose and xyalanase. If cellulase is used only, there may be chances of yield loss. and DP loss, Someone  above have suggested you  lipase and othe enzymes in combination. I do agree

Thanks for your interesting, Dear Sanjay

Try some of the polyphenol oxidase like laccase which will add a molecule of water at the appropriate place which carrying out the oxidation.

Thank you Dear Jai. 

In the attached paper researchers found that the deinking efficiency of pulps made from treated pulps with commercial cellulase and floated with ethoxylated fatty alcohol of HLB (Hydrophile-Lipophile Balance) 12 at 50 °C was increased significantly compared with other pulps. 

Dear Mohammad,  firstly Thanks for your interest. I am pulping mow and onp according to ingede method 11. I use NaOH, Na2SiO3, H2O2 and oleik acid as chemicals. I will not use other chems or fatty acids. I was not sure which enzyme i would use but I decided to use only cellulase. Now I need to determine amount of the cellulase which is used in My study.  

Dear Mustafa, as I read in some papers you can use 0.1% cellulase (based on oven dried weight of pulp).

Dear Mohammad, it is written also another amount like U/g. in some papers. Which One is better for use, percentage or U/g? 

Dear Mustafa, yes You said correctly. Both of them are correct. However, I think  U/g is better. If you can find amount of U/g pulp.

The enzyme unit (U) is a unit for the amount of a particular enzyme.
